Parameters
5.7.7.1.2 Transmit start/stop
If the Transmit start/stop parameter is activated, the start and stop characters are trans-
mitted together with the code contents.
As a result, the characters are available for evaluation of the reading results.
5.7.7.1.3 Full ASCII
The Full ASCII parameter must be activated if the code contains both digits and other cha-
racters.
5.7.7.1.4 Check digit test
This Check digit test parameter is used to define the calculation method for the plausibility
check on the code contents. A check digit is calculated from the code contents and compa-
red with the check digit in the code. The selected method must match the method used du-
ring creation of the code. If the calculated check digit matches the check digit in the code,
the reading is regarded as a G
OOD READ).
Check digits prevent misinterpretations and increase reading reliability.
5.7.7.1.5 C32 conversion
If the C32 conversion parameter is activated, decoding is activated for the code type.
As only activated code types are processed, you can increase the processing speed by
specifically activating/deactivating the required code types.
