Check Sum; Status Information - Thies CLIMA First Class Advanced X Instructions For Use Manual

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.

Description
= 1 if the difference between the wind velocity between
2 subsequent measured values in the second interval
exceeds 10m/s.
= 1 if the wind velocity remains for at least 3 hours at
0m/s without interruption.
= 1 if the measured wind velocity is outside the defined ta-
ble range.
= 1 after a reset conditioned by the watchdog.
= 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.
Bits 5 to 8 show the calibration table used for the calcula-
tion of the wind velocity.

=1, Vcc voltage outside admissible range.
=1, 3V voltage outside admissible range.
=1, measured values from the pressure sensor are faulty.
=1, measured values from the acceleration sensor are
faulty.
=1, internal EEPROM parameters invalid.
=1, internal EEPROM parameters contain the standard
values.
=1, last restart was done with new firmware.
Internal use.
