Default Hytera PD78x pinouts/wiring diagrams

Hi all,

Haven't seen any post related to my question, so I decided to create one.

I own a Hytera PD785 and I'm looking for a headset and PTT solution. I also own a nacre quietpro, but it came with a Motorola Xts cable. What I want to do is to modify the cable, taking out the Motorola contact and attaching a Hytera x55 or Hytera H6 contact (the one meant to be used for audio accessories with the PD785).

The problem is that I can't find the pinouts for the Hytera plug. Any ideas are welcome.

Alternatively, is there any adapter that would convert from Kenwood K1 to Hytera x55/H6 (I have a Kenwood cable for the quietpro I can use)?

Thanks in advance for any help I might get!

Default Hytera PD-78x Portable connector

Since no one has replied and since I have had the same question, here's what I know:
The Hytera System Planner includes a diagram of the connector which mates with the portable and the Service Manual includes a table listing the pin/signal assignments. I've attached both to the reply. I hope this helps. Good Luck!

Thanks! That's exactly what I was looking for!
Been through the technical manual myself and found the table for the 16pin, but was not 100% sure, since there was no schematic diagram of the connector.

Thanks again Romans!
