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.
