NMEA 2000® Interface Standard
Standard for Serial-Data Networking of Marine Electronic Devices
The NMEA 2000® 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.
New Release (April 2022) NMEA 2000® Version 3.000
NMEA has released a new and improved version of the NMEA 2000 Standard, Version 3.000. This new version, when implemented by manufacturers, will yield better product interoperability through improved requirements in the NMEA 2000 Main Document language, new PGNs, and upgraded Certification Tool. Nineteen new NMEA 2000 Network Messages (PGNs) have been added to Appendix B, including a full suite of Lighting PGNs, which manufacturers can use to implement standard lighting controls via NMEA 2000-certified lighting control boxes and MFDs. Other new PGNs include a Linear Actuator PGN for control of outboard engine jack plates and davits, Bow Thruster PGNs, Anchor Windlass PGNs, Elevator PGNs, and a Vessel Acceleration PGN to aid in crash detection. All amendments and corrigenda from the prior release of the NMEA 2000 standard have been rolled into this new version. Application notes on select new PGNs and their implementation have been added to Appendix D of the standard.
A vastly improved NMEA 2000 certification hardware & software tool has also been released. This new release addresses the majority of the upgrade suggestions from manufacturers over the past several years and includes test automation support to make automatic regression testing a reality. Manufacturers are required to certify new products to the updated standard within 18 months, although the NMEA is encouraging them to do so before the August 2023 deadline. NMEA is also urging manufacturers to update their current products’ firmware to support the new PGNs in this the latest edition. New NMEA 2000 customers now have an easy way to purchase specific parts of the standard based on their specific development plan.
