Connecting the GPSMAP 4000/5000 Series Chartplotter and the GPS 17x Antenna to Your
nMEA 2000 network
The GPSMAP 4000/5000 series chartplotter is packaged with the necessary NMEA 2000 connectors and cable to either connect the GPSMAP
4000/5000 series chartplotter and GPS 17x antenna to your existing NMEA 2000 network, or to build a basic NMEA 2000 network. For more
information on NMEA 2000, visit www.garmin.com.
Connecting to an Existing nMEA 2000 network
If your boat already has a NMEA 2000 network installed, use the included T-connectors and drop cable to connect the GPSMAP 4000/5000
series chartplotter and GPS 17x antenna to the existing network.
to connect the GPSMAP 4000/5000 series chartplotter and GPS 17x to your existing nMEA 2000 network:
1. Determine the appropriate locations to connect the
GPSMAP 4000/5000 series chartplotter and GPS 17x
to your existing NMEA 2000 backbone.
2. Disconnect one side of a NMEA 2000 T-connector from
the backbone nearest to the location where you want
to connect the chartplotter.
If you need to extend the NMEA 2000 backbone,
connect an appropriate NMEA 2000 backbone
extension cable (not included) to the side of the
T-connector you disconnected.
3. Connect an included T-connector in the NMEA 2000
backbone (for the chartplotter).
4. Route an included drop cable to the chartplotter and
to the top of the T-connector you added to your NMEA
2000 network.
If the included drop cable is not long enough, you can
add a drop cable extension up to 13 ft. (4 m). If more
cable is needed, add an extension to your NMEA 2000
backbone, based on the NMEA 2000 guidelines.
5. Disconnect one side of a NMEA 2000 T-connector from
the backbone nearest to the location where you want
to connect the GPS 17x antenna.
If you need to extend the NMEA 2000 backbone,
connect an appropriate NMEA 2000 backbone
extension cable (not included) to the side of the
T-connector you disconnected.
6. Connect an included T-connector in the NMEA 2000
backbone (for the GPS 17x antenna).
7. Route an included drop cable from the GPS 17x antenna to the top of the T-connector you added to your NMEA 2000 network.
If the included drop cable is not long enough, you can add a drop cable extension up to 13 ft. (4 m). If more cable is needed, add an
extension to your NMEA 2000 backbone, based on the NMEA 2000 guidelines.
If you have an existing NMEA 2000 network on your boat, it should already be connected to power. Do not connect the included NMEA 2000 power cable to
an existing NMEA 2000 network.
NOTES:
• The diagram shows only the NMEA 2000 data connection to the GPSMAP 4000/5000 series chartplotter. The chartplotter must also be
connected to power or it will not function. See
• 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.
