Hello All,
I was wondering if anyone had the pinout for a DTMF CDM Mic.
The CDM Mic's are not backward compatible with the older style GM300 SM120 type radios, I am able to get audio but no DTMF.
I was hoping to be able to rewire the mic so that I would get the DTMF as well.
Any help would be appreciated.
Thank You

The CDM "DTMF" mic is not realy a DTMF mic it is a "keypad" mic.
The mic does not encode the DTMF tones. That is done inside the radio. It is a serial link from the mic to the radio.
You will not be able to use a CDM "keypad" mic on another radio (such as Maxtrac, Gm300) for DTMF operation.
Hope this helps, Alan
