Ikan TI-OC-ROS-25A-4 Tally Router for Ross Acuity Switchers, 25-Pin, 4-Camera

Ikan TI-OC-ROS-25A-4 Tally Router for Ross Acuity Switchers, 25-Pin, 4-Camera

The Ikan TI-OC-ROS-25A-4 tally router connects a standalone Ross Acuity switcher directly to as many as four Ikan tally lights. Its dedicated Acuity-pinout cable carries program and preview signals to four RJ45 outputs, providing immediate red, green, and transition cues without software, drivers, custom wiring, or IP configuration.

This four-camera tally interface supports broadcast studios, corporate AV facilities, houses of worship, educational production spaces, and live-event control rooms. Standard Ethernet cable runs simplify tally-light placement around the studio, while the direct DB25 switcher connection streamlines installation. Operators can assign each output to a camera position for an organized multicamera workflow.

The open-collector interface displays red when a camera is on program and green when it is selected for preview. During a mix or wipe, simultaneous red and green signals may produce an amber indication. Ross tally assignments are configured through DashBoard, including the On-Preview bus required for green status. The dedicated two-bank Acuity pinout ensures correct operation with standalone Ross Acuity systems.
