3.3.2 FOR 2D SCANNERS
By default, the scanner is set to read Interleaved 25 barcodes.
Advanced settings are provided as shown below.
Verify Check Digit
Decide whether to verify the check digit. When desired, select one of the algorithms, USS or
OPCC. If the check digit is incorrect, the barcode will not be accepted.
Transmit Check Digit
The check digit will be included in the data being transmitted.
Cancel the check box if the check digit is not desired.
Convert to EAN-13
Decide whether to convert a 14-character barcode to EAN-13 if the following requirements are
met:
The barcode must have a leading 0 and a valid EAN-13 check digit.
“Verify Check Digit” must be disabled.
Length Qualification
Because of the weak structure of the 2 of 5 barcodes, it is possible to make a "short scan" error.
To prevent the "short scan" error, configure the "Length Qualification" settings to ensure that the
correct barcode is read by qualifying the allowable code length. The barcode can be qualified by
"Fixed Length" or "Max/Min Length".
For "Fixed Length", up to 2 fixed lengths can be specified.
For "Max/Min Length", the maximum length and the minimum length must be specified. The
scanner will only accept those barcodes with lengths that fall between max/min lengths
specified.
