Chapter 4. Connector pin-outs

4.1 ELP-0119

4.1.1 GPS Receiver in

This is a standard 10-pin military-specification bayonet 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.

4.1.3 Link

This is a standard ISO 8877 8P8C modular socket (often incorrectly referred to as RJ45).

NMEA inverting output (-)

3

PPS inverting output (-)

This socket accepts ISO 8877 8P8C modular connectors (often called Ethernet “Cat 5/6” connectors or, incorrectly, RJ45 connectors).

Note: If two-pair shielded twisted-pair (STP) cable is being used instead of Cat 5 or Cat 6 cable, one pair should be used for pins 1 and 2 and the other pair should be used for pins 3 and 6. The drain wire and shield should be connected to pin 4.

4.2 ELP-0120

4.2.1 GPS output to digitiser

This is a standard 10-pin military-specification bayonet 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.

This socket accepts ISO 8877 8P8C modular connectors (often called Ethernet “Cat 5/6” connectors or, incorrectly, RJ45 connectors).

Note: If two-pair shielded twisted-pair (STP) cable is being used instead of Cat 5 or Cat 6 cable, one pair should be used for pins 1 and 2 and the other pair should be used for pins 3 and 6. The ground wire should be connected to pin 4.

If the cable has a separate shield and ground wire, the shield should be left disconnected at this end. If there is any chance of the shield end making contact with any other pin, it should be insulated to prevent this.
