Control Commands
The easiest way to trigger and parameterize the sensors is by using a PC with RS232 communication port
and a terminal program, see Chap.
11.
The communications protocol is available in ASCII format.
Before an operating session begins, desired parameter settings can be made in a smart selection procedure
until the measuring module is optimally adapted to the particular measuring site conditions and the measu-
ring job. All valid settings will be preserved on turning the sensor off. They can only be replaced with new
value entries or changed back to their standard values by running an initialization routine.
Command entries are not case-sensitive. This means that small and capital lettering can be used for com-
mands. Any command which is to be sent to the sensor must be terminated by a hexadecimal 0Dh (carriage
return) character.
Where decimal digits are to be entered, they must be separated by period (2Eh).
For command parameter entries, one must distinguish between parameter settings and parameter queries.
Querying is achieved with a command in simple format, for example analog output: QA[Enter].
For parameter setting, a new value must be added after the command with no delimitation sign in between,
for example: QA50 250[Enter].
With multi-value parameters, space (0x20) is used between each two values.

Identification
In response to an ID command, the sensor outputs its manufacturing data in this order: product type, firm-
ware version, firmware data, firmware time, fabrication number, date of manufacture and time of manufacture.
