Changing the Settings (aWU)
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, and
- NMEA wind formatter.
Change the settings with the following command. For details on the
value or letters for the setting fields, see the examples and Setting Fields
on page 129.
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!
where
R, I, A, G, U,
D, N, F
= Wind sensor setting fields. See Setting Fields on
page 129.
x = Value for the setting
<cr><lf> = Command terminator in ASCII and NMEA 0183
! = Command terminator in SDI-12
NOTE
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, A
max
= 60 s.
