Data Format Options

Prefix / Suffix

You can add a prefix/suffix to bar code data. To enter a prefix/suffix,
you must scan a four digit number (four bar codes) that represents
the ASCII equivalent value for each character (See ASCII Characters
in Appendix C). When you enter the last digit of a prefix or suffix,
the scanner lets you know that you have entered a valid value by
providing a high-low-high beep.
The default prefix/suffix is the ENTER key (ASCII equivalent
1073).
For example, to add the prefix < (ASCII equivalent 1060) to bar
code data, scan these labels:
–
Prefix
–
1 (under Prefix/Suffix Values)
–
0 (under Prefix/Suffix Values)
–
6 (under Prefix/Suffix Values)
–
0 (under Prefix/Suffix Values)
For example, to add the suffix > (ASCII equivalent 1062) to bar code
data, scan these labels:
–
Suffix
–
1 (under Prefix/Suffix Values)
–
0 (under Prefix/Suffix Values)
–
6 (under Prefix/Suffix Values)
–
2 (under Prefix/Suffix Values)

Transmit No Read Message

When enabled, this option transmits "NR" when a symbol does not
decode. Enabled prefixes and suffixes are appended around this
message. The default is disabled.
