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.
Set Length 1
This feature specifies one of the barcode lengths for Length Control. Length 1
is the minimum label length if in Variable Length Mode, or the first fixed length
if in Fixed Length Mode. Length includes the barcode’s data characters only.
The number of characters that can be set varies, depending on the symbology.
Reference the page for your selected symbology to see specific variables.
1. Determine the desired character length (varies depending on symbology).
Pad the number with leading zeroes to yield two digits. For example: 0 =
00, 5 = 05, 20 = 20, etc.
2. Go to the Set Length page for your selected symbology and scan the
ENTER/EXIT PROGRAMMING MODE barcode to enter Programming Mode.
3. Scan the barcode to SELECT LENGTH 1 SETTING for your selected symbol-
ogy.
4. Scan the appropriate two digits from the keypad in Appendix D, Keypad ,
that represent the length setting which was determined in the steps above.
You will hear a two-beep indication after the last character.
