Configuring the Scanner 4–9

Publication 2755-6.4

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.
