Communications Settings
NOTE: Some settings and options require additional charts or hardware.
Select Settings > Communications.
Serial Port: Sets the input/output format for the serial port to use when connecting the chartplotter to
external NMEA devices, computers, or other Garmin devices. The Garmin Data Transfer option is used when
connecting to a computer. The NMEA Standard option is used when connecting to a DSC VHF radio. The
NMEA High Speed is used when connecting to an AIS VHF radio.
NMEA 0183 Setup: Sets the NMEA 0183 sentences the chartplotter transmits, how many digits to the right of
the decimal point are transmitted in a NMEA output, and how waypoints are identified (
).
NMEA 2000 Setup: Allows you to view and label the devices on the NMEA 2000 network (
).
Marine Network: Allows you to view the devices with which you are sharing maps, sonar, or radar. Not available
on all chartplotter models.
NOTE: You can only view networked data on a model that supports that data. For example, you cannot view
networked radar on model that does not support radar.
Wireless Devices: Allows you set up wireless devices (
Setting Up the Wi‑Fi Wireless Network, page 106
). Not
available on all models.
Wi-Fi Network: Allows you set up the Wi‑Fi network (
Setting Up the Wi‑Fi Wireless Network, page 106
).
NMEA 0183
The chartplotters support the NMEA 0183 standard, which is used to connect various NMEA 0183 devices, such
as VHF radios, NMEA instruments, autopilots, wind sensors, and heading sensors.
To connect the chartplotter to optional NMEA 0183 devices, see the chartplotter installation instructions.
The approved NMEA 0183 sentences for the chartplotter are GPAPB, GPBOD, GPBWC, GPGGA, GPGLL, GPGSA,
GPGSV, GPRMB, GPRMC, GPRTE, GPVTG, GPWPL, GPXTE, and Garmin proprietary sentences PGRME, PGRMM,
and PGRMZ.
This chartplotter also includes support for the WPL sentence, DSC, and sonar NMEA 0183 input with support
for the DPT (depth) or DBT, MTW (water temperature), and VHW (water temperature, speed, and heading)
sentences.
NMEA 0183 Settings
Select Settings > Communications > NMEA 0183 Setup.
Sounder: Enables NMEA 0183 output sentences for the sounder (if applicable).
Route: Enables NMEA 0183 output sentences for routes.
System: Enables NMEA 0183 output sentences for system information.
Garmin: Enables NMEA 0183 output sentences for Garmin proprietary sentences.
Posn Precision: Adjusts the number of digits to the right of the decimal point for transmission of NMEA output.
XTE Precision: Adjusts the number of digits to the right of the decimal point for NMEA crosstalk error output.
Waypoint IDs: Sets the device to transmit waypoint names or numbers via NMEA 0183 while navigating. Using
numbers may resolve compatibility issues with older NMEA 0183 autopilots.
Diagnostics: Displays NMEA 0183 diagnostic information.
Defaults: Restores the NMEA 0183 settings to the original factory defaults.
NMEA 2000 Settings
Select Settings > Communications > NMEA 2000 Setup.
Device List: Displays the devices connected to the network and allows you to set options for some transducers
connected using the NMEA 2000 network.
Label Devices: Changes the labels for available connected devices.
