What is the difference between NMEA 2000 and NMEA 0183?

NMEA, the National Marine Electronics Association (NMEA), is a US-based marine electronics trade organization responsible for developing standards for communication between marine electronics. Currently there are two main standards: NMEA0183 and NMEA2000.

NMEA 0183 operates using the RS232/RS422 one-to-one connection method, where multiple devices are "connected together" with the help of multiplexers and buffers. NMEA 2000 uses CAN with a trunk/branch cable network system where all the devices on the network communicate with each other.



NMEA 2000 simplifies connectivity - the NMEA 2000 backbone is a single trunk cable to which T-connectors, network cables and terminating resistors are simply screwed. Unlike connecting NMEA 0183 open cable ends.



Thus, NMEA allows different instruments and marine electronics to communicate with each other. NMEA0183 is an old standard that is being replaced by a new standard called NMEA2000. However, NMEA0183 is still the main standard.



NMEA0183 is the most common standard on board, almost every marine electronic system has a NMEA0183 input and output. Most new marine electronics are now using the new NMEA2000 standard, but almost all of them maintain NMEA0183 connectivity.
