Attention!
Due to its internal design (hardware-ASIC-decoding), only one double-width code may be
enabled for the BCL40.
Double-width codes are the codes Code 2/5 Interleaved, Code 39 and Codabar.
This means that only one of these three code types may be enabled!

This value may be changed only in special cases!
Quiet zone size
Quiet zone: the area to the left and right of the bar code
Module: width of the narrowest line in the bar code
According to the code specifications, each bar code must have a quiet
zone which is 10x as wide as the module of the bar code.
Ex: for a code having a module of 0.5mm, 5mm blank space must be
present at both the left and right of the code.
By default, the scanner checks the a quiet zone which is 7 times
greater than the module. This means that 7x or greater is o.k.
Scans between
info
Number of scans which return no decodable data for a given label
which must be performed before further data are classified as belong-
ing to a different label. In this way it is possible to differentiate between
sequential labels with identical data. This setting does not need to be
changed in normal use.
Reading security
(equal scans)
Specifies how often a code must be decoded before the result is valid
and output. This value can be increased for inspection and test
purposes.
