Case Rules
The case rules are defined as follows:
• No rule –
ignored.
• Ma
tch at index – matches the match string at a specified index.
• Ma
tch and replace at index – matches the match string at a specified index and replaces/changes it.
• Rep
lace at index – replaces/changes unspecified data in a given range.
• Add ba
rcode prefix/suffix – adds a global prefix or suffix.
• V
erify barcode size – verifies the barcode size. This rule should generally be assigned first, before creat-
ing subsequent rules.
• Se
arch and replace – replaces all instances of the match string. (Note that this rule cannot fail.)
The information about the status of each case/rule is displayed in the scan log file (see “Scan Log File” on
page 4-91) when enabled. This is useful if a case fails, and you are trying
to determine why a rule is failing.
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 or
der for Omnii to recognize the device connected to the Port Replicator
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.
Baud
Double-tapping on this parameter displays a pop-up window in which you can choose an appropriate rate of
da
ta transfer.
IMPORTANT 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.
