ED Example: Only output the data if the bar code begins with a letter
If you want only data from bar codes that begin with a letter, you can use ED to
check for the letter.
Command string: EDF10D
If this bar code is read, the next data format, if there is one, will be
used on this data. If there is no other format, the format fails and the raw data is
output as 1234AB.
If this bar code is read: the data is output as:
AB1234
<CR>
EF—Insert a delay
Inserts a delay of up to 49,995 milliseconds (in multiples of 5), starting from the
current cursor position. Syntax = EFnnnn where nnnn stands for the delay in 5ms
increments, up to 9999. This command can only be used with keyboard emula-
tion.a
B8—Discard Data
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 66), 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 81) in order for the B8 command to
work.
If Data Format is On, but Not Required (page 81), 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 82) 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 82), the scan engine emits an error tone. If Data format Non-Match
Error Tone is Off, the code is disabled for reading and no tone is sounded.
ED “Check for a non-numeric character” command
F1 “Send all characters” command
0D Hex value for a CR
