Creating a Basic NMEA 2000 Network If your boat does not already have an existing NMEA 2000 network installed, you will need to create a basic NMEA 2000 network. For more information on NMEA 2000, visit www.garmin.com. To create a basic NMEA 2000 network 1. Connect the three included T-connectors together by their sides. 2. Connect the appropriate terminators to each end of the combined T-connectors. 3. Wire the included NMEA 2000 power cable to a 12 Vdc power source through a switch. Connect to the ignition switch for the boat if possible. 4. Connect the NMEA 2000 power cable to the top of one of the T-connectors. 5. Route and connect the included NMEA 2000 drop cables from the GPS 17x and from the GPSMAP 4000/5000 series chartplotter to the tops of the other T-connectors.

The chartplotter must also be connected to power or it will not function. See page 9. Note: One GPS antenna will provide position data for every device on the NMEA 2000 network. Do not connect multiple GPS antennas if you are using multiple chartplotters. GPSMAP 4000/5000 Series Installation Instructions 11
