The TLC-8d controller is an adapter box the connects to the TriCaster TCXD850's 15 pin tally port and interfaces to either model of our tally lights.
The '850's tally port supports a 'program' tally for the source selected on the program bus of the switcher. The TLC-8d translates this signal to illuminate the red camera operator tally and the 'talent' tally on the TL-2 tally light. The talent tallys can be globally disabled via a jumper in the TLC-8d.
For CCU users the TLC-8d has wet contact closure outputs (5v @20mA) so it can be interfaced with some CCUs tally ports.
What sets the TLC-8d apart from a simple adapter cable is the intercom pass through so you can run both tally and intercom on a single Cat5 cable run. Connect your intercom base station into the xlr on the TLC-8 then connect your beltpacks to the multi-purpose port on the tally lights.
The TLC-8d is also upgradeable to full microprocessor functionality. In the event NewTek releases a software developers kit for the '850 we can upgrade your controller and provide additional features like preview/effects tally and GPI I/O.
