How do I use the manual?

The Device core manual is a table view of available and supported parameters of a device core.

image-1646140040512.png

Blackmagic Design - Videohub Device Core Manual example

On the left side we have listed all available parameters, and in the top row we list all available models.
Then you can find the model that you want to work with and read which parameters are supported for you exact model




Introduction to Blue Pill Device Cores

Parameter List- How To

How to use the parameter list found on devices.skaarhoj.com

In this example our goal is: Determine what parameters can be controlled for the RED Komodo camera 

image-1651836346288.png

In the new window you can see a table with different columns. The first is Parameter, and contains the specific functions that can be controlled in this core. The next columns is for models supported in this devicecore. In our instance its 2 different cameras, the Komodo and V-Raptor.

 

 

These parameter list are related to the version of the devicecore you are running. So when troubleshooting please be aware of what verison of the device core you are running. (Information about the version is located on the top of the page)

Arri Camera settings

The SKAARHOJ Arri device core can control Arri Cameras over CAP and older cameras over SSCP.
Please make sure to adjust the settings in the camera(s).


Arri Amira & Arri Alexa Mini

- Enable CAP in the menu
- Use Arri Multicam Look file, otherwise you might not be able to change color parameters
- Enable Multicam Mode, set SSCP IP to the IP of your SKAARHOJ Panel

Arri Alexa Mini LF

This camera only supports CAP, which makes setup easier
- Enable CAP in the menu, check the set password (default: arri)
- Use Arri Multicam Look file, otherwise you might not be able to change color parameters
- Enable Multicam Mode, set SSCP IP to the IP of your SKAARHOJ Panel

Arri Alexa35

This camera only supports CAP, which makes setup easier
- Enable CAP in the menu, check the set password (default: arri)
- Make sure your camera is fully up to date and has the Arri Multicam License
- Turn on Live Painting in the menu
- Duplicate the default Look File, otherwise you might not be able to change color parameters

Biamp Tesira

The Biamp Tesira core has two different models, the Manual model and the Auto model.

Manual Model

The manual model works well for very simple setups, that only needs control of a few parameters. It requires a little more setup, but will not use as many resources on the Blue Pill.

Auto Model

The auto model works by automatically reading the config running on the Tesira, and configuring the controllable parameters to fit them. This is the easiest model in most cases, and is also the one working with AudioClass configs.

Setup

Manual Model

This is a guide on how to connect and control a Biamp Tesira audio processor. Since the Biamp Tesira uses 'Block names' and 'Channel numbers inside a block' there is an extra setup-layer involved, compared to other devices.

Please note: This guide covers the 'Manual Tesira' model.

Add device

On Reactor > Home page you click 'Add Device' to open the devices list. Tesira can by auto discovered. If you don't see the Tesira, you may have to go to the 'Packages' page and manually install the 'core-biamp-tesira' package.

When adding the Tesira, please select the Model Id : Manual Tesira.

image.png

Create custom configuration

We have not yet made any default configurations for the Biamp Tesira. This means you must make your own configuration to assign commands to buttons/faders/etc.

Next to your device icon, open the Configuration pop-up menu and select 'Create custom configuration'. Give it a name and click 'Create'.

custom-config.png

Control using 'Dimensions'

Biamp Tesira is a very flexible audio processor. Instead of just having fixed 'channel numbers' you have both 'Block names' and 'Channel number within a block'. Because of this we need an extra layer to point towards the desired control. We call these 'Dimensions'.

A 'Dimension' is a number, which is linked to a 'Block name' and a 'Channel number'.

For example, we can specify:

Then we can send the command:

The actual commands are:

You can send all 3 commands in a row from a button using a 'Multi behavior'.

multi-behavior.png

NOTE: You only need to specify Dimensions once until you reboot the controller. (You can avoid having 3 commands on every button by using Virtual Triggers to setup the dimension at startup - see below.)

NOTE: Depending on the block, the Dimension will include different parameters. Fx. a 'Level Block' includes; Level, Mute, and Label. Other blocks include other parameters.

Dimension count

By default there are 25 Dimensions available for each block type. This can be changed in: Home page > click Biamp Tesira device core name to open its settings > Edit 'Manual dimension count'

image.png

Use Virtual Triggers for Dimension setup

Instead of sending 3 commands from each button, you can pre-configure all 'Dimensions' using Virtual Triggers. This way you specify the link between 'Block name', 'Channel number' and 'Dimension number' once at startup. After this, when sending commands you just use one command that includes the 'Dimension number'.

Example of Virtual Trigger that defines 4 dimensions (4 channels in the same block):

IF:    At startup and Tesira is connected
THEN: 

After this you only need to send one command from buttons/faders. For example:

'IF' screenshot:

if.png

'THEN' screenshot (using one Event Handler with 'Binary > Sequence'):

then.png

Auto Model

Add device

On Reactor > Home page you click 'Add Device' to open the devices list. Tesira can by auto discovered. If you don't see the Tesira, you may have to go to the 'Packages' page and manually install the 'core-biamp-tesira' package.

When adding the Tesira, please select the Model Id : Auto Tesira.

image.png

When the device has been added, the device config can be opened by clicking the name.
Here you would find the following settings. Remember to set username and password here.
The first time you connect, the 'Regenerate auto' should be enabled. This reads the config from the Tesira, and generates the parameters needed.

image.png

When the device states 'Connected', the Parameter List can be opened and reviewed. It is grouped into the different block types, and shows what parameters can be controlled on each block type.
Each parameter should show some different dimensions. The first specifying the Instance Id of that dimension, and the second and possibly third specifies the channel, inputs or outputs available for control.

image.png

This is an example of a parameter in the Parameter List. The left side has the label, description and name. The right side shows the control and feedback of of the parameter, and the dimensions described above.

In this case, we see 4 level blocks, with 4 channels each. Each block might not have 4 channels, but that number is set to the block with the highest channel count.

Now you are ready to either add channels to an Audio Class config, or start your own configuration from scratch.

BirdDog Cameras

All Blue Pill integrations for the BirdDog cameras have been made using their NDI 5 firmwares.

SHUTTER VALUES

The shutter values on the BirdDog camera are different depending on which video format you are using. The camera does not make it known to the Skaarhoj panel which value range is needed. To solve this, there is a Video Mode parameter that will allow you to tell the panel if you are using NTSC or PAL value ranges. 

Video Mode is available starting with Core-Protocol-Visca v0.2.7 on the packages page.

Screenshot 2023-06-20 at 09.14.59.png

This value may need to be reset after camera or panel reboot. 

MAPPING

By default, the Video Mode parameter is available in the Visca-BirdDog Pro Class configuration for PTZ Extreme and RCP Pro/RCPv2 on the System Page. 

Video Mode was added to the default configuration with Reactor v1.0.8-pre1 on the packages page.

Screenshot 2023-06-20 at 09.22.05.png

For other configurations or when using Visca-AllStars configuration it is necessary to add the parameter to the menu you desire. 

The quickest way to map the parameter would be to go to the Configuration Page, then put the Controller Section into either Simulation Mode which allows you to control the panel from the screen or in Listening Mode which allows you to press buttons on your physical panel to control which HWC you want to edit. 

Screenshot 2023-06-20 at 09.33.26.png

Screenshot 2023-06-20 at 09.32.55.png

Using either method, navigate to the specific spot you want to map the parameter. In the example below I have selected Encoder 3 in the Various layer.

Screenshot 2023-06-20 at 09.37.50.png

In the Inspector section, click Edit above the Parameter you are either replacing or if blank, where you are adding. 

This will open the editor.

Since this change should effect any BirdDog cameras on the panel, select the Select Core (Advanced) option and not a specific camera. If you are mixing different brands of visca cameras, note that this change would effect those as well. 

Screenshot 2023-06-20 at 09.42.11.png

To make sure the parameter is following the camera select, when using our default configurations, the first set up drop downs should tie the parameter to the Variable: DeviceIndex. These options should be available in the marked drop downs. 

Screenshot 2023-06-20 at 09.45.55.png

Next select the correct parameter in the Parameter Name field. Please note that as the visca core is designed for a large number of cameras, some parameters may have similar names. It is possible to double check which is the correct parameter for your model of camera in the Parameter List 

Screenshot 2023-06-20 at 09.47.54.png

Once the correct parameter has been selected, press Submit. 

It is also necessary to select the correct Behavior (prebuilt definition of how the hardware component should act). In this instance it should be StepChange, meaning it will step through the various options available. 

Screenshot 2023-06-20 at 09.51.38.png

The parameter should then appear on the panel in the place it was set and be ready to test. If it does not, try restarting the Reactor package on the Packages Page. Or double check it was place in the correct spot. 


Blackmagic Camera Control via Atem

It is possible to control your Blackmagic cameras through an Atem switcher using your Skaarhoj Blue Pill panel. 

  1. Make sure you are have installed the BMD Atem device core package v0.0.6-pre21 or later. You can see what version you are currently using on the Packages page. packages.png
  2. Add an instance of your Atem switcher on the Home Page under Devices and input its IP address on your network. 

    Please note: If you are using an Atem Constellation 8K in 4K mode, you need to select the Atem Constellation 4K to make sure all the correct settings are applied. If you are using it in 8K mode, select the Atem Constellation 8K.

    Add Atem.png
  3. Using manual discovery, add your BMD cameras. Make sure you select the model that uses the BMD Atem device core NOT the BMD Cam Control device core.

    Tip: Holding down the shift button on your keyboard while clicking Select will allow you to select multiple cameras.

    Use BMD Atem core.png
  4. In the device details for each camera enter the IP address of the Atem switcher and the camera/input number for each camera. Device Details.png
  5. Select the Generic PTZ Control configuration in the config drop down for your panel.

    Please Note: The Generic PTZ Configuration is available on a large number of controllers. Using this configuration allows for the easy addition and set up of multiple models and brands of cameras. The configuration will be custom to each camera type. 

    Use Generic.png
  6. Add your cameras to the camera selector double checking that the Device Config and Iris Chanel Config drop downs have the BMD ATEM CamControl selected. 

    Please Note: There are some use cases that would use a different Iris Channel Config, but for all lenses that are controlable via the camera this is the correct selection. 

    Check config slots.png
  7. Success! You should be ready to start shading your BMD cameras from your Skaarhoj panel. 

Blackmagic Camera Control via Rest API

Firstly you need to download and install Blackmagic Camera Setup program from here https://www.blackmagicdesign.com/support/family/professional-cameras

in Blackmagic Camera Setup you need to select these checkboxes for able to control the camera throw the REST API

image.png

Note for "REST Camera Control" you only need to have the "Web Media Manager" enabled, the other 2 are more nice to have if you want to use the camera with Davinci Resolve for remote file managing

Canon EOS C500 and EOS C300 (Canon-XC)

The currently recomended Core version for EOS C500 and EOS C300 is depended on the firmware version your cameras is on.
This matrix should explain what Canon-XC core version as appropriate for your camera:

Canon XC Core Version Device Core v0.1.9 or below Device Core v0.2.0-Pre3 or above
Canon EOS C300 Mark III
Canon Firmware v1.0.3.1 or below
 Canon Firmware v1.0.4.1 or above
Canon EOS C500 Mark II
Canon Firmware v1.0.5.1 or below
 Canon Firmware v1.0.6.1 or above

If you do not have the newest firmware and want to update your cameras, then you can find the firmware for both models on the Canon USA website by following these links:

DreamChip Camera Setup and Test

This guide outlines cabling workflows to connect DreamChip cameras to SKAARHOJ-recommended third-party serial converters and test the connection.

IMG_8836.JPG

Cabling Options for DreamChip Cameras with SKAARHOJ Control

image.png

For a workflow involving a DreamChip AtomOne camera mounted on a BR Remote Micro L Pan/Tilt head, we recommend a similar approach:

image.png

If you're curious about the proper cabling for a daisy-chained camera setup, this overview should be helpful:

image.png

Please note that while there is a theoretical standard for this process, there's often some flexibility for slight deviations. However, SKAARHOJ cannot provide specific guidance on these limits; we encourage you to explore and learn from your own experience.

Setup Video

[A video is on the way....]

USB-Serial

The USB-Serial connection requires a SKAARHOJ device with a USB-A port, available on models like the XC8 and Blue Pill Server. Activate the USB-A port via the controller's Settings page. Ensure your device runs skaarOS version 1.2-pre3 or higher.

125+126+104 - DreamChip.001.jpeg

image.png

image.png

For the USB-Serial converter, choose 'USB-Serial' as the connectivity method in the device setup, leaving other fields empty.

image.png

Using a USB hub for multiple connections is feasible, though the assignment order may be random upon startup.

In the core-dreamchip-cam logs, you should see a message like this that confirms connectivity over USB:

image.png

Websocket for SSM500

For the SSM500, select 'Websocket' as the connectivity method. This allows the device core to directly connect with the camera. Enter the camera's IP address and leave all other fields blank.

image.png

Websocket-Serial

With some firmware versions of the WaveShare RS232/485 Ethernet converter, 'Websocket-Serial' is available as a connectivity option, with the default port being 6432. However, there's no clear advantage of using Websocket-Serial over the more common TCP-Serial, although it is supported as an alternative.

image.png

In the WaveShare Serial converter you should find two menu pages that looks like this if it supports websocket connections for RS485:

Screenshot 2023-11-28 at 15.14.01.png

Screenshot 2023-11-28 at 15.13.54.png

Ethernet-Serial Converters

Set up Ethernet-Serial converters using the 'TCP-Serial' connection method in the device configuration, and include the IP address. Only specify the port if it differs from the default 5000, which should be verified in your serial converter's settings. If using multiple cameras on a single converter, ensure their RS485 addresses are unique. This is adjusted with the 'rs485_addr' command, followed by saving the settings.

image.png

In the example, the BusID is set to '2', which is not typical. Usually, you should leave the field empty as most cameras default to an ID of '1'.

Changing Bus ID (RS485 Address) of a DreamChip camera using the Ethernet converter

To change a camera's ID on the bus, use a telnet application like Putty, nc, or telnet. Type '100 identify' to see the responding cameras. To change the ID of camera '1' to '2', enter '1 rs485_addr 2', then confirm with '100 identify'. Save this ID change for future boot-ups by typing '2 save_settings' (2 is the new ID!); the camera will reboot. If you encounter issues, consider using DreamChip's ProVideoGUI application for Windows or consult the camera protocol manual.

Ethernet-Serial Converter Cabling

Using the standard DreamChip cable is preferred if possible. It's a very simple setup:

125+126+104 - DreamChip.002.jpeg

To connect your DreamChip camera to an Ethernet Serial converter of any type, you need a Mini XLR male cable with open wires in the other end. Then you connect it in the following way:

image-1647512462854.png

To achieve a multi camera star connection, you simply insert multiple cables in the converter (for short cable runs). You can also use the power passthrough to have one supply to the converter (12V) feed the camera. Be sure to feed 12V into the converter:

125+126+104 - DreamChip.003.jpeg

Test connection

To connect to the converter using a terminal, employ 'nc' (netcat) or telnet on port 5000. 'nc' sends LF as the line ending, but the SSM500 camera responds to both 'LR' and 'CRLF'. Upon connection, you won’t see a greeting message, but typing '100 identify' and pressing enter will prompt a response from the camera. For example:

kasper@Kaspers-MBP-2 ~ % nc 192.168.10.48 5000

100 identify

id: caterham_hs 1 0 0 ATOM one SSM500

OK

In this instance, we’re connecting to a converter at IP 192.168.10.48. The command sent to the camera is followed by the camera's response. The response indicates the camera's ID (in this case, '1'). With multiple cameras on the same serial bus, each will respond with its ID. Here’s an example with ATOM One, ATOM One Mini, and ATOM One Mini Zoom:

100 identify

id: xbow 1 0 0 ATOM one
OK

id: cooper 2 0 0 ATOM one mini
OK

id: blackline 3 0 0 ATOM one mini Zoom
OK

Note: The converter allows multiple IP connections, but camera responses are broadcast to all clients, irrespective of the command sender. DreamChip cameras are not designed for multiple masters. Only one IP client should actively communicate with the camera, while others may listen. For multi-master setups with DreamChip, use a SKAARHOJ Blue Pill Server with the DreamChip device core for a compatible multi-master interface.

Follow the provided instructions to connect your Ethernet-Serial converter to your network. For WaveShare converters, the default IP is 192.168.0.7. Once connected, configure the Serial setup as shown below for compatibility with DreamChip cameras.

These converters appear to originate from the same factory or brand. While they are not identical and have varying features and behaviors, they most likely represent different iterations of the same platform.

WaveShare RS485 To ETH

IMG_8830.JPG

image.png

Note: Here we left the port (Local Port Number) at "26". We would normally change this to 5000 to make it compatible with our default values in the device core.

USR-TCP232-306

IMG_8832.JPG

image-1647512470167.png

Bug on USR-TCP232-306: It looks like the red TX and green RX LEDs on top of the unit is labeled wrong: On one or more of the units we have tested, it's clear that RX will blink green as we send out content on the serial bus and TX blinks red as we receive content. It feels more intuitive that the TX LED should blink in that case (and vice versa).

The "Link" LED will light up when the device has a network connection. It may not turn of if you pull the plug though - apparently it won't detect such a disconnect.

PUSR USR-W610

https://www.pusr.com/download/WIFI/USR-W610-User-Manual-V1.0.1.01.pdf

The device functioned well when connected via cable, but we encountered difficulties in setting up the Wi-Fi. Despite numerous attempts to connect it as a client to my Access Point, we were unable to get the Wi-Fi to work. This issue is particularly significant since the primary purpose of this device is its Wi-Fi capability. Due to this, we cannot recommend it.

Ember+ DeviceCore

The Ember+ DeviceCore allows bluepills to control Ember+ Systems as Consumers. Using the built in Ember+ Explorer you can browse your devices Ember Tree and configure which parameters are going to be used. Check out this QuickStart Video for setting up your device

Eth-B4 Link Lens Control

Connecting the device inside Blue Pill is simple. 

  1. Add a generic Blackmagic Design camera as a device. This can be the Camea with Original 0db/18dB Range as only Iris is being controlled.  cam.png
  2. In the device details:
    Add the IP address of the Eth-B4 Link as the IP of the camera.
    The Port is 5463.
    Set the Camera ID to match the camera number. 
    The Name is however is easiest for you to identify it.
    The Device ID needs to match the Device ID number of the camera you are connecting it to. If you have your set up includes multiple types of cameras using different device cores (example: a Red and an Arri camera), make sure the Device ID for each camera is unique to help tie it to the B4 Link and lens. 
    Save
    details.png
  3. In the Camera Selector constant set for the Skaarhoj Panel, under Iris Channel Config, select: BMD Cam Control Iris. 
    Iris Chan.png

    Please Note: the Device ID number is used here to tie the camera and the B4 Link/lens together. If two cameras had the same Device ID, they would have conflicting lens control. 

This set up does not use the core-analog-b4 device core package or the B4 Analog via Blue Pill Extension Iris Channel Config. 

Calibration And Setup Of The ETH-B4 Link

Now that we have that out of the way. Let's look at how we can use this new controller. This will work when controlled by either the  Unisketch or Blue Pill platform.

Calibration For Use With Unisketch

If you are using the ETH-B4 Link with a Unisketch controller, please download the manual and follow the Calibration steps in there, for how to ensure that your ETH-B4 Link is calibrated.

In short, connect the lens to the unit, move the selection wheel to the "F" or "15" position and wait for it to show a solid Green on the Tally LED. then your unit is fully calibrated. Power cycle the device and it's ready for use. 

Calibration For Use with Blue Pill

When paired with Blue Pill, please clear the config on the unit, in essence, it's ready to go out of the box. To clear the calibration move the wheel to the "E" or "14" position and wait for the solid "Green" light. Power cycle the device and it's ready for use.

The iris limiting is done by reactor instead, directly from the controller. This is done by holding down "Shift" on the panel and using the "Max" and "Min" buttons that should now appear on the panel. move the joystick/fader on your panel to the furthest position up where the lens reacts and click "Max" then move the lens to the lowest position where the lens reacts or depending on how dark you wanna be able to go, and click "Min". Then your joystick should now limit you to only being able to control within that range, to clear the calibration just hold down the top edge on the button you want to reset.

"Iris Max" = More light, so lower F-values, or joystick/fader up
"Iris Min" = Less Light, so higher F-values, or joystick/fader down

Here can be seen where to find these min/max calibration buttons on some different controllers, while holding shift:

Setup And Tuning Of the PID controller

Relevant for units on firmware v1.0.3 and forward

On firmware v1.0.3 and forward we have added a PID controller to help with the precision, particularly on older lenses. the default tune that the firmware comes with is based on internal testing for the best all-around performance, but might not give an accurate F-stop reading/position on all lenses, but should be better than on older firmware.

If you want to disable this and get back to how it was on v1.0.2 you can do that via the serial monitor in the SKAARHOJ updater. Just type "pid-en=0" and you will be back to how it was.

First of we have a set of new serial commands to work with on the unit for controlling and manipulating the PID controller, and those are:

PID controllers can be tricky to calibrate and tune but allow a lot of control and customisation. We have done some in-house testing over a handful of B4 lenses, of different ages, including one box-lense. And found what we would call a good starting point, it's not the most precise but it's also not the worst. But it should perform pretty identically on a 20-year-old lens vs a 1-year-old lens. It's recommended to have a play at this if you like to tinker or if you think it's missing something for your specific lens. Maybe it's a little slow for your liking or maybe it stutters a bit on your lens. In any case, playing with it and the PID values is not something to be afraid of, as you would not be able to damage your lenses with it as they are limited internally. And if you get way out, you can always run the PID reset command or manually paste in the default or a known working set of values.

For info on how to tune a PID controller, we would recommend reading up on what a PID controller is and what the values fully mean, there are some great resources out there that will do a better job at it than what we could do. Below are some links to some of these places: 

The default PID values that our unit comes with are:

Some of our notes from internal testing of other values that might make good starting points for different uses are:

HTTP Device Core

The HTTP Device Core for Blue Pill, core-protocol-http, allows users to send and to some extend receive and process information via HTTP requests. Effectively, this can help to bridge communication with devices with RESTful APIs where a dedicated device core is not available.

The device core has a basic mode and some more complex features that can come in handy in some cases. It has been designed to align with the feature set of the corresponding HTTP Client device core on the UniSketch platform, but it's far more robust and easy to extend to include new approaches.

Basic Configuration

Each device in the device core has the usual configuration available. Looks like this:

image.png

Cowboy Style

The most straight forward way to use the device core would be to send one-shot triggers cowboystyle. This requires only a minimum of configuration but provides the least amount of long term convenience. This is probably a good place to get started.

image.png

Notice the meta values here - they are essentially the configuration for the individual requests.

Adding a Cowboy Trigger to a panel is basically a matter of combining this parameter with a SKAARHOJ:Trigger master behavior:

image.png

The Meta value fields are the key to the whole thing. They would look like this:

image.png

The meta fields are in fact so called IO references in Reactor and that means you can insert references to device cores, variables, constants etc. For example, some of these values could be derived from a constant like "Behavior:Const:Body". This is important because the value gets parsed and pasting pure JSON into these fields won't work, so to make sure a complex string like JSON gets correctly picked up, it must be prefixed "String:" as you see in the examples.

Now, go have fun, shoot from the hip and see how far you get that way... :-)

Command Configuration

The device core allows you to configure a number of fixed commands too. The advantage is that you can bundle an A and B command into a single action for toggles etc. Also, this is the way you can use meta values with the \p1,\p2, ... placeholders etc. like you can for the TCP and UDP device cores. Finally, it's actually possible to decode some level of status back from the returned content of the device via a regular expression.

Below you see the example from the cowboy style trigger, but with some level of parameterization applied now:

image.png

In reactor this can be applied to a button in this way:

image.png

So to make a similar trigger for off, we can use the same command (2) but change the value of "p2" to 0 instead.

Parsing response and periodic requests

It's possible to parse the response of any request and let a matching part of that response get stored in the device core. This is done by the Matching Return Value field that contains a regular expression. You can study the format of regular expressions elsewhere, but they are basically very powerful and advanced string matching patterns.

Whenever the device core receives feedback from the server it will run the regular expressions set up for the command and if there is a match, it will take the value in parenthesis and store as the status value in the corresponding Status parameter. It's both possible for triggered requests as well as for periodic requests.

Here is an example:

image.png

Now, the return body from this request would look this way:

{
"Agent":{"Model":"3PF","DeviceName":"PowerBOX-E7","MAC":"24:A4:2C:38:DF:E7","SerialNumber":"24A42C38DFE7","JSONVer":"2.2","Time":"1970-01-01T16:51:29+01:00","Uptime":13889,"Version":"2.4.3","OemID":300,"VendorID":0,"NumOutputs":3},
"Outputs":[
{"ID":1,"Name":"PTZ (T8)","State":1,"Action":6,"Delay":2020},
{"ID":2,"Name":"Power output 2","State":0,"Action":6,"Delay":2020},
{"ID":3,"Name":"PoE Switch","State":0,"Action":6,"Delay":2020}
]}

And the regular expression will match exactly the portion of this JSON response that is highlighted in red. All the "\s*" is precautions to make sure any whitespace doesn't throw our parsing off, and there is an assumption that the ID attribute comes before the State attribute, but otherwise it should be a good example of how a regular expression can be built to provide some robustness towards variations. In the above case we have to bypass the Name attribute for example.

The main point is that the value of the State attribute is what we are after, but only when found for ID 1. To capture that value, we enclose it in parenthesis: "....([0-9]+)...."

And this happens every three seconds, so we are essentially monitoring the device for state change - on a single feature! And this also underlines the reason why SKAARHOJ generally integrates device cores custom to each device: There is just not efficient way to get all the state from any device by manually building up a ton of such expressions, capturing only one aspect at a time. And feedback from devices is the holy grails of quality integrations that are not simple pray-and-forget approaches to control.

But... now you have got it for the occasional case where there is only this type of "workaround" to get the job done.

Kessler Crane

Adding and connecting to a Kessler Crane device from the Blue Pill platform

The Blue pill can connect to a Kessler Crane device in two ways, via WiFi or USB. In both cases, there are some special things that needs to be handled for the Blue Pill Core to connect successfully.

First, add your desired device inside the reactor, by clicking the add device and selecting "Add Device Manually". Then search and click add on your desired model.

image-1657270287772.png

You should now be prevented with this device config box:

image-1657270736037.png

If your config box does not have the "Connection Type" option, please click the save button and wait until you see the device on the left side say "Disconnected" or "Connected". If it's your first time installing the core, it will say "Installing Core" wait for that to finish, then restart reactor to load the new Device Config structure.

Clicking this "running" button will give you the option to restart reactor:

image-1657271066379.png
After restarting reactor, click on the device on the left side, and you should now see the "Connection Type" inside the device config popup. Please set this option to your desired setup type and continue the setup below.

Updating your SkaarOS and enabling USB-A

For the Kessler core to connect over USB, you must be on SkaarOS v0.14-pre2 or newer and have the USB-A connector enabled on the settings tab.

Update SkaarOS

To update SkaarOs, go to "Settings" and click "Update".

image-1657272707368.png

This will give you a popup where you select the v0.14 stable version (or higher). If you don't see a stable version for v0.14, enable "Show Pre-Releases" and choose the newest version available, the minimum supported version we need is v0.14-pre2. Then click update and wait for the Blue Pill to finish installing and restart the device.

image-1657272819340.png

Note if you do not see the prerelease option, scroll down to settings and enable "Advanced Mode"

Enable the USB-A connector

To enable the USB-A connector on a Blue Pill device, please go to "Settings" and scroll down to enable it here:

image-1657273253186.png

Connecting over USB

Connecting over USB is very simple but has two caveats that need to be addressed before it will connect.

First, please check with the guide inside the "Updating your SkaarOS and enabling USB" block and make sure you have that set up first.

If you are on a supported SkaarOS version and have the USB-A enabled.

Connect a USB-A to USB-Micro cable between the USB-A connector on the bluepill and the USB-Micro on the Kessler Device.
After that setup the device as shown below, a few things a not in use by the core when connecting over USB and can be left as is, this Includes the IP and Port.

image-1657271798820.png

If you get a green "Connected" status, you are now ready to use the device. If you do not get that, please open the package logs and check if there are any errors. If you get an error like this one, it means that your SkaarOS might not be on a supported version or that the USB is not enabled/connected on both ends.

image-1657274081682.png

Connecting over WiFi

When connecting to a Kessler Crane device over WiFi, you should configure the device like this inside reactor. All the default values should already be correct, as the IP and port of all Kessler sliders are the same when they host their own WiFI.

One thing does need changing from the default, and that is the Connection Type, which needs to be changed from "USB" to "TCP", as it, by default, is set to "USB".

The "Password" field is optional and depends on whether you set a password on the device itself.
The final setup should look like this:

image-1657271830207.png

More info to be added here about how to enable WiFi on the slider themselves and how to connect to the WiFi...

Panasonic Lumix

Tether

The Panasonic Lumix only allows 1 network connected client at a time. This means it is not possible to use both Panasonic's Tether interface and a Skaarhoj panel simultaneously. 

Password

Connectivity to the Panasonic Lumix requires a password. Due to the way the password is usually set in the Lumix, it can be necessary to connect with the Lumix set to the default password: FGHIJ67890

The password needs to be entered in the Device Details section for each connected Lumix camera.

Lumix.png

 

Connectivity Issues

If you encounter connection issues despite all settings appearing correct, we advise performing a factory reset on the camera and using the default password. Crucially, after resetting, avoid connecting the camera with the Lumix Tether application, as it might lock in the camera somehow and thereby prevent the SKAARHOJ device from connecting. The exact cause is unclear, but this solution has been effective for other users.

Panasonic RP150 Controller Setup

 

 

Producer Assistant - Video Follow Audio

The Video Follow Audio model of the Skaarhoj Producer Assistant core, provides functionalities for automated switcher control, based on logic inputs, such as an audio meter.

This can be used in simple scenarios, such as a debate or radio program, to automatically cut to a camera on the person speaking.

This is an advanced topic. To configure the system, knowledge of Skaarhoj Device Core parameters and IO References is expected.

How it works

The Video Follow Audio system, works by monitoring a device core parameter for each person (called participants) in the system. It checks periodically if a new participant is talking more than others, and then cuts to that participant. If the person have been talking for a long time, it will periodically cut to a wide shot (if setup) or the participant previously on as a listening shot.

Requirements

For the system to work, it requires an input parameter for each participant. This will often be an audio meter for the mic the participant is using.

Not all devices provides the same quality of audio meters. Some have a slow update rate, some have a high latency and some are not too precise. This means that though it might work in theory, some parameters are less than ideal for reliable switcher control. If possible, please try it out before you buy the license.

Configuration

To use the Video Follow Audio system, some initial setup has to be done in the device WebUI. In the device configuration menu

Most of the configuration happens in the Device WebUI. To open it, open the device configuration of the home page of Reactor, and press 'Open Device WebUI'. It can also be found in the packages menu.

image.png

The configuration page consists of 3 parts.

When you are finished editing the configuration, remember to press save on the bottom of the page! This will trigger a restart of the system.

Switcher Setup

This page provides the main parameter for controlling the switcher. In this case it is using a Atem switcher and controlling the Program Input Video Source parameter.

It is also possible to provide Safe Sources. These are input numbers with cameras that can also be cut to, for example a wide or audience shot.

image.png

PTZ Cameras

PTZ Cameras can be used to film specific participants, so you don't need a fixed shot on each person. Multiple cameras can be configured. Each camera has an IOReference for how to recall presets and a switcher input number.

In this case we have two Canon Camera using the Canon-XC core. The camera with device index 1 is found on the first input of the switcher and the camera with device index 2 is found on the second.

image.png

Participants

This is where you setup each participant in the system. A participant will need at least a input reference with a logic statement and an action.

Input reference

Each participant have a IO Reference for how the system will read if the participant is talking or not. In most cases this will be an audio meter. They can also have a condition setup. This uses standard logic signs to express how the IO Reference should be checked.

In this example, the IO Reference is a channel meter from a Behringer X32 audio mixer, and the participant will be assumed to be speaking, every time the channel meter is over -18.

Actions

Each participant will need one or more actions to be configured. An action can be either a still camera or a PTZ camera. Both types would need a Switcher Input to specify what source the switcher should cut too. A PTZ camera will also require a preset number, to know what preset to recall, before the camera is selected.

In this example, the participant has both a still camera and a PTZ camera configured, so the system will pick a random of the two.

A PTZ action needs to have a camera configured in the 'PTZ Cameras' section with a matching switcher input for it to work. If a participant only have PTZ cameras configured, the system will try to use a camera that is not currently live. If only the live camera can be used, the system will try to cut to a safe source, before recalling the preset.

Protocol-OSC

Open Sound Control (OSC) is a widely used protocol for controlling all sorts of devices. This is a generic protocol implementation, so you have to know the exact commands your device reacts to, and how to connect to it.

OSC works by sending commands with an address and often also an argument. An example: To control 'level' on a device, the command could look like this:
• Address: '/level/1'
• Argument: '1.5'

Most OSC commands uses slashes in the address to divide the address into fields. The address above '/level/1', could specifies that we want to control the level parameter, on channel number 1.
These addresses needs to be known before hand, and can often be found in the manual or the OSC specifications for the device.

At the moment our OSC device core only works via UDP. This is the standard for most OSC devices, but a few uses TCP.

Configuration

To configure the device you need to set some device specific information.

image.png

Models

The OSC core provides 3 different models to use:

1. Simple model
This model includes parameters for very simple one way OSC control.

A control parameter has to be specified with a few meta parameters.

image.png

Type specific meta parameters.

2. Dynamic model
This model includes everything from the simple model, but also a way to receive feedback on parameters.
Each parameter have a number of dimensions. These dimensions is assigned different commands, that then can be controlled, or could listen to feedback.

For each control type, there are 3 parameters. The control parameter itself, a command parameter and a config parameter. Each of these have the same amount of dimensions.

The other way to setup the control parameters, is through the webui. This offers a easier way to make multiple parameters ready to use. To open the webui, a dynamic or advanced model needs to be configured. Open reactor, and navigate to the 'Packages' menu. Here you can find the osc package, and a button to open the UI.

image.png

At the top of the page, there are a dropdown menu to select what device to configure, along with a row of tabs for each type of parameter available. If a dynamic model has been configured, 4 tabs with the datatypes 'Integers', 'Floats', 'Bools' and 'Strings' are available.

Each tab contains a row of parameter entries to set. Here it is possible to setup everything needed to setup each command to control.

image.png

The dynamic config parameter includes many of the same things as the simple parameter. The new things are:

3. Advanced model
This model includes everything from the both the simple and dynamic model, but also a way to setup multiple dimensions of a parameter. For instance if you have many faders to control, you only have to configure it one time, and it will auto populate the second dimension of control.

The Advance parameters have the same 3 parameters for each type as the dynamic parameters. The main difference is , that when setting the address or feedback, a string formatter can be used. For instance if you have 20 level commands ('/Level/1', '/Level/2', '/Level/n'...). Instead of setting them up one by one, the Address can be set to '/Level/%d', and then the Count meta parameter set to 20. Now the parameter will be populated with 20 sub dimensions to control, one for each level control.
Some parameters will need leading zeros, for instance '/Level/01'. To set this, use '/Level/%02d'. That will make it a width of 2 and pad it with zeros.

Example

As an example, lets say we want to control a simple audio mixer with 12 channels. From the manual, we find the following OSC parameters we want to control:

Fader control - a 0 to 1 float with the address '/mixer/level/x'. The x marks the channel number from 01-12.
Mute control - a 0 or 1 integer with the address '/mixer/mute/x'. 
Pan control - a -100 to 100 integer with the address '/mixer/pan/x'.

In the manual, we also see that in order to get a current value from the device, we can send the address without a value, and it will return the current value.

Since we have multiple channels for each command, we will use an advanced model.

To setup each command, we open the UI as described earlier.

Each of the advanced tabs will be configured as following.

Fader control through floats
image.png

Here the address is setup with the last part as %02d. This is a string formatter that will take the channel number and add is as a number with a width of 2 padded with zeros. Eg. Channel 1 would be: '/mixer/level/01'. 
The feedback is left empty, and will then default to the same as the address.
Ask for feedback is enabled, since we can get the current value by asking for it. 
The min and max is set to the range of the fader, from -90dB to 10dB.
From the manual, we know that the float to send, needs to be from 0-1. To get this, we use a command factor of '(x+90)/100', and the reverse for feedback factor 'x*100-90'.
Finally we set the Count to 12, since that is the amount of channels we want to control. 

Mute control through integers with a bool type
image.png

Most things are setup as above. The only difference is, that the 'Use int' is checked. This tells the core to use an integer of 0 or 1 instead of 'true' or 'false' values. 

Pan control through integers
image.png

Again, many of the things are the same as above. The min and max is now set directly to -100 and 100,  with no factors. This will send the raw value from -100 to 100.

 

PTZ Trace on Blue Pill

PTZ Trace is a feature that simulates the operation of a PTZ (pan-tilt-zoom) camera using pre-recorded speed commands, as if a joystick is controlling it. The commands are usually recorded from an operator who previously maneuvered the camera's pan, tilt, and zoom axes with a joystick.

SKAARHOJ controllers that control VISCA cameras, as well as Panasonic, Canon XC protocol, Vaddio, and Sony's newer PTZ protocol through websockets, incorporate the PTZ Trace functionality as of IBC 2023.

Features

How to use it

PTZ Trace is built into our default configurations and is accessible through the preset recall buttons. To start recording a trace, press and hold the preset button for 3 seconds. After one second, a stationary preset will be recorded, but if you continue to hold down the button for a total of 3 seconds, the button will light up red and the display will indicate "Recording". At this stage, use the joystick to maneuver the camera, and press the same button again to stop the recording.

Once a trace is saved on a preset button, the button turns blue. Pressing the button once arms the trace (amber button color), which recalls the associated preset and positions the camera at the start of the trace. Pressing the button again will commence the playback (green button color) with the display showing a countdown timer.

Note: Features such as looping, ping-pong mode, wait times, and user waits are not yet integrated into the default configurations. We will update this documentation once these features become available.

The trace features are by default in the PTZ configuration but they are not enabled. To enable them navigate to the engineering menu for the configuration. You can see how to access the engineering menu for the various panel configurations here: https://wiki.skaarhoj.com/books/blue-pill-reactor/page/engineering-menu

Please note that these are preliminary tests conducted under non-systematic conditions, primarily to assess the feasibility of the feature. We will provide updated and more comprehensive data in due course.

Technical Notes

PTZ Trace in SKAARHOJ controllers works by replaying pre-recorded pan, tilt, and zoom speed commands to the camera. The accuracy of the playback depends on multiple factors:

Reverse playback (Ping-pong mode) issues

Most cameras tested perform exceptionally well on forward playback, meaning they tend to arrive at the same position consistently during playback. However, in reverse playback (ping-pong mode), substantial differences can be noticed on some cameras. This is due to some cameras interpreting pan and tilt speed commands differently based on the lens' focal length (zoom). Reverse playback essentially involves sending the same speed commands but in reverse order and with inverted polarity. Since a speed command may set the camera in motion differently depending on the current zoom position, reverse playback often ends up in a different place, particularly if zooming was utilized in the process. While it's usually beneficial for a PTZ camera to adjust its pan and tilt speed based on zoom position, it can hamper reverse playback.

On the SKAARHOJ device core side, we strive to play back all speed commands as accurately as possible. The offset from the original timing is typically less than 1ms. However, we must also respect the minimum time required between commands sent to a given camera. Despite this, our tests suggest that the timing precision we achieve is more than sufficient to provide extremely accurate playback.

Raw Panel Device Core

The Blue Pill device core, core-skaarhoj-rawpanel, is used by an application like Reactor to forward parts of a connected panel to external Raw Panel clients while other parts are used by Reactor itself. This aligns with how Raw Panel is natively implemented on UniSketch controllers.

The idea can be understood by the drawing below:


image.png

The actual physical control panel connects to Reactor. The Raw Panel Device core is used to forward triggers from some hardware components to an external client. The rest of the panel is configured in reactor for any kind of use there.

To understand the alternative: panels can generally only be used with a single client, so either an external application or Reactor would have to be connected:

image.png

Configuration

Inside of Reactor there is an example configuration for the Raw Panel device core and a Rack Fusion Live. So, here is the basic project set up with the Raw Panel configuration selected for the Rack Fusion Live:

image.png

The configuration for the Raw Panel device core looks like this:

image.png

Most of this is default values, but one thing is super important: Set the Use Embedded Topology to RACKFUSIONLIVE (in this case). This is how the panel will report itself to connecting clients and it is highly likely that you want this topology to match the actual panel being used.

Now, with an application like Raw Panel Explorer you can scan the network for Raw Panels and connect to them for testing. When the application is started you will see panels on the network:

image.png

Of interest is the fifth line where a Rack Fusion Live with serial ab6a4190-1 is found - that is our forwarded panel! The real panel that Reactor is connected to would be one of the other two panels (serial 435775 or 999923). If you connect to the forwarded panel it will look just like this:

image.png

To the client it will look exactly like any Rack Fusion Live although its served via Reactor. However, the client won't know which hardware components is forwarded and which are not. It has to assume that the full panel is available.

Configuration in Reactor

We should take a closer look at how the chosen configuration actually looks:

image.png

In Reactor it's actually quite simple: For every hardware component on the panel (in the case of the picture above: component 1 = _p1.1) a master behavior from the skaarhoj-rawpanel collection is added to each component. Here it's the "skaarhoj-rawpanel:Button" behavior with the constant "HWCid" set to 1. For encoders there would be a similar action:

image.png

To achieve a mixed control scenario it's just a matter of combining this approach with other device cores, layers etc. in the usual way Reactor works.

Underlying JSON code

Here is a quick glimpse at the JSON code for the layer shown above:

image.png

(This is what you get if you click the tiny button "Edit raw" in a layer)
Lines 30-32 is actually really important - you have to import the "core-skaarhoj-rawpanel" library of master behaviors. Other than that you will find more of less the same setup for each hardware component like you see here for _p1.1. Just copy/paste this around.

Device Core parameters

The device core parameters fall into two categories: Triggers and Feedback.

Triggers

Here are the triggers:

image.png

It's probably not a surprise that there are four triggers: they correspond to the classic four trigger types that Raw Panel operates with:

Feedback

The feedback is also aligned with the Raw Panel protocol and more diverse:

image.png

The Raw State is available and meant to be used to transparently forward the state. This is most likely what you want to use while the others are more easy to mix and match and process further in Reactor if needed.

A deeper study into the configuration found in skaarhoj-rawpanel master behaviors will reveal more details and best practices on all of this.

Mismatched Topologies

In case you choose a different Embedded Topology than the one that matches you panel - or if you try to send HWCid values that doesn't exist on a controller you will generally succeed. Reactor won't keep you from sending a button press for something the client thinks is a T-bar or non-existing. Unless you activate the setting Constrain to Topology setting in the device core configuration:

image.png

Adhoc panels

Alternative to using a known SKAARHOJ topology you can also build an adhoc topology from ground up. If you keep the Use Embedded Topology field unset and enable Training mode, then a topology will be dynamically build up as you send triggers to the panel:

image.png

Assuming we just set this up as Device 2 (make sure to pick another port, such as 9924) it would appear in Raw Panel Explorers network scan like this:

image.png

When you connect you will see this:

image.png

As you start pressing triggers that Reactor forwards to the panel, the Training mode will automatically build up an abstract topology like this:

image.png

In this case, three buttons were pressed (HWCids 1,2,3) , then a fader was moved (it had HWCid 25) and finally an encoder was turned left and right (HWCid 22). As long as the panel is in training mode it will add components to the panel like this. 

Building an abstract panel like this can be useful in cases where the raw panel client rather wants to relate to "3 buttons, a fader and an encoder" type of panel and really doesn't care if in the other end it's mapped onto a Rack Fusion Live, PTZ Extreme or Air Fly Pro. That mapping could be done in any way inside Reactor regardless. When training is done, make sure to disable Training mode.

Building adhoc panels is an advanced option with some quirks related to it for now, so it's advised to discuss application with SKAARHOJ support team first. We really would like to know how you want to use this and help you succeed.




Ross OGP - Model Dump

The Ross OGP core has the ability to capture all device parameter information and save it. This information can be used to help Skaarhoj add new models to the system.

This guide will show how to create a model dump.

1. Connect to device

Connect to the device using a random model. Make sure the device states connected.

image.png

2. Set description prefix

Open the device configuration again and add 'learn_mode' to the start of the description. Press save.

image.png

3. Open logs

Open the device configuration again, and press the 'Core Logs' button.'

image.png

4. Download and send package

After about 30 seconds, you should see something like this in the core logs. If not, please reload the page.

The last log line here shows where to get the file from. For example, if your Skaarhoj panel is on '192.168.3.16', go to '192.168.3.16:8090/learn.zip'. This should begin a download of a zip file. Send this file to support@skaarhoj.com along with as much as possible information regarding the device you are connected too.

Sony FX3

Connection and control of the Sony FX3 is possible via Skaarhoj panels with USB-A ports. This is because the Sony FX3 only supports the Sony Remote SDK using Serial USB and not through wifi or direct network connection. 

Physical Set Up

Using a USB-C to USB-A  cable, connect the Sony FX3 to a Skaarhoj panel with a USB-A port.

Please note, multiple cameras can be control by using a USB hub into the Blue Pill device.

On the Home Page, add the Sony FX3. 

Screenshot 2025-07-01 at 9.43.39 AM.png

Please note, the Sony FX3 needs to be added manually and can not be auto discovered. 
It may also be necessary to enable Show Concepts. 

Screenshot 2025-07-01 at 9.42.14 AM.png

There should be no additional information needed in the device details, simply press save. 

Screenshot 2025-07-01 at 9.46.30 AM.png

You should see confirmation of device connection on the home page. 

Screenshot 2025-07-01 at 9.51.09 AM.png

If you do not see confirmation of connection please try rebooting your Skaarhoj panel and check the USB cable is properly connected. 

Control

Once connection has been established, it is possible to control the Sony FX3 from any Skaarhoj panel connected through the same Blue Pill device. 

If control is to be established from a Skaarhoj panel that is not set up in the same user interface, please see instructions for Sharing Device Cores Across Different Blue Pill Devices.

Sony FX6

You can connect to Sony FX6 camera via cabled Ethernet or Wifi. We strongly suggest to use cabled Ethernet.
This will work with multiple FX6 cameras - they just need to have unique IP addresses.

Wired LAN setup

You need to enable Wired LAN in the camera settings:
• Menu > Network >
   - Access Authentication > Input password > set new password
   - set Wired LAN = ON
   - set Remote Control = ON

Also, you must set a static IP address:
• Menu > Network > Wired LAN > Detail Settings >
   - DHCP = OFF
   - Enter static IP / Subnet / Gateway

network-menu.jpg

USB-C to Ethernet adaptor

To use cabled Ethernet, you need a "USB-C to Ethernet adaptor".
It is critical that you use an adaptor with compatible chip-set:

Note: There are many other adaptors not working. They can even crash the FX6. This includes a chip-set with similar name; AX88179A - (has an A at the end) which does NOT work.

Here is an example of a working adaptor (from a Danish webshop):

NO CONNECTION

If you have the experience that it just wont connect at all, after having been working earlier, please try and restart the camera, there might be a client limit on the device

To be expanded upon.

TCP Device Core / UDP Device Core

The TCP Device Core for Blue Pill, core-protocol-tcp, allows users to send and to some extend receive and process information of TCP to both ASCII and binary servers. Effectively, this can help to bridge communication with devices where a dedicated device core is not available.

The UDP Device Core for Blue Pill, core-protocol-udp, enables the exact same functionality as for TCP, just over a UDP connection.

This page describes how both device cores work, but using core-protocol-tcp as the example. The device cores have both a very basic mode and some more complex features that can come in handy in some cases. It has been designed to align with the corresponding TCP Client device core on the UniSketch platform.

Commands

The commands you can specify and send are ASCII by default and exactly what you see in the string will be sent as ASCII, unless:

Floating point

Inserting a floating point number with \f is based on the parameter p1-p3 being an integer which gets divided by the [scale] number. For example, if you insert \f2/10 then if meta value parameter p2 is a variable with the value 55, it will get formatted as "5.5" in the message.

Example

Say you want to send a command to fire DMEMs on GVG100, in that case you want to send the text string “03 01 DB 00” to fire DMEM 01, send “03 01 DB 01” to fire DMEM 02 etc.
So setting up a command like “03 01 DB \h1” and then using the “p1” meta value through a constant in Reactor would allow you to distribute the same behavior across multiple hardware components on a panel but vary the Dmem value easily.

Testing and tools

An advice is to use the "ipserver" binary tool provided by SKAARHOJ to set up a server to help testing the functionality until you are confident that everything works as expected and would function with the final target device.

Basic Configuration

The device core has some configuration fields:

image.png

Cowboy Style

The most straight forward way to use the device core would be to send one-shot triggers cowboystyle. This requires the minimum of configuration but provides the least amount of long term convenience. This is probably a good place to get started.

image.png

Command Configuration

The device core allows you to configure a number of fixed commands. The advantage is that you can bundle an A and B command into a single action for toggles etc. Also, this is the way you can use meta values with the \p1,\p2, ... placeholders etc. Finally, it's actually possible to decode some level of status back from the returned content of the device via a regular expressing.

The commands configured here will be available through these parameters in the device core:

Examples

Forwarding the position of a fader, 0-1000

Forwarding the position value of a fader requires us to use the "\i" placeholder to insert a dynamic value. The code below demonstrates a behavior called "VolumeFader" that is assumed to control volume on a given channel on a device by sending text strings like "CHx_Vol_n", where x is the channel number and n is the volume. In this case, we assume the device will access the value range of n to go from 0 to 1000 so that it's 1:1 compatible with a Raw Panel fader position value.

Description:


TCP Server Device Core

The TCP Server Device Core for Blue Pill, known as core-skaarhoj-tcpserver, enables users to connect one or multiple TCP clients to the device core, and read/write values to numerous internally stored data types. It's also an implementation of the data register section of the TCP Server device core for UniSketch, mainly for legacy purposes. The key attraction for Blue Pill users is likely the significantly improved capacities:

The device core is generally multi-directional. Most values are set to read/write, and alterations from any client - whether the connected TCP clients or the device core clients - are propagated to other connected clients, ensuring synchronization at all times.

Use cases

The Device Core is an essential tool for ad hoc interactions with Reactor, which is the panel management application found on the majority of SKAARHOJ products. This utility is particularly beneficial for addressing custom integration needs. Below are a few examples:

 

Device Core Setup

In Reactor you would add the device core to the device list. The setup page looks like this:

image.png

Connect as a TCP Client

Using Putty, telnet or nc depending on your platform, you connect to the TCP server by using the IP address of the Blue Pill device hosting the device core and the port number. Here is an example. Connection is silent, there will be no introduction message sent to the connecting client, but typing in "help" and ending with newline (\n or char 10) will show available commands:

image.png

If you are using Putty on Windows, make sure to set it up correctly to send newlines for line endings:

image.png

Try the different commands to get the feel for it.

Example in Reactor

Here is an example of how Reactor can interface with an integer from the device core:

Click a hardware component in Configuration tab and assign a new behavior with an IO reference pointing to the Integer Value parameter of the TCP Server. Select integer #2 for example:

image.png

You will see it in the display of the component, but it has no value:

image.png

Probably the "Change by Step" master behavior was assigned to the button as you selected the parameter, so if you press the button it should assume a value:

image.png

Simultaneously, you should see values reported in the connected TCP Client window:

image.png

In the TCP Client you can try to type in "Int#2=111" and you should see the value reported back in all connected TCP Clients as well as update in Reactor:

image.png

The same can be done with all the other registers.

Tilta Nucleus M

The Tilta Nucleus Core supports control of Tilta Nucleus-M motors via a wired connection.

It operates through a USB-to-UART (TTL) converter. We have tested it using this converter in 3.3V mode:
https://www.waveshare.com/usb-to-ttl-d.htm

Other converters may work, but we cannot guarantee their compatibility. Please ensure you use a 3.3V serial connection only.

A custom cable is required to connect to the 7-pin LEMO connectors on the camera. This cable can be designed to provide both power and control, or control only.

image.png

TSL

If you have a PTZ controller you can use TSL as the Routing trigger. That could be beneficial if you want your Camera selector to also route a source external in equipment using TSL, like Tallyman.

  1. Add Cameras to your Controller

    image.png

  2. Press Camera Selector

    image.png


    1. Fill in Route Index what TSL Address should be used for the specific source
  3. Press Routing Trigger
    1. Add new
    2. Bind to your TSL Device

      image.png

    3. Select TSL Config in the Switcher or Hub section

      image.png

Auto-Discovery Of Livestream Studio

On the Blue Pill platform, we support auto-discovering devices. Livestream Studio 6 does currently not have a native way for us to do this by default, but if you go into settings and add an NDI output, then we can use that for discovery. For that to work, you will need to include at least one of 3 words in one or more outputs:

Once set up, it will look something like the below, and it should now show up in the device discovery list:

vMix v25 +

Connecting To vMix v25

For your Blue Pills to control vMix v25 or v226, please check the setting marked in RED as that needs to be turned on, as shown below.

The settings marked in green are not required but recommended for the security of your vMix setup and to limit others from taking control from outside the LAN network.

Note: vMix v24 is not affected by this and will work out of the box. No changes are needed inside vMix.

Add device inside Reactor

Inside reactor you can add any vMix device like normal, and the only thing you need to add is the IP of your vMix machine. 

We do have the option to change the port number used. Please do not touch it if you don't know what it does. On the Blue pills, we use the TCP port inside vMix, and not the HTTP port that the build-in web controller uses. The vMix TCP port is not user-configurable but locked to port 8099. 

You can still change the port inside reactor for people running very fancy port re-mappings on their network or are running vMix inside a virtual machine, as many do on the AWS platform.

Troubleshooting Connection


Waves Cloud MX

This guide will show you how to connect a Skaarhoj Waveboard to the Waves Cloud MX mixing platform.

On your Cloud MX instance, install the rtpMIDI driver. This will be used to establish a midi connection to the Skaarhoj device.

Once installed, open the rtpMIDI program, and add a new session:

Give the session a name, and press enabled. Make sure that the 'Who may connect to me' setting is set to 'Anyone'.

Open the Cloud MX software, and go to the 'Setup' menu. Add a new Mackie controller. And open its settings window.

Set the input and output port on Device 1 to match the newly created rtpMIDI session. Enable the 'Jog Wheel Adjust Selected Controls' setting, and if wanted, the 'Follow Aux-Sends' flip.

Open reactor on your Skaarhoj device. On the home screen, click the 'Add Device' button on the right side of the screen. 

Go to the 'Add Manually' tap and search for 'Waves'. If nothing shows up, enable the 'Show Concepts' setting. Select the Waves Cloud MX device.

Enter the public IP of your Waves Cloud MX instance, and check that the Remote Port matches the port of the RTP midi session created earlier. In most cases, the default port of 5004 is correct.

Confirm that the device is connected. If not, check that the IP and port is set correctly, and that your Skaarhoj device is connected to the internet.

On your Waveboard, select the 'Waves Cloud MX' configuration.

Now you should be all set to use your Waveboard with Waves Cloud MX.

Adding an additional Waveboard

To use two Waveboards at once, you need to add an extra rtpMIDI session. Notice the new port number on the second session.image.png

Go to the Mackie Control Settings, and add the new rtpMIDI session as Device 2. Make sure Device 1 is still set as the main device.

Add an extra Cloud MX device in Reactor on your first WaveBoard. Set the local and remote port to the new rtpMIDI sessions port.

Make sure that the 2 devices are set with device ID 1 and 2:

On your second WaveBoard, go to the settings menu, and make sure it is set to 'RawPanel Mode'.

On your first Waveboard, select the '2x WaveBoard V2 - Waves Cloud MX' configuration.

Press the 'Select missing panel' and 'Add new panel'. In the 'Discover Panels' menu, your second WaveBoard should be shown now, otherwise add it manually.

Now you should have 16 channels of control over the 2 WaveBoards.

Setup - Zoom OSC with XP24

Zoom OSC with XP24:

We have created a Zoom OSC configuration for our XP24 panel. This means that everything is taken care of automatically by Reactor.

By standard it's set up to auto populate, meaning that as users join the call they will be assigned a button. From there you have full individual control. You will have settings like, toggle mute and video, and more advanced settings like if the attendee is in spotlight or pinned. And all of these settings is right at your fingertips!

We have made it easy to change settings for all your attendees by making dynamic user commands.

  • Reset all
    This button resets all the attendee buttons.

  • From first
    This button resets all the attendee buttons, and populates them randomly from the beginning.
