The term marine electronics is used for areas such as
Marine electronics devices are
The electronics devices communicate by using a protocol defined by NMEA. NMEA has two standards available
NMEA 0183 is based on a serial communication network. NMEA 2000 is a Controller-area network based technology.
In recent years, the International Electrotechnical Commission (IEC) has created a new standards suite for "Digital interfaces for navigational equipment within a ship". This is known as IEC 61162 and included NMEA 0183, NMEA 2000 and LWE.
Also different suppliers of marine electronics have their own communications protocol
