Parameters for SDI-12 mode:
Command Reply Description
CU3Ac &| Sets the SDI-12 address to c value
The address is an alphanumeric character
ranging within 0…9, a…z, A…Z. Default : 0
RU3A & c| Reads the SDI-12 address set in the instru-
ment
General parameters:
Command Reply Description
CGHn &| Enables/disables heating:

Disables if n=0

Enables if n=1
Default : Enabled (n=1)
RGH n| Reads heating enabling state set in the in-
strument
CWCnnnn &| Sets wind speed threshold to nnnn value (in
hundredths of m/s)
Value should range within 0 and 100 hun-
dredths of m/s (= 0…1 m/s)
Default : 20 (= 0.2 m/s)
(see Note 3)
RWC & nnnn| Reads the wind speed threshold value set in
the instrument (in hundredths of m/s)
CWaLnnn &| Sets time interval for the calculation of aver-
age speed and average direction to nnn value
Value should range within 1 and 600 s.
If the value is greater than 10 s, it must be
an integer multiple of 10.
note:the value can be greater than or equal to 10
s starting from firmware version 2.20
Default : 1 s
RWaL & nnn| Reads the time interval for the calculation
of average speed and average direction set
in the instrument
CWaMn &| Sets the method for the calculation of
average speed and average direction:

If n=0: scalar mean. The average inten-
sity is calculated as average of intensities
without consideration of
direction. The
average direction is calculated as average
of directions, and expressed according to
the extended characteristic
(see Note 4)
.

If n=1: vector mean. The average of the
coordinates along each measurement axis
is calculated. The average intensity and
the average direction are those deter-
mined by the two average coordinates.
Default : vector mean (n=1)
