NMEA

The National Marine Electronics Association (NMEA) has defined communication standards for maritime electronic equipment. The EK80 Wide band scientific echo sounder supports these standards for communication with external sensors and peripheral systems.

The most common standard is NMEA 0183. The National Marine Electronics Association describes it as follows:

The NMEA 0183 Interface Standard defines electrical signal requirements, data transmission protocol and time, and specific sentence formats for a 4800-baud serial data bus. Each bus can have only one talker but many listeners.
