2.3.3 Scanning Parameters
Conditions that allow scanning a symbology in specific modes can be set for each readable
symbology.
Readable Symbology
Bar code symbologies that are enabled or disabled for scanning can be specified. If only specific
symbologies are to be scanned, set “Enable” for scanning on these symbologies only and
“Disable” on the other symbologies. This reduces decode processing time and lowers the error
rate. The default is “Enable scanning on all the symbologies”.
Readable Digits
The no. of readable digits can be set for each symbology. If only specific no. of digits is to be
scanned, specify it for each readable symbology. This reduces decode processing time and lowers
the error rate.
Enable or Disable Check Digit
Check digit can be set to “Enable” or “Disable” for each readable symbology. Setting the check
digit will lower the error rate.
