knot if n=4

mph if n=5
Default : m/s (n=1)
RGUV n| Reads the wind speed measuring unit set
in the instrument
CGUTn &| Sets temperature measuring unit:

°C if n=1

°F if n=2
Default : °C (n=1)
RGUT n| Reads the temperature measuring unit set
in the instrument

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
Default : 1 s
