2. NMEA 2000
NMEA 2000 network runs at 250 kbps and allows up to 60 physical devices to be connected. Unlike NMEA
0183, there are no “talkers” and “listeners”. All devices can “talk” and all devices receive all messages. Many
electronic manufacturers presented “branded” versions of NMEA 2000. Raymarine SeaTalk NG, Simrad
SimNet, FurunoCAN differ only in the type of connectors used. However, in recent years manufacturers
have been moving to NMEA 2000 connectors.
