MWV Wind Speed and Direction
Query
Use a MWV query command to request the wind speed and direction
data. To use MWV query the NMEA Wind formatter parameter in the
wind sensor settings must be set to W. See Wind Sensor on page 127.
The MWV command only queries only wind speed and direction
average values. For details on obtaining minimum and maximum data
for speed and direction, see XDR Transducer Measurement Query on
page 116.
