Description
aAb!
where:
b = new
address
b<CR><LF>
Note: if character b is not an acceptable address,
the instrument answers with a in the place of b.
Change of instrument
address.
?! a<CR><LF>
Request
for
instrument
address. If more than a
sensor is connected to the
bus, a conflict will occur.
aM! atttn<CR><LF>
where:
a = address of the instrument (1 character)
ttt = number of seconds needed by the instrument
to make measurements available (3 charac-
ters)
n = number of detected quantities (1 character)
Note: ttt is always equal to 000 because the meas-
uring process is continuous. Measurements can be
directly requested (command aD0!) without send-
ing this command before.
Request to perform the
measurement.
aD0!
aD1!

<C>
= compass angle in degrees
<WSa> = mean wind speed
<WDa> = mean wind direction in degrees
<WGS> = wind Gust intensity
<WGD>
= wind Gust direction in degrees
<TBT> = total amount of rainfall
<TBL> = partial amount of rainfall
<RR> = rainfall rate
Notes:
The positive values are always preceded by a +
sign to identify the beginning of the measurement
value.
Request for measured
values.
