received. The expected number of measurements is the one that WS
received by the data recorder in response to an M! or V! command.
Multiple data requests are not needed with WS425, since all return values
fit easily into one response string.
The command is the following:
aD0!
where
a = The sensor address.
D0 = The send data command.
! = Terminates the command.
When the previous command WS aM! is given, the response is the
following:
a<WS><WD><x><y><s><CR><LF>
where
a = The sensor address.
<WS> = Polar wind speed in selected units, format:
+(ss)s.s
<WD> = Polar wind direction in degrees, format +(dd)d
<x> = x component of wind speed in selected units,
format:
±(ss)s.s
<y> = y component of wind speed in selected units,
format:
±(ss)s.s
<s> = Static speed of sound in mph, format:
±(ss)s.s
<CR><LF> = Terminates the response.
The above are measurement data fields.
If data is missing due to a measurement problem (for example, blocked
paths between transducers), the measurement data is replaced with 999
as follows:
>7D0!
7+999.9+9999+999.9+999.9+999.9
