I 2 of 5 Security Level
Parameter # 1121
SSI # F8h 04h 61h
Interleaved 2 of 5 barcodes are vulnerable to misdecodes, particularly when I 2 of 5 Lengths is set to Any Length.
The scanner offers four levels of decode security for Interleaved 2 of 5 barcodes. There is an inverse relationship
between security and scanner aggressiveness. Increasing the level of security can reduce scanning
aggressiveness, so select only the level of security necessary.
• I 2 of 5 Security Level 0: The scanner operates in its most aggressive state, while providing sufficient
security in decoding most in-spec barcodes.
• I 2 of 5 Security Level 1: A barcode must be successfully read twice, and satisfy certain safety
requirements before being decoded. This default setting eliminates most misdecodes.
• I 2 of 5 Security Level 2: This option applies greater barcode security requirements if Security Level 1
fails to eliminate misdecodes.
• I 2 of 5 Security Level 3: If you selected Security Level 2, and misdecodes still occur, select this security
level. The highest safety requirements are applied. A barcode must be successfully read three times
before being decoded.
NOTE: Selecting this option is an extreme measure against mis-decoding severely out-of-spec barcodes,
and significantly impairs the decoding ability of the scanner. If this level of security is required, try to
improve the quality of the barcodes.
