SKAARHOJ GPIO Control Made Easy

Setting up an I/O device have never been this flexible. Connect and control anything from your tally lamps, trigger ATEM switcher routines, control a HyperDeck, change Scopes on a SmartScope Duo and route inputs/outputs on a VideoHub. Defining parameters – single or multiple - for inputs/outputs is extremely fast, thanks to the drop-down menu structure in UniSketch OS. Connect and control up to 8 devices at the same time!

Broadcast I/O easy control or integration with existing systems

The GPIO controller let you control anything from your tally lamps, a foot switch over ethernet or integration with existing systems such as CCUs, video routing and other video switchers or video infrastructure units. There are almost endless possibilities.

The general-purpose I/O controllers offer 8/16 inputs and 8/16 outputs, all electrically separated with quality relays and optocouplers. GPO is implemented with relays shorting to GND. GPI implemented with optical isolators shorted to GND.

Please notice: SKAARHOJ Controllers with GPI inputs accept open collector and relay outputs (pulled to GND). The default HD15 tally connector on the TriCaster TC1 does not provide a direct working signal to the ETH-GPI Link. Converting the 5V potential to GND is needed.
 

The DB25 connector configuration is similar to the Blackmagic Design GPI & Tally Interface. If you fancy a breakout board for the DB25 connector with Phoenix connectors then have a look at the Breakout Board.

Device Settings

The ETH-GPI Link runs UniSketch OS which allows you to configure the device for multiple hardware devices such as the ATEM Switcher, HyperDeck, SmartScopes, VideoHubs, AJA KUMO Routers, vMix and more - see the entire list. You can even configure the unit to control multiple hardware devices at the same time! The microprocessor (SKAARDUINO Due) inside the ETH-GPI Link allows connections to a maximum number of 8 devices.

UniSketch OS Config Page configure GPI & GPO

A number of default configurations exists for the ETH-GPI Link utilizing various Device Cores. Use any of these if they suit your application or use them as inspiration to build your configuration. As we develop more Device Cores additional default configurations will be added to the ETH-GPI Link.

By entering the UniSketch OS config page for a specific default configuration this is the overview you are presented with. By pressing on either of the In/Out pins the menu will jump to that particular input/output setting. Here you can define actions for almost any of the ATEM parameters, control HyperDeck, SmartScope and VideoHub and more hardware devices - see the overview on Device Cores.

To learn the specific behaviour for GPI and GPO for each parameter we refer to the specific Device Core manuals.

By selecting a action, for instance a ATEM parameter to control, a number of options will appear such as selecting 1ME or 2ME, particular sources and default, Hold Down, Toggle or Cycle behaviour.
