4.21.3.1

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.
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.
Translation information about the status of each case/rule is displayed in the scan log file (see "Scan Log
File" on page 99) when enabled. This is useful if a case fails, and you are trying to determine why a rule
is failing.

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 Omnii 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 that some devices can auto-detect serial port settings (such as baud rate), and in this case Omnii will
dictate the settings. Baud rates often have a direct impact on performance—they should be set as high as
possible while still ensuring reliable communication.
4.21.4.1

Port Replicator Port A (COM5) and Port B (COM6)

Port Replicator Port A (COM5) and Port B (COM6) are standard RS-232 DE-9 DTE ports on the Omnii port
replicator module, available on some snap modules and cradle types.
Enabled
This parameter must be set to ON in order for Omnii to recognize the device connected to the Port Replica-
tor 9-pin (COM5).
Power (COM6 only)
Pin 9 on Omnii COM6 is reserved for 5V power out and is defaulted to OFF. This parameter must be set to
ON to enable power to a Snap Module or Vehicle cradle.
