Blackmagic Design GPI and Tally Interface

Hardware GPI and tally interface for broadcast switcher control

The Blackmagic Design GPI and Tally Interface is a hardware control device designed to integrate external equipment with broadcast switchers. It enables GPI triggering and tally signal distribution, allowing studios, live production environments, and broadcast facilities to synchronize switcher operations with external systems such as automation equipment, lighting systems, and tally indicators.

The unit provides eight opto-isolated GPI inputs and eight relay outputs that can be used to trigger switching functions or other production events. It also includes 8-channel contact closure tally outputs, allowing tally signals from compatible switchers to drive external tally lights or monitoring systems used in professional studio environments.

Designed for broadcast reliability, the interface connects via USB to compatible Blackmagic Design switchers and production systems. This allows external devices to trigger switcher actions or receive tally signals, helping production teams coordinate camera status indicators and automation cues during live productions.

The compact hardware design makes it suitable for installation in broadcast racks, control rooms, or live production setups where integration between production equipment and external control systems is required.
