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 6-2), 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 6-16) in order for the
B8 command to work. If Data Format is On, but Not Required (page
6-17), bar code data that meets the B8 format is scanned and output
as usual.
Other data format settings impact the B8 command. If Data Format
Non-Match Error Tone is On (page 6-18), 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. Any data that does not match your data format requirements
generates an error tone. If you wish to process this type of bar code without
generating an error tone, see Data Format Non-Match Error Tone.
