Theory of Operation

 

The ST-LCR 2 Logic-Controlled Relay is part of a contact closure cir-
cuit. In the AirPlay MP AFRTS conÞguration, the relay converts a 
momentary closure from a Wegner tone decoder to a steady closure. 
This circuit controls a Grass Valley Group Performer¨ switcher. The 
circuit enables a central, remote network site to send Network Over-
ride and Return to Normal (return to local programming) commands 
to the switcher. The override occurs at the most downstream point of 
the Avid-supplied equipment.

When the Performer switcher receives a Network Override command, 
the switcher output changes to a preselected Network input. The 
switcher stays at this Network position until it receives a Return to 
Normal command.
