GPI & Tally interface provides 8 contact closure inputs and 8 contact closure outputs for
connecting to ATEM switchers and Videohub routers. Tallies will be displayed when
connected to an ATEM switcher to indicate their "on-air" status and you can even connect
multiple interfaces together to increase the number of inputs and outputs. GPI and Tally
Interface also works as a Videohub control panel without buttons and LEDs so you can make
your own! Now anyone can connect to Videohub routers to control cross-points!
