Multiple physical listeners can be connected to the Router's outputs. This allows organization of data exchange between multiple devices with different speeds. The Router has four physical NMEA 0183 ports (four inputs and four outputs) with configurable speed from 300 to 115200 baud.
With it, you get marine network data including vessel course, speed, position, wind speed and direction, water depth, AIS messages from vessels and aircraft and other navigation data in popular software applications. The YDWR-02 WiFi Router is a smart NMEA 0183 and SeaTalk multiplexer which also allows you to see data from marine devices on a PC, tablet or smartphone.
Manufacturers also offer Bluetooth communication as an option. Various NMEA product manufacturers have integrated WiFi into their product, transmitting NMEA messages via UDP and/or TCP messages. Through the use of intermediate expanders, a talker can have a unidirectional conversation with a nearly unlimited number of listeners, and using multiplexers, multiple sensors can talk to a single computer port.Īt the application layer, the standard also defines the contents of each message type, so that all listeners can parse messages accurately.
The NMEA 0183 standard uses a simple ASCII, serial communications protocol that defines how data is transmitted in a message from one "talker" to multiple "listeners" at a time.
Although the standard calls for isolated inputs and outputs, there are various series of hardware that do not adhere to this requirement. In leisure marine applications it is slowly being phased out in favour of the newer NMEA 2000 standard, though NMEA0183 currently remains the norm in commercial shipping. The NMEA0183 standard is controlled by the National Marine Electronics Association (NMEA). NMEA 0183 Version 4 includes TAG Blocks, supporting network (LAN / WAN) operations. NMEA 0183 is a combined electrical and data specification for communication between marine electronics such as plotters, echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of marine instruments. The interconnectivity among instruments in the network allows, for example, the GPS receiver to correct the course that the autopilot is steering. 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.
