Chapter 9. Connector pinouts

9.1 Modular DCM units

PORT A and B

This is a standard 10-pin mil-spec socket (02E-12-10S). The pinout is such that the port can be connected to the serial output of a DM24 digitizer using a straight-through cable.

Pin	Function
A	Power 0 V
B	Power +10 to +35 V
C	RS232 RTS
D	RS232 CTS
E	RS232 DTR
F	RS232 DSR
G	RS232 ground
H	RS232 CD
J	RS232 transmit
K	RS232 receive

DATA OUT port

This is a standard 10-pin mil-spec plug (02E-12-10P). The pinout is the same as the serial output of a DM24 digitizer, allowing you to insert a DCM into a pre-existing installation and maintain connectivity.

Pin	Function
A	Power 0 V
B	Power +10 to +35 V
C	RS232 CTS
D	RS232 RTS
E	RS232 DTR
F	RS232 DSR
G	RS232 ground
H	RS232 CD
J	RS232 receive
K	RS232 transmit

USB connector

This is a standard 6-pin mil-spec socket (02E-10-06S).

Pin	Function
A	+5 V DC (USB Type A pin 1)
B	Data –ve (USB Type A pin 2)
C	Data +ve (USB Type A pin 3)
D	0 V (USB Type A pin 4)
E	Shielding
F	Switched power +10 to +35 V

NETWORK connector

This is a standard 6-pin mil-spec plug (02E-10-06P).

Pin	Function
B	Data transmit +ve (RJ45 pin 1)
C	Data receive +ve (RJ45 pin 3)
E	Data receive –ve (RJ45 pin 6)
F	Data transmit –ve (RJ45 pin 2)

9.2 Integrated DCM units

DM/AM module output

This is a standard 32-pin mil-spec plug (02E-18-32P).

Pin	Function
D	Power +10 to +30 V
E	Power 0 V
J	Data transmit +ve
K	Data transmit –ve
L	Data receive +ve
M	Data receive –ve
R	AM console receive
S	AM console transmit
T	AM console ground
U	Tamper switch 5
V	GPS 1pps signal
W	GPS RS232 transmit
X	GPS RS232 receive
Y	GPS RS232 ground
Z	DM console transmit
a	DM console receive
b	DM console ground
c	Tamper switch 0
d	Tamper switch 1
e	Data ground
f	Tamper switch ground
g	Tamper switch 2
h	Tamper switch 3
j	Tamper switch 4
