Xenon/Granit User Guide 173
Discard Data
B8 Discards types of data. For example, you may want to discard Code 128 bar codes
that begin with the letter A. In step 4 (page 158), select 6A (for Code 128), and in step
5, select 9999 (for all lengths). Enter FE41B8 to compare and discard Code 128 bar
codes that begin with the letter A. Syntax = B8.
Note: The B8 command must be entered after all other commands.
The Data Format must be Required (see page 173) in order for the B8 command to
work.
If Data Format is On, but Not Required (page 174), bar code data that meets the B8
format is scanned and output as usual.
Because the data format needs to be On and Required (page 174) for the B8
command, you must input data formats for all bar codes you wish to discard as well
as all bar codes you wish to output.
Other data format settings impact the B8 command. If Data Format Non-Match Error
Tone is On (page 174), the scanner emits an error tone. If Data format Non-Match
Error Tone is Off, the code is disabled for reading and no tone is sounded.
Data Formatter
When Data Formatter is turned Off, the bar code data is output to the host as read,
including prefixes and suffixes.
You may wish to require the data to conform to a data format you have created and
saved. The following settings can be applied to your data format:
• Data Formatter On, Not Required, Keep Prefix/Suffix
Scanned data is modified according to your data format, and prefixes and
suffixes are transmitted.
• Data Formatter On, Not Required, Drop Prefix/Suffix
Scanned data is modified according to your data format. If a data format is
found for a particular symbol, those prefixes and suffixes are not transmitted. If
a data format is not found for that symbol, the prefixes and suffixes are
transmitted.
• Data Format Required, Keep Prefix/Suffix
Scanned data is modified according to your data format, and prefixes and
suffixes are transmitted. Any data that does not match your data format
requirements generates an error tone and the data in that bar code is not
transmitted. If you wish to process this type of bar code without generating an
error tone, see Data Format Non-Match Error Tone.
• Data Format Required, Drop Prefix/Suffix
Scanned data is modified according to your data format. If a data format is
found for a particular symbol, those prefixes and suffixes are not transmitted.
