SYMBOLOGIES
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
1D Symbologies, starting on page 103
to view the selectable range (num-
ber 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
Appendix D
, that represent the
length setting which was determined in the steps above. You will hear a two-beep
indication after the last character.
5. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Programming Mode.
This completes the procedure. See the following table for examples of how to set this
feature.
Table 19 Length 1 Setting Examples
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 beginning.
