Pattern Match String (max. 200 chars)
Click to activate the Text Entry Tool and create a pattern match string.
A Pattern Match String allows the user to check for a sequence of characters in a group of
barcodes. The string can be made up of a sequence of alpha numeric characters combined with
Regular Expression Syntax.
The regular expression algorithms allow checking for conditional barcode information based
on specific expression functions (see below). A pattern matching string is programmable for
each barcode used in the system, and if the barcodes read do not match the defined string, a
No Read Event will be returned.
It is possible to define the matching string by inserting Regular Expressions, including but not
limited to the following:
. – (dot) Matches any character
* - (asterisk) Matches 0 or more of the preceding character.
