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! 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.
