Marine plug-and-play communications standard
NMEA 2000
NMEA 2000, abbreviated to NMEA2k or N2K and standardized as IEC 61162-3, is a plug-and-play communications standard used for connecting marine sensors and display units within ships and boats. The standard is maintained by the National Marine Electronics Association (NMEA). NMEA is often confused with the NEMA (National Electrical Manufacturers Association) though they are unrelated. Communication runs at 250 kilobits-per-second and allows any sensor to talk to any display unit or other device compatible with NMEA 2000 protocols.
