Variable Description Byte
0xB4 0xB4 Start message identifier (HEX B4 = decimal 180) 1+2
Sta Status data (Information only on low byte (Codes 00 to 0B), 3+4
high byte always zero).
Wc1 U axis wind velocity (16 bit signed integer). 5+6
Wc2 V axis wind velocity (16 bit signed integer) 7+8
Wc3 W axis wind velocity (16 bit signed integer) 9+10
SoS Speed of Sound in 0.01ms (16 bit signed integer) 11+12
A1 Analogue input 1 (16 bit signed integer). 13+14
A2 Analogue input 2 (16 bit signed integer). 15+16
A3 Analogue input 3 (16 bit signed integer). 17+18
A4 Analogue input 4 (16 bit signed integer). 19+20
TPrt Temperature from PRT (16 bit signed integer). 21+22
Checksum Checksum (exclusive OR of bytes between 23
start of message identifier and checksum byte).
SoS is always reported as Speed of Sound independent of A command setting.
TPrt is always reported independent from the V command setting.
A1 to A4 are always reported independent from the I command setting.
