Decoding Safety is used to configure a decoder to be very aggressive to very conservative,
depending on a particular customer's needs.
- Level 1 results in a very aggressive decoder.
- Level 5 results in a very conservative decoder at the expense of not being able to read poorly
printed or damaged labels.
There are many factors that determine when to change the decoding safety. These factors
include spots, voids, non-uniform backgrounds, 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, decrease the decoding safety to be more aggressive. In case of rig-
orous reliability application requirements it is suggested to use higher decoding safety values
(conservative).
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.
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 PRO-
GRAMMING MODE barcode to enter Programming Mode.
3 Scan the barcode to SELECT LENGTH 1 SETTING for your selected symbology.
4 Scan the appropriate two digits from the keypad in
length setting which was determined in the steps above. You will hear a two-beep indication
after the last character.
If you make a mistake before the last character, scan the CANCEL barcode to
abort and not save the entry string. You can then start again at the beginning.
NOTE
5 Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Prog Mode.
