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. A no read is sent depending on the
Match/Do Not Match selection.
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.
+(plus) Matches 1 or more of the preceding character.
\d - Matches any single digit
\w - Matches any word character (alphanumeric & underscore).
[XYZ] - Matches any single character from the character class.
[XYZ]+ - Matches one or more of any of the characters in the set.
$ - Matches the end of the string.
[^a-z] - When inside of a character class, the ^ means NOT; in this case, match anything that is
NOT a lowercase letter.
Examples:
Match a code starting with 123 string and followed by any string of characters:
Match String = 123.*
Example Code = 123aC53
Not Matched = 2231c53
Match a code ending with 123 string preceded by any string of characters:
Match String = .*123
Example Code = 41pO123
Match a code having 123 string in any position: 0)
Match String = .*123.*
Example Code = 41pO123253
OPTIONS
Code 128
Enable 7DR Check Digit
Select the check box to enable 7DR Check Digit.
Transmit Start / Stop Char(s)
Select the check box to enable transmission of start and stop characters.
NOTE: For Codabar codes the start/stop characters must be considered in
the match conditions. For all codes which use check digits, if the Check
Digit is transmitted, it must be considered in the match conditions. Input
fields will vary depending on the selected symbology.
NOTE: The 7DR Check Digit is not use with all code symbologies.
