Barcode length and data security
The reliability of the barcode data transmitted can depend on the
symbologies used—some symbologies are more "fragile" than others
and errors may occur due to incorrect interpretation of code lengths.
For the Interleaved 2 of 5 and Standard 2 of 5 symbologies, the
Define 1 Or 2 Or 3 Fixed Lengths parameters allow you to configure
the MicroBar NX to only accept codes which meet certain length
requirements—the safest option if you know that all the codes in your
application have fixed lengths.
As well as barcode length parameters, other configuration parameters are available for
laser scanners to help to increase the security of the data transmitted (

Each symbology (Interleaved 2 of 5 and Standard 2 of 5) has a different set of
configuration codes for barcode length parameters—you must only use the codes for
your symbology.
