Check for non-numeric character
ED Check to make sure there is a non-numeric ASCII character at the current cursor
position. The format is aborted if the character is numeric.
ED Example: Only output the data if the barcode begins with a letter
If you want only data from barcodes that begin with a letter, you can use ED to
check for the letter.
Command string: EDF10D
ED is the “Check for a non-numeric character” command
F1 is the “Send all characters” command
0D is the hex value for a CR
If this barcode 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 barcode is read:
the data is output as:
AB1234
<CR>
Insert a delay
EF 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
Discard Data
B8 Discards types of data. For example, you may want to discard Code 128 barcodes
that begin with the letter A. In step 4 (page 60), select 6A (for Code 128), and in
step 5, select 9999 (for all lengths). Enter FE41B8 to compare and discard Code
128 barcodes 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 78) in order for the B8 command to
work.
