TK-790h Programming Cable KPG-43

[totibross]

I got this TK-790h and got it working after a few hiccups..
I know I should buy the cable to program the radio, but I'm cheap and I would love to know if someone can send me the pin-out diagram.
For what I've seen the 12pin Mic cable has only three connections.

I actually bought the USB version for this cable but it did not work. I have a good understanding on serial ports, so I think somehow the TK does not like this TTL usb connection

So the pin-out to RS-232 9 Pin would be great..

thx

It has been a while but I seem to remember it not only being TTL conversion but also it carries data on one wire, so additional circuitry is required.

The issue is finding the 12 pin microphone connector…
Best thing to do is to buy an old microphone off e-bay and roll your own.

Pin 1 is at the 12 o'clock position, facing the end of the connector, the pin numbering goes around clockwise.

Pin
1 = Switched power
2 = Hook signal input
3 = Microphone Earth
4 = Microphone input
5 = Earth
6 = Transmit Data Output/Receive Data Input
7 = KVL
8 = Serial Data Input/Output for Keypad mic
9 = Mic Backlight control
10 = PTT
11= N/C
12 = Audio output for headset > 2Ω load.


KPG-43UM is the Kenwood USB programming cable.
