The structure of the wind sensor response message:
where
$ = Start of the message
WI = Device type (WI = weather instrument)
XDR = Transducer measurement response identifier
A = Transducer id 0 type (wind direction), see the
following Transducer table
302 = Transducer id 0 data (min wind direction)
D = Transducer id 0 units (degrees, min wind direction)
0 = Transducer id for min wind direction
A = Transducer id 1 type (wind direction)
320 = Transducer id 1 data (average wind direction)
D = Transducer id 1 units (degrees, average wind
direction)
1 = Transducer id for average wind direction
A = Transducer id 2 type (wind direction)
330 = Transducer id 2 data (max wind direction)
D = Transducer id 2 units (degrees, max wind direction)
2 = Transducer id for max wind direction
S = Transducer id 0 type (wind speed)
0.1 = Transducer id 0 data (min wind speed)
M = Transducer id 0 units (m/s, min wind speed)
0 = Transducer id for min wind speed
S = Transducer id 1 type (wind speed)
0.2 = Transducer id 1 data (average wind speed)
M = Transducer id 1 units (m/s, average wind speed)
1 = Transducer id for average wind speed
S = Transducer id 2 type (wind speed)
0.2 = Transducer id 2 data (max wind speed)
M = Transducer id 2 units (m/s, max wind speed)
2 = Transducer id for max wind speed
* Checksum delimiter
57 = Two-character checksum for the response
<cr><lf> = Response terminator
