Code 39 — cont.
Code 39 Set Length 2
This feature specifies one of the bar code lengths for Code 39 Length Control. Length 2
is the maximum label length if in Variable Length Mode, or the second fixed length if
in
Fixed Length Mode. Length includes the bar code’s check, data, and full-ASCII shift
characters. The length does not include start/stop characters.
The length can be set from 1 to 50 characters. A setting of 0 spe
cifies 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. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Programming
Mo
de.
3. Scan the bar code: SELECT CODE 39 LENGTH 2 SETTING.
4. Scan the appropriate two digits from the keypad in Appendix E, Keypad, that represent
the length setting which was determined in the s
teps above. You will hear a two-beep indi-
cation after the last character.
NOTE
If you make a mistake, before the la
st 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 Programming
Mode.
This completes the procedure. See Table 22 for some examples of how to set this feature.
