motorola DTMF mic HELP...

[terryr27]

looking for wire schematic for a motorola DTMF mic AARMN4026.....thanx

That's not really a dtmf mic. It's a mic with 15 switch closures and a 10 a pin connector to plug into a CDM mobile so that the mobile knows which dtmf tone to generate.

ok,well i still nee the schematic for this mic,the end was cut off it and i dont got a clue where the end ever went to. any help??

[Bill_G]

It's a standard Moto 8 wire pinout for Maxtrac, M1225, etc for pins 2-9. Pins 1 and 10 were added for the keypad functions in the CDM series. We found jacks, plugs, and crimping tool at Graybar (if I recall correctly) so we could fab extension cables.

The obscure 10 pin jack has been discussed in the past here.

so your saying i need a 10 pin connector? if i understand correctly,the 8 pin will not work?
