Chapter 7. Connector pin-outs

7.1 DATA

This is a standard 10-pin “mil-spec” plug, conforming to MIL‑DTL‑26482 (formerly MIL‑C‑26482). A typical part-number is 02E-12-10P although the initial “02E” varies with manufacturer.

Suitable mating connectors have part-numbers like ***-12-10S and are available from Amphenol, ITT Cannon and other manufacturers.

The pin-out is the same as the serial output of a CMG-DM24 digitiser and any GSL digital instrument, allowing you to insert an instrument with an embedded CMG-EAM into a pre-existing installation and maintain connectivity.

Pin	Function
A	Power input, 0 V
B	Power input, +10 to +35 V
C	RS232 CTS
D	RS232 RTS
E	Not connected
F	Not connected
G	RS232 ground
H	Not connected
J	RS232 receive
K	RS232 transmit

Wiring details for the compatible socket, ***-12-10S, as seen from the cable end (i.e. during assembly).

7.2 GPS

This is a standard 10-pin “mil-spec” plug, conforming to MIL‑DTL‑26482 (formerly MIL‑C‑26482). A typical part-number is 02E‑12‑10P although the initial “02E” varies with manufacturer.

Suitable mating connectors have part-numbers like ***‑12‑10S and are available from Amphenol, ITT Cannon and other manufacturers.

This pin-out is the same as the GPS input of a DM24 digitizer.

Pin	Function
A	Power 0 V
B	Power +12 V
C	1pps signal
D	not connected
E	Console TxD
F	Console RxD
G	GPS ground
H	Console ground
J	RS232 transmit to GPS
K	RS232 receive from GPS

Wiring details for the compatible socket, ***‑12‑10S, as seen from the cable end (i.e. during assembly).

7.3 Analogue connector

This is a standard 19-pin “mil-spec” socket, conforming to MIL‑DTL‑26482 (formerly MIL‑C‑26482). A typical part-number is 02E‑14‑19S although the initial “02E” varies with manufacturer.

Suitable mating connectors have part-numbers like ***‑14‑19P and are available from Amphenol, ITT Cannon and other manufacturers.
