Symbologies
Decoding Level
Decoding Levels are used to configure a barcode symbology decoder to be very aggressive to
very conservative depending on a particular customer’s needs.
• Level 1 results in a very conservative decoder at the expense of not being able to read
poorly printed or damaged labels.
• Level 5 results in a very aggressive decoder. This aggressive behavior allows decoding of
poorly printed and damaged labels at the expense of increasing the likelihood of decoding
errors.
• Level 3, which is the default setting, allows the majority of product labels to be decoded.
There are many factors that determine when to change the decoding level for a particular
symbology. These factors include spots, voids, non-uniform bar/space widths, damaged labels,
etc. that may be experienced in some barcode labels. If there are many hard to read or damaged
labels that cannot be decoded using a conservative setting, increase the decoding level to be
more aggressive. If the majority of labels are very good quality labels, or there is a need to
decrease the possibility of a decoder error, lower the decoding level to a more conservative level.
Set Length
Length Control allows you to select either variable length decoding or fixed length decoding for
the specified symbology.
Variable Length. For variable length decoding, a minimum and maximum length may be set.
Fixed Length. For fixed length decoding, two different lengths may be set.
