The Raymarine network for connecting current generation Multifunction displays to autopilots, instruments and NMEA2000 networks.
The current marine industry standard. All current Raymarine MFDs are NMEA2000 certified. The standard utilises the CAN (Control Area Network) design developed by Bosch for the automotive market but with messages/sentence appropriate for the marine industry.
A multi-talker, multi-listener approach using serial data at moderate date rates (250kbs).
Under the NMEA standard, manufacturers can use the cable/connector design of their choice so long as it conforms to certain requirements. The topology is a robust terminated backbone/spur design.
