Modify Settings > Match Codes
Use Modify Settings > Match Codes to define a specific code pattern within
a symbology type that is to be considered a "match condition".
In addition to identifying and reading a symbology you defined (using Modify
Settings > Bar Codes), this feature enables you to configure a reader to
match specific select characters within a bar code.
All bar codes are compared to the complete list of Match Codes. If a bar
code matches ANY of the codes defined in Match Code settings, it is
considered a MATCH. When a match code is read, you can setup your
reader to:
•
fire a relay output (Example: Activate a diverter)
•
send a user-defined message (Example: Acknowledge match code
found)
The following wildcards are available:
•
"*" represents a string with arbitrary length
•
If you enter 9* and the AL5010 reads bar code data 91234567890,
then the AL5010 will transmit a valid read to the host because the
leading 9 matches the pre-defined match character. The rest of the
characters in the bar code are not effected because the asterisk
wildcard instructs the AL5010 that the 9 is the only character that
need to be matched.
•
If the AL5010 reads bar code data 01234567890 then the AL5010
will transmit a no read because the leading 0 in the bar code did not
match the pre-define 9.
•
"?" represents a single character
•
With this condition, the AL5010 will ignore the character located in
the designated location in the data string and only match the
identified data.
See also: Modify Settings > Match Codes in Appendix C .
NOTE: If ANY match code pattern is set to “*” ALL codes will
match it.
