Command format in ASCII and NMEA 0183:

aWU,R=x,I=x,A=x,U=x,D=x,N=x,F=x<cr><lf>

Command format in SDI-12:

aXWU, R=x,I=x,A=x,U=x,D=x,N=x,F=x!

Examples (ASCII and NMEA 0183, device address 0):

You need 20 seconds averaging time for wind speed and direction data
to be available both in wind data message and composite data message
in every 60 seconds. Wind speed in knots and wind direction correction
+10°.

Changing the measurement interval to 60 seconds:

0WU,I=60<cr><lf>

0WU,I=60<cr><lf>

Changing the averaging time to 20 seconds, the wind speed units to
knots, and making the direction correction:

0WU,A=20,U=N,D=10<cr><lf>

0WU,A=20,U=N,D=10<cr><lf>

NOTE

If averaging time [A] is greater than update interval [I], it shall be a
whole multiple of the update interval and at maximum 12 times
greater. Example: If I = 5 s, A

max

= 60 s.

NOTE

Several parameters can be changed with the same command as long as
the command length does not exceed 32 characters, see below.
