2..........RX AF output
3...........Aux COR switch(goes low, 0.1 V with incoming signal). (open
collector.) 100 mA max
4..........Aux PTT input (GND = Transmit) Will not time out
5..........Remote COR disable
6..........Receiver COR out
7.........+5 VDC @ 100 mA max
8.........+13.8 VDC @ 500mA max
9.........Ground
10........CTCSS tone input
11.......CTCSS trigger

Re: Spectrum Communications SCR 77 UHF repeater
You might have asked for a few more opinions before you bought
a specific controller. Replacing the internal controller is
quite a bit more involved versus dealing with just the CW ID'er
function using something like an ID-O-Matic unit.
Do you want to interface the entire controller into the SCR-77
or just replace the CW ID'er function?
Maybe the folks at MCC will/should have the connection information
available?
Our technical replies depend on how you want to interface the
board to the repeater operation. There is a rear panel interface
jack on the SCR-77 for use external controller connections.
