GPI and Tally interface 8 outputs - Blackmagic Design BLM-SWTALGPI8

Blackmagic Design GPI and Tally Interface adds tally functionality to an ATEM switcher and sends the tally signal to cameras, replay machines and monitors, making it clear which camera is “On Air”. It provides 8 relay contact outputs. When additional tally outputs are required, multiple interfaces can be linked together via Ethernet to the ATEM switcher.

The Ethernet connection is 10/100 BaseT with loop-through for connecting other Ethernet-enabled equipment. A 25-pin D-type contact-closure connector provides 8 opto-isolated inputs and 8 relay contact-closure outputs. The inputs use optical isolators triggered by a connection to ground, with a maximum of 5 V at 14 mA. The outputs use mechanical relay contact closure to ground and support a maximum of 30 V at 1 A. Configuration and hardware updates are handled through 1 high-speed USB 2.0 computer interface.
