NMEA 0183 and NMEA 2000
The GPSMAP 4000 and GPSMAP 5000 series chartplotters can accept data from NMEA 0183
compliant devices and also from certain NMEA 2000 devices connected to an existing NMEA 2000
network on your boat.
NMEA 0183
The NMEA 0183 data cable included with the GPSMAP 4000 and GPSMAP 5000 series
chartplotters support the NMEA 0183 standard, which is used to wire various NMEA 0183-
compliant devices such as VHF radios, NMEA instruments, autopilots, wind sensors, or heading
sensors.
The GPSMAP 4000 and GPSMAP 5000 series chartplotters can receive data from up to four NMEA
0183-compliant devices and send GPS data to up to six NMEA 0183-compliant devices.
To wire a GPSMAP 4000 or GPSMAP 5000 series chartplotter to optional NMEA 0183-compliant
devices, see the GPSMAP 4000/5000 Series Installation Instructions.
Approved NMEA 0183 sentences:
GPBWC, GPRMC, GPGGA, GPGSA, GPGSV, GPGLL, GPBOD, GPRMB, GPRTE, GPVTG,
GPWPL, GPXTE, and Garmin proprietary sentences—PGRME, PGRMM, and PGRMZ.
This unit also includes support for the WPL sentence, DSC, and sonar NMEA 0183 input with
support for the DPT (depth) or DBT, MTW (water temp), and VHW (water temp, speed, and
heading) sentences.
NOTE: To congure how the unit manages these NMEA 0183 sentences, see page 30.
NMEA 2000
The GPSMAP 4000 and GPSMAP 5000 series chartplotters are NMEA 2000 certied and can
receive data from a NMEA 2000 network installed on the boat.
To connect a GPSMAP 4000 or GPSMAP 5000 series chartplotter to an existing NMEA 2000
network and to see a list of supported NMEA 2000 PGN numbers, see the GPSMAP 4000/5000
Series Installation Instructions.
All GPSMAP 4000 and GPSMAP 5000 series chartplotters are NMEA 2000
certied.
