I am trying to hook up a Motorola desk mic (RMN5070A) to the rear accessory connector of a dash mount XTL2500. I have determined the pin locations for GROUND (pin 14), AUX PTT (pin 16), and AUX MIC (pin 23).
On the desk mic connector itself, I have PTT on pin 2, GROUND on pin 5, and MIC_ HI on pin 7.
What I am trying to determine is where on the accessory connector do I connect HUB/KEYFAIL (mic connector pin 9) and GPIO (mic connector pin 10).
NOTE: I do not plan on using the HUB feature.
Thanks for any help,
