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 83) when enabled. This is useful if a case fails, and you are trying to determine why a rule
is failing.
4.20.4
Ports
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 VH10 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 the VH10
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.
4.20.4.1
Ports
The two serial ports (COM1 and COM2) are standard RS-232 DB-9 ports.
Enabled
This parameter must be set to ON in order for the VH10 to recognize the device connected to the
serial port.
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.
