The following barcodes must be read three times:
Barcode Types “Excluded” Code Length
Codabar 8 characters or less
MSI 4 characters or less
Industrial 25 (Discrete 25) 8 characters or less
Interleaved 25 8 characters or less
Level 4 All barcodes must be successfully read three times before being decoded.
Security Level Select a decode security level appropriate for the barcode
quality when reading delta barcodes such as Code 128,
Code 93, UPC/EAN.
Security Level 0 – This default setting allows the scan
engine to operate in its most aggressive state,
providing sufficient security in decoding most “in-spec”
barcodes.
Security Level 1 – Select this option if misdecodes
occur. This level should eliminate most misdecodes.
Security Level 2 – Select this option if Security Level 1
fails to eliminate misdecodes.
Security Level 3 – Select this option if Security Level 2
also fails to eliminate misdecodes. However, selecting
this option impairs the decoding ability of the scan
engine. If this level of security is necessary, try to
improve the barcode quality.
