Author Topic:   Plug Pin Configuration

The other day I was going to bench test a combination GPS receiver and finder unit recently purchased. The power and data cord was missing. Have an assortment of pin and socket jumper wires made up for troubleshooting and found the size needed to safely power up the unit using my power supply. The install manual gave pin numbers and wire colors but the circular connector itself had no pin ID [numbers]. The manual lacked an illustration of the plug identifying pin location. Cable now on order. Does NMEA have standard plug and pin configurations?

There is a NMEA-2000 standard for backbone wiring and for drop cables.

Manufacturers of marine electronics do not seem to have a standard for power connectors and wiring of NMEA data on multi-conductor cables. They all seem to use different color codes and connectors.

What unit? Probably somebody here has one and can tell you
which pins are which.

Thanks for the idea. I have a cable on order so will just wait for it. Found the connector manufacturer and their info shows the pin arrangements but not the pin numbers. The Navman manual tells me pin 1 is ground and pin 5 is power. There is a small raised nub molded into the connector pin side that's probably to indicate pin 1 and probably standard clockwise numbering from their. But don't want to assume this an possibly fry the unit.

Also shot off an email to Northstar and will see how their support is.

Nothstar was quick to respond with good info. Also sent email to some folks that sell the connectors, they were able to supply a drawing.

Powered up the new/old Navman 6600 I purchased last year, popped in a C-Map and must say, impressed with this new to me technology.

These LTW connectors may be of interest to some needing disconnects for their wiring projects. Their larger ones will carry more amps.
