VRS750 Pinout Needed

Post by billforbush »

If anyone on the board has a VRS750 service manual, I would really appreciate the pinout for the control cable. Thank you very much.

Wow,

Is this correct? With that you could use a parallel printer extension cable. Not many Motorola radio applications use a M-F 1-1 cable.

Very easy if indeed true.
