In the measurement string sent by the instrument (constantly in proprietary RS232 mode, on
request in proprietary RS485 mode), measurements can be set in arbitrary order: one should
simply indicate the desired order in the sequence of characters "ccccccccccc" sent by the
command C1UD. The sequence of characters "ccccccccccc" can have a variable length up to a
maximum of 11 characters.
Example: if the sequence of characters is set to 78012, wind speed, wind direction, barometric
pressure, temperature and relative humidity measurements will appear from left to right in the
data string sent by the instrument.
If information on error conditions is requested (E character), three numbers with the following
meaning will appear in the data string sent by the instrument:
1. First number = error code identifying the transducers and the type of error.
The number is composed by two digits. The first digit indicates the path (that is the
transducers pair) that presents the error, according to the numeration indicated in
the figure:
Digit 7 indicates an error in the compass. Digit 0 indicates that no errors are present
in the ultrasonic transducers or in the compass.
The second digit of the error code indicates the type of error: 0 = no errors;
1 = transducer broken, electric interruption, path obstruction; Other = codes re-
served to technical service.
2. Second number = state of activation of the ultrasonic transducers heating.
0 = heating turned off, 1 = heating turned on
3. Third number = number of invalid measurements.
Example: if 21 0 2 appears in correspondence to the error condition in the data string sent by
the instrument, it means that an error occurred (broken transducer or path obstruction) in the
path number 2, that the heating is turned off and that two measurements have been rejected
due to the error occurrence.
