can anyone give me the programming info for the programmable 16 accy pins to make the CM300 work with the CS-900 in simplex mode only. We are going to be using PR400 Radio's with DTMF

The pinouts for the CM300 are the same as you'd find in most Motorola 16-pin radio models. Some of the more common ones:

Pin 2 - external mic audio
Pin 3 - External PTT
Pin 5 - flat TX audio
Pin 7 - Ground
Pin 8 - COR (usually programmable)
Pin 11 - Flat or filtered RX audio (either jumper or programmable to choose)

Most other pins are programmable for various different functions, in particular 4, 6, 9, 12, 14
