What is the difference between NMEA 2000 and NMEA 0183?
NMEA 0183 operates on a 1-to-1 connection method using RS232/RS422, where multiplexers and buffers are required to connect multiple devices ‘together’. NMEA 2000 uses CAN with a backbone / drop cable network system, where all devices on the network talk to one another.
NMEA 2000 simplifies the connection – The NMEA 2000 backbone is a single trunk cable to which the appropriate T-pieces, network cables and terminators can simply screw onto. Unlike connecting NMEA 0183 open cable ends.
Using NMEA 2000 gateways, like the NGW-1, allows compatibility between the two networks
