Module 12 – Multi-label
Description
The module permits the definition of multiple barcodes with a different number of digits and/
or code types in the reading gate and provides the necessary input data.
Parameters
Parameter length
2 byte
Input data
Input data length
1 byte
Output data
None
This module is used to set the maximum and minimum number of barcodes which are to be
decoded within a reading gate.
If parameter "minimum number of barcodes" = 0, it is not taken into account at the decoder
controller. If it is not equal to 0, this means that the barcode reader expects a number of
labels within the set range.
If the number of decoded barcodes is within the set limits, no additional "No Reads" are
output.
Notice!
When using this module, the ACK mode should be activated (see Module 10 – Activations,
"Mode" parameter). Otherwise there is a risk of losing decoding results if the control is not
fast enough.
