Blackmagic Design GPI and Tally Interface

Add tally to your ATEM switcher with Blackmagic Design’s GPI and Tally Interface! With 8 contact closure tally outputs, you can send a tally signal to your cameras, replay machines and monitors so everyone knows which camera is ‘on-air’! If you need more tally outputs, simply connect multiple GPI and Tally Interfaces together because it connects via Ethernet to your ATEM production switcher.

Eight tally signals
The GPI and Tally Interface by Blackmagic Design is an Ethernet device which provides eight mechanical relay contacts closures to ground that can be used for tally. Tally signals are sent from the Ethernet port of your ATEM switcher to a GPI and Tally Interface on the same network as the switcher. By following the wiring guide on the back of the GPI and Tally Interface, a breakout cable can be connected to video equipment that supports contact closure tally signals, such as Blackmagic Design SmartView Duo and SmartView HD.

For all ATEM switchers
Up to 8 tally receiving devices can be supported with a single GPI and Tally Interface. Only one GPI and Tally Interface unit is needed when used with an ATEM 1 M/E Production Switcher, ATEM Production Studio 4K or an ATEM Television Studio. Two units of GPI and Tally Interface are needed when used with the 16 inputs of ATEM 2 M/E Production Switcher. The GPI inputs are optical isolators which are triggered by connection to ground with a maximum of 5V at 14mA. The tally outputs are mechanical relay contact closures to ground with a maximum of 30V at 1A.
