10. Fixing the Number of Digits
To avoid truncation errors, the scanner can be programmed to only decode bar codes of one specific length,
i.e., containing a specific number of digits. It is also possible to program the scanner to only decode bar codes
of either of two specific lengths.
To fix one (1) length (or number of digits) of bar code:
1.
Scan “START” to enter the programming mode.
2.
Scan “Enable fixation” bar code.
3.
Scan a sample bar code of the desired length.
4.
Repeat Step #3, re-scanning the sample bar
code.
5.
Scan “STOP” to exit the programming mode.
To fix two (2) different lengths of bar codes:
1.
Scan “START” to enter the programming mode.
2.
Scan “Enable fixation” bar code.
3.
Scan a sample bar code of the desired length #1.
4.
Scan a sample bar code of the desired length #2.
5.
Scan “STOP” to exit the programming mode.
Note
Fixation can also be programmed using computer commands through your
RS-232C by typing <ESC>7V<CR> followed by <+>2 digit length 1<CR>. 7W
would be appropriate for length 2. Type <+>00<CR> to define either length as
no fixed number. “Fixing the Number of digits” can only be applied to Code 39,
Codabar (NW-7), 2 or 5 and MSI/Plessey. WPC, Code 39, IATA and Code 128
are not affected.
