NAVnet NMEA2000 (CAN Bus) Network

This document describes the Furuno CAN bus and shows how to create Furuno CAN bus
networks and how to install Furuno CAN bus devices.

What is Furuno CAN bus?

Furuno CAN bus devices comply with NMEA 2000 physical and protocol standards, but these
devices can be installed in a slightly different way from the NMEA2000 standard to make a
network creation easier.

NMEA 2000

NMEA 2000 is a combined electrical and data specification for a marine data network for
communication between marine electronic devices such as depth finders, chartplotters, navigation
instruments, engines, tank level sensors and GPS receivers. NMEA 2000, a successor to the NMEA
0183 standard, connects devices using CAN (Controller Area Network) technology originally developed
for the automotive industry. CAN based networks were developed to function in electrically noisy
environments.

NMEA 2000 vs. NMEA 0183

NMEA 2000 is a serial data “network” operating at 250k bps and NMEA 0183 is a serial data “interface”
operating at 4.8k bps. NMEA 2000 networks allows multiple electric devices to be connected together
on a common channel for the purpose of easily sharing information.
