NMEA 2000 Network Fundamentals
This technical reference provides basic NMEA 2000 component identification (NMEA 2000 Components,
page 2), basic NMEA 2000 network-building instructions (NMEA 2000 Network Planning and Construction,
page 4), and a list of NMEA 2000 data that may be used by some Garmin NMEA 2000 certified devices
(General NMEA 2000 Data Types, page 12).
What is NMEA 2000?
NMEA 2000 is a plug-and-play communications standard used for connecting marine sensors and display
devices within ships and boats, and is considered the successor to the NMEA
®
0183 serial data bus standard.
You can learn more about NMEA 2000 and purchase the NMEA 2000 standard documentation at nmea.org
/content/STANDARDS/NMEA_2000.
Garmin uses NMEA 2000 micro connectors on devices, sensors, and T-connectors that are compatible with
other NMEA 2000 micro connectors, cables, and NMEA 2000 compatible devices.
