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 shall be in knots and wind direction offset +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 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>
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 content.
NOTE Several parameters can be changed with the same command as long as
the command length does not exceed 32 characters, see below.
NOTE Character '&' is not allowed in the command.
