Welcome to the SKAARHOJ support page. Here you will find the latest instruction manuals with all the information you need to get started.

We keep our manuals and other relevant support files in the GitHub Repository: Support

If you are looking to access the Config Page of your UniSketch OS based device or want to alter settings such as IP address go to the: Firmware Updater Application but remember to read the "Installation and Operation Manual".

As our controllers are generic in what they can do we don´t have specific manuals for each product. We recommend starting with the "Installation and Operation Manual" and then the manuals for the relevant Device Cores. If you are utilizing Device Cores with PTZ Camera please also have a look in the "PTZ Manual".

Device Cores:


JVC Connected Cam Studio RCP:

Sony BRC-X400:



For latest updates on Device Cores head over to the Device Core Page. We do our best to keep the manuals for the various action parameters updated, but you can always go to and modify a configuration to see the latest implementations.

If you are controlling a ATEM Switcher with a UniSketch based device we currently support ATEM Software Control 8.1. Please see the ATEM Device Core manual for the latest updates.

With the release of Blackmagic Camera Setup 6.9.2 the 3G SDI Shield/Fiber System compatibility have been resolved
Compatibility for CCU Control, Tally and Program Return Feed for the BMD 3G-SDI Arduino Shield

Note for SKAARHOJ controllers with Blackmagic 3G-SDI Arduino Shields and Studio Fiber Converter/Camera Fiber Converter:


Please Notice: Previously the Studio Fiber Converter/Camera Fiber Converter was not compatible with their own 3G-SDI shield which is the component we use inside the RCPs and other products. However with the release of Blackmagic Camera Setup 6.9.2 (April 2020) this have now been resolved.

We have tested Blackmagics fiber converter products in general to work with SDI output. This includes the Mini Converter, ATEM Camera Converter, ATEM Studio Converter and ATEM Talkback Converter 4K and now also the Studio Fiber Converter/Camera Fiber Converter.

Embedding CCU data on the the 3G-SDI return feed

For controllers with the SDI option, you find a 3G-SDI in and out BNC plug. Route the return feed to the camera through this connection to insert CCU data on the signal.

If you use the Blacmagic 3G-SDI Arduino Shield for camera control the following outputs are supported: 720p50, 720p59.94, 720p60, 1080i50, 1080i59.94, 1080i60, 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94 and 1080p60, but the camera doesn´t have to be running the same video format as the program input, so you can use cameras in Ultra HD while the camera protocol is sent over HD signal to the camera.

BMD Camera Support

SKAARHOJ units with the SDI option controls any Blackmagic camera that supports CCU over the return SDI feed. The CCU data is inserted on the SDI return feed.
