You can change the following settings:

  • Parameters included in the wind data message
  • Update interval
  • Averaging time
  • Wind speed max/min calculation mode
  • Speed unit
  • Direction offset
  • NMEA wind formatter

Change the settings with the following command.

Command format in ASCII and NMEA 0183:

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

Command format in SDI-12:

aXWU, R=x,I=x,A=x,G=x,U=x,D=x,N=x,F=x!
R, I, A, G, U, D, N, F Wind sensor setting fields.
x Value for the setting
<cr><lf> Command terminator in ASCII and NMEA 0183
! Command terminator in SDI-12
If averaging time [A] is greater than update interval [I], it is a multiple of the update interval and at maximum 12 times greater. Example: If I = 5 s, Amax = 60 s.

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

You need a 20-second averaging time for wind speed and direction both in wind data and composite data message in every 60 seconds. Wind speed is in knots and wind direction offset +10°.

Changing the measurement interval to 60 seconds:

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

0WU,I=60<cr><lf>
Several parameters can be changed with the same command as long as the command length does not exceed 32 characters.

Changing the averaging time to 20 seconds, the wind speed unit to knots, and direction offset to +10°:

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

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

Changing the wind parameter selection:

0WU,R=0100100001001000<cr><lf>

0WU,R=01001000&00100100<cr><lf>
Character '&' is not allowed in the command.

The wind message response after the change above:

0R1<cr><lf>

0R1,Dm=268D,Sm=1.8N<cr><lf>

Example (SDI-12, device address 0):

Changing the measurement interval to 10 seconds:

0XWU,I=10!0<cr><lf>

In SDI-12 mode a separate enquiry (0XWU!) must be given to check the data.
