Data read by the scanner will be processed in the following sequence (RS-

2) The Code ID and the Length Code are inserted at the beginning of the
data as shown below.
[Code ID] [Length Code] [Data]
3) The resulting data of step 1 will be processed by the editing formats. For

5.1 Character Substitution
There are three character substitution settings on the scanner. These
settings are configured on a character base, i.e, a specific character is to
be substituted by an another character. The character substitution is
performed on every occurrence of the characters specified in these
settings. Be aware, the substitution is performed only on the barcode itself
(exclude Prefix Code, Postfix Code, Code ID, Length Code or any
Additional Field) and is performed before editing mode processing.
If only the character to be replaced is specified, every occurrence of that
character in the barcode will be taken away.
5.2 Prefix / Postfix Code
Up to four characters of prefix / postfix code can be configured for the
scanner.
