Item description 12 vdc power source wiring harness nmea 0183 compliant device item garmin wire function garmin wire color nmea 0183 device wire function power red power ground black data ground tx blue. Nmea 0183 wiring diagram the following wiring diagram is an example of what you may encounter when wiring your nmea 0183 device to the gpsmap 400500 gpsmap 600 gpsmap 700 gpsmap 40005000 or gpsmap 60007000. There are multiple versions of the nmea 0183 specification in use in the marine industry. Older gamin units older garmin units like the 3000 series or 498 use the black power wire ground as the nmea 0183 transmit and receive negative. Prior to nmea 0183 version 20 including nmea 0180 and nmea 0182 the hardware employed a single ended interface implemented with one signal wire and a common ground based on eia 232. When connecting a nmea 0183 device with only one transmitting tx wire or with only one receiving rx wire the nmea 2000 bus and the nmea 0183 device must be connected to a common ground.
Installing and connecting devices using the nmea 0183 interface standard. Again garmin uses a common negative wire for both power and network so there is only one wire for nmea in and one for nmea out. Every so often we will see other units that do this if you unit does this just connect the tx and rx wires from the unit you are interfacing to the sam. This sounder is capable of both nmea 0183 and nmea 2000 modes of operation however since this tutorial is about nmea 0183 we are limiting our discussion to this connection. This confuses the heck out of people.
