P1 Charge +10.1V
S1 Line in
S2 Line out
S3 Line GND
S4 DCD gray
S5 TX orange
S6 RX yellow
S7 DTR blue -> (on the programming cable this is also connected to DSR)
S8 RTS green
S9 CTS brown
S10 x
S11 x
S12 x
S13 x
S14 GND black
S15 x
S16 Power out
P2 Charge GND
All pins use pullups and 3.3V
According to the manual the serial signals are inverted.
This pinout is from
Data Interface User Guide (MOD-14-1758) which I did find in one of the RM2 uploads in this forum. I verified it with my own cable.
In
this post it seems to me, that some of the pins (e.g. DCD) are mixed up. But I don't think this is much of an issue, since I doubt that these pins are used in many applications.
It seems that one of the pins serves as Accessory Identifier (ACC_ID) once connected via resistor to GND. I guess it can activate the line in and out.

1 GND
2 Mic -
3 V Battery (7.4V)
4 Mic +
5 ?
6 Speaker +
7 Speaker -
8 Digital Softkey (radio uses a pullup to Vcc, if it is on)
9 Power out (3.3V)
10 PTT (0R to GND is PTT press, 10k to GND is emergency button press)
11 ACC_ID (33k to GND signals standard microphone)
The Sepura standard microphone uses the pin 10 and pin 11. The advanced microphone (the one with the three buttons more) uses 8 and 9 instead, because it uses a PIC16F688 microcontroller to convert the button presses to a digital signal.
There are some pictures on
this German site.
For the STP8X (ATEX) the pinout can be found in
this post.
