Analog outputs:
Command Reply Description
RAT & n| Reads the analog output type:

4…20/0…20 mA if n=0

0…1 V if n=1

0…5 V if n=2

0…10 V if n=3
CAFxnn &| Sets offset and direction of the analog output
x (x=1 or 2) to:

Standard if nn=00
[ ex. 4…20 mA , 0...1 V , 0...5 V , 0...10 V ]
 Without offset if nn=01
[ ex. 0…20 mA ]

With offset if nn=02
[ ex. 0.2...1 V , 1...5 V , 2...10 V ]

Inverted if nn=04
[ ex. 20…4 mA , 1...0 V , 5...0 V , 10...0 V ]

Inverted without offset if nn=05
[ ex. 20…0 mA ]

Inverted with offset if nn=06
[ ex. 1...0.2 V , 5...1 V , 10...2 V ]
Default : Standard (nn=00)
RAFx & nn| Reads offset and direction setting of the ana-
log output x (x=1 or 2)
CAMn &| Association of the analog outputs:
 If n= 0:
Output 1 = Mean wind speed
Output 2 = Mean wind direction (with ex-
tended characteristic if the
average is scalar)

If n= 1 (
see Note 7
):
Output 1 = Instant wind speed component
along V-axis
Output 2 = Instant wind speed component
along U-axis

If n= 2 ( Tunnel mode,
see Note 8
):
Output 1 = Instant wind speed component
along the direction indicated by
the reference (arrow or notch)
on the instrument housing
Output 2 = Instant wind direction referred
to the direction indicated by
the reference (arrow or notch)
on the instrument housing
Default : n=0
