The decoder’s configuration may be changed by either scanning a series of
configuration bar code symbols or sending an escape sequence to the
decoder. Programming via escape sequences is covered in Chapter 5.
Default parameters are indicated by an asterisk (*). Appendix A lists the
decoder’s default settings.
To best use the configuration bar code symbols, it is important to understand
that there are three configuration types:
Exit
Command
A single scan that
completes a
configuration.
variable
Variable Command
Exit
Characters
End Of Characters
Message
Exit
Two scans, the first scan
specifying a variable to be
changed, and the second
scan specifying the new
variable value.
Type 2
Type 3
Type 1

Multiple scans: The first scan specifies
a type of message to be created, the
following scans specify the contents of
the message. When finished, the
operation is completed by scanning the
End Of Characters symbol.
