±3.3333±4.4444],PP.PPC,<ETX>CC<CR><LF>
Where:
<STX> - Start of string character (ASCII value 2)
<ID> - Anemometer Identification (A-Z)
DDD - Direction in degrees
MMM.MM - Wind Magnitude
±WWW.WW - ‘W’ axis velocity 0.01ms
-1
units
U - Units (M=m/s, N=knots, P=mph, K=kph)
±CCC.CC - Speed of Sound in 0.01ms
-1
units
±TTT.TT - Sonic Temperature in Degrees C.
SS - Status data (Codes 00 to 0B)
±1.1111 - Analogue input 1 in volts
±2.2222 - Analogue input 2 in volts
±3.3333 - Analogue input 3 in volts
±4.4444 - Analogue input 4 in volts
±PP.PPC - PRT temperature in degrees C, e.g. +23.13deg C output as +23.13C in the string.
<ETX> - End of string character (ASCII value 3)
CC - Checksum of all Characters between <STX> and <ETX> (HEX byte)
<CR><LF> - Carriage Return and Line Feed

7.5. Mode 7 –Binary, Polar, Short
<B1><B1>STATUS,DIR,MAG,W,SOS,CHECKSUM
<B1> -
<B1> -
STATUS - Status data (Codes 00 to 10)
DIR Wind Direction
MAG Wind Speed
W W axis velocity
SOS Speed of Sound in 0.01ms
CHECKSUM
Notes:-
Data is 2 byte signed two’s complement (except unsigned for SOS; 1 byte for checksum).
Velocities are normal resolution (0.01m/s).
Outputs that are disabled are padded with zero to give fixed size records.
