Data Editing
Data Editing Overview
When a bar code is scanned, additional information can be sent to the
host computer along with the bar code data. This combination of bar
code data and supplementary user-defined data is called a “message
string.” The features in this chapter can be used to build specific
user-defined data into a message string.
There are several types of selectable data characters that can be sent
before, after, and even between scanned data. You can specify if they
should be sent with all symbologies, or only with specific symbologies.
Figure 5-1 shows the available elements you can add to a message string:
