GND is the GND of the 2.5mm jack plug, the PC->radio line is the GND of the 3.5mm jack plug’s GND (which is also PTT), the radio->PC line is the middle of the 2.5mm jack plug. 9600bd, max232 needed.

Hello nonoo,

I have a kg-uv6d wouxun ht. Can you kindly guide me on the schematic wiring to my URI-DMK fob USB interface. Its going to be from my programing cable ( wouxun) hack into DB25 pin uri . My purpose is to use this as my mobile radio node portable VOip over my aircard 3G via allstarlink.
Any advice on the pin out including squelch would be appreciated.

Thank you Sir.

Just as a side comment, since I can never keep these schematics straight, these should be read as:

2.5mm Phone:

Sleeve: GND
Ring: Empty
Tip: Audio Out

3.5mm Mic:

Sleeve: PTT
Ring: Mic In
Tip: Empty
