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 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 bar code’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 bar code to enter Programming Mode.
3. Scan the bar code to SELECT LENGTH 1 SETTING for your selected symbology.
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.
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.
5. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Prog Mode.
Set Length 2
This feature allows you to set one of the bar code lengths for the specified symbology. Length 2 is the maximum
label length if in
Variable Length Mode, or the second fixed length if in Fixed Length Mode. See the page for the
specific symbology for parameters.
The length that can be set varies depending on the symbology. A setting of 0 specifies to ignore this length (only
one fixed length).
Follow these instructions to set this feature:
1. Determine the desired character length (from 1 to 50 — or 0 to ignore this length). 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 bar code to enter Programming Mode.
3. Scan the bar code to SELECT LENGTH 2 SETTING for your selected symbology.
