When you choose a rule, an associated screen is displayed in which you can define the rule.
4.20.3.1 Case Rules
The case rules are defined as follows:
• No rule — ignored.
• Search and replace — replaces all instances of the match string. (Note that this rule cannot fail.)
• 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 barcode size. This rule should generally be assigned first, before cre-
ating subsequent rules.
Translation information about the status of each case/rule is displayed in the scan log file (see “Scan Log
File” on page 88) when enabled. This is useful if a case fails, and you are trying to determine why a rule
is failing.
4.20.4 Ports
Figure 4.5 Console and Port Replicator Port Settings
While you cannot configure the scanner, you can configure communications with a serial decoded scanner
using the options in this tab.
Use these settings to ensure that the communication ports on the 8516 match the settings of the serial
devices to which they are connected. If the settings do not match exactly, the devices may not function.
Note: Keep in mind that the effects of previously applied rules must be taken into account when
creating subsequent rules. For example, if the barcode size is important, it should be
checked before any rules that might change the size are applied.
