We're attempting to set up a repeater using 16 channel GM300's and an
external controller (a CAT 1000).
We've done this before twice, but seem to be stumped this time because
we can't get either the receiver radio or link radio to produce the
right voltage swing the controller is looking for
It depends a bit on which logic board you have, but
pin 8 on the accessory connector is either an
open-collector transistor which requires an external
pull-up resistor, or a logic line with a 4.7k resistor
to +5V in the radio.
You then have to program the radio for COR on pin 8,
and choose
You might want to try pin 14 instead of pin 8.
I just got done interfacing a controller to a GM300 and couldn't get pin 8
to work but pin 14 did.
The RSS indicates both pin 8 and 14 are PL/DPL/CSQ detect but only pin 14
seems to function properly.
