NMEA2000: What is it and Why Do You Need It?


NMEA2000 is a digital language sanctioned by the National Marine Electronics Association(NMEA). It allows marine electronics to talk together. Electronics have the ability to send data and communicate amongst themselves through this standard.

Common examples of marine instrumentation compatible in the NMEA 2000 network include GPS receivers, autopilots, wind instruments, depth sounders, navigation instruments, and nautical chart plotters. The interconnectivity among devices allows systems to use data from another device on the network as input for actions or displays. For example, signal information from a GPS receiver is used to correct course with autopilot; engine RPMs and fuel injection rates calculate how much fuel you have left.

The Backbone of NMEA2000

One of the best features of NMEA 2000 is that all your instruments can be connected through one cable. This eliminates the need for many wires, making installations easier by eliminating bundles of cables underfoot or running up into the cabin.

Imagine it like a high-tech game of telephone. One instrument starts talking to another, that one passes on the message, and so forth until all devices can communicate with each other. This allows you to get real-time info from any device at your fingertips without waiting long periods of time while data is updated or synced.

Why do I need NMEA2000?

NMEA2000 is an important feature that makes integrating and installing electronics much easier. It’s a no-brainer for any boat with electronics on board!
