6.4 How to Set the Number of Characters to Read

When you scan barcode labels that have a fixed-length, configure the scan engine to only scan
the number of characters in the barcode. When properly configured, the scan engine rejects
barcodes that are not the specified length. This feature helps ensure the accuracy of scanned
data.
The scan engine only checks the length of the barcode data. Options like transmit start/stop
character and check digit (CD) are not included. Setting the number of characters to read does
not affect fixed-length codes, like EAN-13. ,
