Data Format Setup
The Data Format tab allows the user to specify the format of the data
that is returned by the Scanner.
Format
The Format drop-down box allows you to select if a prefix and/or
suffix character are added to the bar code data. The prefix character is
added before the bar code data. The Suffix 1 character is appended to
the end bar code data and the Suffix 2 character is appended after the
Suffix 1 character. If Suffix 1 is not selected, Suffix 2 is appended to
the end of the bar code.
Tap on the down arrow on the right side of the Format box to access
a drop-down menu of the available data format. Tap on the format
you want to use. The eight Format options are:
