The NMEA 0183 Protocol


NMEA 0183 is a combined electrical and data specification for communication between marine electronics such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments.

What is the difference between NMEA 0183 and NMEA 2000?

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.

What are the NMEA sentences used for?

The idea of NMEA is to send a line of data called a sentence that is totally self contained and independent from other sentences. There are standard sentences for each device category and there is also the ability to define proprietary sentences for use by the individual company.

How to connect your wind meter to NMEA 0183?

NMEA 0183 Sentence 

This is the NMEA 0183 sentence you can use for communication with your wind meter :

As an example , we could set  $IIMWV,316,R,06.8,N,A*19 where  1=316, 2=R, 3=06.8 , 4=N and 5=A.
