Barcode length
The minimum length possible for Interleaved 2 of 5 is 2 characters:
[barcode data + check digit if applicable]
Interleaved 2 of 5 always encodes an even number of characters. To handle codes with an
odd number of characters, the ScanPlus will accept a code with the last character printed
as 5 narrow bars. In this case, all useful characters are transmitted.
For maximum security, we strongly recommend that you use one of the following
parameters with all ScanPlus products:
•
Compose 1 or 2 Fixed Lengths (the safest configuration),
•
Compose Minimum Length.
Compose 1 or 2 Fixed Lengths provides the best security if the codes in your application
have fixed lengths.
Compose Minimum Length is recommended if the codes in your application do not have
fixed lengths.
Use the special number codes provided on the back cover of this Installation Guide and
scan End Selection once or twice as required.
