11.1.2 Check Sum:
The check sum is the XOR link of all characters between <XTX> and the byte <*>.
The asterisk is the separation character of the check sum and is not contained in the check
sum.
11.1.3 Status Information:
Within the wind transmitter, the status word (32bit) is available which provides information
about the condition of the transmitter. The measured values are submitted to a plausibility
check and shown in the status word.
Bit number Function Description
Bit 0 Wind velocity jump = 1 if the difference between the wind velocity between
2 subsequent measured values in the second interval
exceeds 10m/s.
Bit 1 Calm = 1 if the wind velocity remains for at least 3 hours at
0m/s without interruption.
Bit 2 Measured value correc-
tion = 1 if the measured wind velocity is outside the defined ta-
ble range.
Bit 3 Watchdog Reset = 1 after a reset conditioned by the watchdog.
Bit 4 Filling level averaging
buffer < 100% = 1, averaging buffer has not yet filled completely.
After a restart of the wind transmitter, this bit remains
set until the averaging buffer has been filled completely.
Bit 5…8 Calibration table Bits 5 to 8 show the calibration table used for the calcula-
tion of the wind velocity.
0000 : Standard curve
0001 : Calibration table 1
0010 : Calibration table 2
0011 : Calibration table 3
0100 : Calibration table 4
0101 : Calibration table 5
0110 : Calibration table 6
0111 : Calibration table 7
1000 : Calibration table 8
1001 : Calibration table 9
1010 : Calibration table 10
Bit 9 Vcc voltage =1, Vcc voltage outside admissible range.
Bit 10 3V voltage =1, 3V voltage outside admissible range.
Bit 11 Pressure sensor =1, measured values from the pressure sensor are faulty.
Bit 12 Acceleration sensor =1, measured values from the acceleration sensor are
faulty.
Bit 13 EEPROM parameter =1, internal EEPROM parameters invalid.
Bit 14 EEPROM parameter =1, internal EEPROM parameters contain the standard
values.
Bit 15 New FW =1, last restart was done with new firmware.
Bit 16 - Internal use.
