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. Although this standard is 50 times faster than NMEA 0183, it is not intended to support high-bandwidth applications such as video. NMEA 2000® 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. IEC 61162-3 references NMEA 2000®. NMEA 2000® is a registered Trademark of the National Marine Electronics Association.

NMEA 2000 Certification Tool and Product Certification
All NMEA 2000 products must be certified based on the NMEA 2000 License Agreement. This can be done by the manufacturer or by a third party. The NMEA 2000 Certification tool can assist manufacturers through NMEA 2000 development and also generates a mandatory encrypted certification file which is sent to NMEA for validation. After validation, by NMEA certification is granted.
