NMEA2000® Standard

Standard for Serial-Data Networking of Marine Electronic Devices

NMEA Interface Standards are intended to serve the public interest by facilitating interconnection and interchangeability of equipment digital data, minimizing misunderstanding and confusion between manufacturer's equipment and provide safe and reliable communication for the boat and boater.

NMEA2000® standard contains the requirements of a serial data communications network to inter-connect marine electronic equipment on vessels. The standard describes a low-cost moderate capacity bi-directional, multi-transmitter/multi-receiver instrument network to interconnect marine electronic devices.

It is multi-master and self configuring, and there is no central network controller. Equipment designed to this standard will have the ability to share data, including commands and status with other compatible equipment over a single channel. It is based on CAN (Controller Area Network). All NMEA 2000® products must be certified by NMEA. Although this standard is 50 times faster than NMEA 0183, it is not intended to support high-bandwidth applications such as video.

NMEA2000® represents the cumulative efforts of the NMEA 2000® Standards Committee, a committee of multi-national industry and government subject matter experts and professionals who have contributed time and expertise to the development this standard.

The "NMEA Network Message Database" is the brand name of the IP of NMEA 2000.  When purchasing the NMEA 2000 Standard, along with the standard documents, you will receive the "Message Database" in a PDF report.
