Hi!
I have MCS2000 and i use it for Echolink, but connection with my PC i make over RG45. I dont find PTT in 25PIN-connector?
How can i programming station and connect my interface over 25-pin connector.
Now i can't speak with microphon and audio out i must control from station not in PC.

My station M01KHM9PW5_N 136-174 MHz 1-25 Watts Model II, 1x14 digits 25/20/12.5 kHz 160

... and where i can find Service Manual for it?

Look on Batlabs.com under model specific for the MCS2k and under Programming for the interface cable.

I do know that the PTT and type of audio input have to be set in the RSS to function on the 25 pin connector.

Here's a list of 'common' pins for you might be using for the MCS2000:

Pin 1 - Speaker +
Pin 3 - Speaker -
Pin 4 - digital ground
Pin 7 - HUB/Monitor - radio will enter monitor mode when this line is not connected to ground (RSS programmable)
Pin 8 - Car radio mute (RSS programmable)
Pin 9 - Emergency - must be connected to ground. Usually jumpered to Pin 4
Pin 10 - analog ground
Pin 11 - filtered audio out
Pin 14 - Switched B+
Pin 15 - ignition sense (RSS programmable)
Pin 21 - PTT (active low)
Pin 23 - External Mic In
