Hello Mark,
I use two Moto's GM300 as a repeater thats work
great on a ARCOM RC210 controller. They will also work great on the app_rpt
program, which is a excelent confirguration to use. I will be configuring my two
GM300 shortly to finally take advantage of the full duplex system
offered by the app_rpt program/hardware. As far as your 6 pin din some do
not deliver enough audio on the output. So It depends on the radio in use. Most
likely when in use you would use 1200 bps.
The GM300 has 16 pins and depending if you
have the 8 or 16 channel the more pins are programmble for what signals you need
to connect up the app_rpt program that run the hardware.
