Changing Symbology Settings
3.3 CODE 25 — INTERLEAVED 25
3.3.1 FOR 1D SCANNERS
By default, the scanner is set to read Interleaved 25 barcodes.
Advanced settings are provided as shown below.
Start/Stop Selection
Select a desired start/stop pattern.
Verify Check Digit
Decide whether to verify check digit when decoding Industrial 25 barcodes. 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.
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.
