Setting Global
Prefix(es)
One or two prefix characters may be added to the standard label for-
mat when desired. For the addition of more than two prefix characters,
contact your distributor or technical support representative for Full
Label Edit (FLE) options.
Identify your specific system requirements before adding or modifying
these settings, then follow these steps:
1. Look at the ASCII chart shown on the inside back cover of this
manual, and identify the ASCII character(s) and the corre-
sponding Hex Code(s) for the ASCII characters you will use as
prefixes.
For example, if you are going to send two prefix characters as ‘STX’
(start transmit) and ‘SP’ (Space), the ASCII chart shows that ‘STX’
equals 02 hex and ‘SP’ equals 20 hex.
2. Scan the SET bar code on page 50.
3. Scan the SET PREFIX bar code.
4. Turn to Appendix C: Keypad on page 147, and scan the four dig-
its corresponding to the hex values determined in step one
above. (For the example, scan 0, 2, 2, 0). Return to this page and
go to step five.
5. Scan the END bar code.
You have added a two character prefix to all bar code data, regardless
of label symbology, that will be added to the label data before it is sent
to the host.
NOTE
Successful programming of a prefix requires 4
digits.
NOTE
If you make a mistake or lose your place while
setting this option, scan the END bar code to
exit Programming Mode. The scanner will
sound a two-beep error tone to indicate that
programming was incomplete, and the setting
will remain as it was before entering Program-
ming Mode.
