Blackmagic Design GPI and Tally Interface

Description

This interface adds GPI (General Purpose Interface) and tally control to a Blackmagic production switcher, letting external devices trigger switcher functions or receive tally status. It's used to integrate cameras, lighting or other on-set equipment with a multicam switcher's program and preview bus. Its tally outputs let camera operators see on-air status directly at the camera rather than relying on a separate monitor. It's compatible with Blackmagic ATEM switchers and other GPI/tally-capable equipment. It suits live event, studio and multicam broadcast productions needing tally and external device integration with their switcher.
