Message Format Parameters
This chapter defines parameters that control the
format of transmitted bar code messages including:
•
Prefix and Suffix
•
Scanner Identifier
•
Code Identifier
•
Preamble and Postamble
In addition to these parameters, you can program an
intercharacter delay to prevent data overruns with
your host computer/terminal or wedge.
A message transmitted from the scanner upon a
successful decode has the following format:
Prefix Scanner Identifier Code Identifier Data Postamble Suffix Preamble
Some of these message parameters may not be
required or may vary from one host system to
another. You select parameters based on the
requirements of your application and the host system.
To select message parameters, you scan the
appropriate bar code labels in each section.
Note: Throughout this chapter default settings for
parameters are flagged by an asterisk (*).
