Notice!
In general, the remaining parameters must not be changed. In the worst case, this could
corrupt the reading result!
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 or narrowest gap in the bar code
According to the code specifications, each bar code must have a quiet zone which
is 10 times 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 a quiet zone which is 7 times greater than the module.
This means that 7 times or greater is o.k.
Reading security
(equal scans)
Specifies how often a code must be decoded before the result is valid and output.
Increasing this value increases the reading reliability, though does so at the expense
of the decoding time (more scans with the same content are necessary).
No time correlation
If this parameter is set, a gap between two identical labels is ignored and they are
treated as a single label.
No position correlation
If this parameter is set, then the position of a bar code label in the reading beam is
not taken into account. Identical labels are treated as a single label
