Figure 5.49 Case Rule Definitions
5.8.3.1 Case Rules
The case rules are defined as follows:
•
No rule —ignored.
• Match at index —matches the match string at a specified index.
• Match and replace at index —matches the match string at a specified index and
replaces/changes it.
• Replace at index —replaces/changes unspecified data in a given range.
• Add barcode prefix/suffix —adds a global prefix or suffix.
• Verify barcode size —verifies the bar code size. This rule should generally be assigned
first, before creating subsequent rules.
• Search and replace —replaces all instances of the match string. (Note that this rule
cannot fail.)
Translation information about the status of each case/rule is displayed in the scan log file, if
enabled (see “Scan Log File” on page 89). This is useful if a case fails, and you are trying to
determine why a rule is failing.
5.8.4 Ports Tab
While you cannot configure external decoded scanners, you can configure communications
with a serial decoded scanner using the options in this tab.
Note: Keep in mind that the effects of previously applied rules must be taken into
account when creating subsequent rules. For example, if the bar code size is
important, it should be checked before any rules that might change the size
are applied.
