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

1 2 ... 97 98 99 100 101 102 103 104 105 106 107 ... 170 171
