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 symbol-
ogy. Reference the page for your selected symbology to see specific vari-
ables.
1. Determine the desired character length (varies depending on symbol-
ogy). Pad the number with leading zeros to yield two digits. For exam-
ple: 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 sym-
bology.
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 begin-
ning.
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 spe-
cific 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).
