Many manufacturers provide multiplexing and WiFi transceiver functionalities.Įxamples of marine electronics devices to include in a network are GPS receivers, auto pilots, wind instruments, depth sounders, navigation instruments, engine instruments, and nautical chart plotters. NMEA 2000 is meant to be "plug and play" to allow devices made by different manufacturers to communicate with each other. It also allows the instruments to work together, since they share data.
This allows one display unit to show many different types of information. The backbone powers each instrument and relays data among all of the instruments on the network.
Various instruments that meet the NMEA 2000 standard are connected to one central cable, known as a backbone. The protocol is used to create a network of electronic devices, mainly marine instruments, on a boat or vessel. Raymarine SeaTalk 2, Raymarine SeaTalk NG, Simrad Simnet, and Furuno CAN are rebranded implementations of NMEA 2000, though may use physical connectors different from the standardised DeviceNet Micro-C M12 5-pin screw connector, all of which are electrically compatible and can be inter-connected. The higher-level protocol format is based on SAE J1939, with specific messages for the marine environment. Electrically, NMEA 2000 is compatible with the Controller Area Network ("CAN Bus") used on road vehicles and fuel engines. N2K communication runs at 250 kilobits per second and allows any sensor to talk to any display units or other device compatible with NMEA 2000 protocols. NMEA 2000, abbreviated to NMEA2k or N2K is standardised as IEC 61162-3. Your monitor point can be extended to your smart phone, iPad or notebook. All sensors and navigation devices can be monitored from one central point, thereby improving safety of lives. NMEA 2000 is a plug-and-play communications standard used for connecting marine sensors, AIS, RADAR, VHF radios and display systems within ships and boats. While you focus on the enjoyment thereof, let our NMEA devices work for you. Improve your yachting or boating experience.
