Decoding Levels
Decoding Levels are used to configure a bar code symbology decoder to be very aggressive to
very conservative depending on a particular customer’s needs.
•
Choosing Level 1 results in a very conservative decoder at the expense of not being able
to read poorly printed or damaged labels.
•
Choosing 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 likeli-
hood of decoding errors.
•
Choosing 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 bar code 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 bar code lengths for a given symbology. Length 1 is the
minimum label length if in Variable Length Mode, or the first fixed length if in Fixed Length
Mode.
Reference the
section to view the selectable range (number of characters) for the
symbology being set.
Follow these instructions to set this feature:
1.
Determine the desired character length. Pad the number with leading zeroes to yield two
digits. For example: 0 = 00, 5 = 05, 20 = 20, etc.
2.
Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Programming Mode.
3.
Scan the “Select Length 1 Setting” for the symbology being set.
4.
Scan the appropriate two digits from the keypad in
, that represent the
length setting which was determined in the steps above. You will hear a two-beep indi-
cation after the last character
NOTE
If you make a mistake before the last character, scan the CANCEL bar code to
abort and not save the entry string. You can then start again at the begin-
ning.
