Setting of Number of Characters
6.4
If you are going to read codes of fixed length, it is recommended to configure the scanner for that fixed
number of characters. The scanner will verify that codes read are of the correct length and rejects
codes that do not have the specified length. The advantage of setting a fixed length is that it provides
protection against spurious short scans of codes, possible with code types that do not provide
sufficient security against partial scans (e.g. Interleaved 2 of 5). The length checking is done on the
code data and is not affected by options such as (not) transmit start/stop character or check digit.
Setting the number of characters does not affect fixed length codes, such as EAN-13.
Fixed Length ON, Minimum / Maximum Length for Selected Codes
6.4.1
This option enables fixed length and minimum / maximum length checking for each code types and
will only affect the specified code types.
