Setting Fields
The parameter order is shown in the following table:
[R] = Parameter selection: This field consists of 16 bits
defining the precipitation parameters included in the
data messages. The bit value 0 disables and the bit
value 1 enables the parameter.
The bits 1-8 determine the
parameters in the data
message obtained with the
following commands:
-ASCII: aR1 and ar1
-NMEA 0183: $--WIQ,XDR*hh
-SDI-12: aM1, aMC1, aC1, and
aCC1
-SDI-12 continuous: aR1 and
aRC1 1st bit (most left) Dn Direction minimum
2nd bit Dm Direction average
3rd bit Dx Direction maximum
4th bit Sn Speed minimum
5th bit Sm Speed average
6th bit Sx Speed maximum
7th bit spare
8th bit spare
& delimiter
The bits 9-16 determine the
wind parameters in the
composite data message
obtained with the following
commands:
-ASCII: aR0, ar0
-NMEA 0183: aR0, ar0
-SDI-12: aM, aMC, aC, and aCC
-SDI-12 continuous: aR and
aRC 9th bit Dn Wind direction minimum
10th bit Dm Wind direction average
11th bit Dx Wind direction maximum
12th bit Sn Speed minimum
13th bit Sm Speed average
14th bit Sx Speed maximum
15th bit spare
16th bit (most right) spare
[I] = Update interval: 1 ... 3600 seconds
[A] = Averaging time: 1 ... 3600 seconds
Defines the period over which the wind speed and
direction averaging is calculated. See also Appendix
D for averaging method.
[U] = Speed unit: M = m/s, K = km/h, S = mph, N = knots
[D] = Direction correction: -180 ... 180°, see Wind
Direction Correction on page 34 .
