RX connector, pins 1 and 7
An independent receiver may function as a control receiver and
have command priority over other command channels in the
system (repeater receiver and phone). The control receiver audio
may connect to the Control Receiver connector pin 7 and should
be in the range of .5 to 2.5 volts peak-to-peak.
The COS signal should connect to the Control Receiver connec­
tor pin
1. The COS may be high true or low true. DIP switch 3
should be set based on its logic sense,.,. ON for high true, OFF
for low true. IT a control receiver is not connected, DIP switch 3
must
be ON.
For greater security, a
crcss
decode signal from the control
receiver can replace the COS signal.
crcss
would need to be
transmitted on the control channel to activate the control receiver
function.
