NMEA 2000 stands for National Marine Electronics Association 2000. It is a set of standards developed by the National Marine Electronics Association for data communication among marine electronics devices. The NMEA 2000 standard defines the electrical and data communication protocols used in the network, as well as the data format and message structure used for transmitting data between devices. NMEA 2000 is designed to enable different marine electronics devices, such as GPS units, chartplotters, depth sounders, and marine radios, to communicate with each other and share data in a seamless and standardized manner.
