Security Level
Parameter # 77 (SSI # 4Dh)
The digital scanner offers four levels of decode security for delta barcodes, which include the Code 128
family, UPC/EAN, and Code 93. Select increasing levels of security for decreasing levels of barcode
quality. There is an inverse relationship between security and digital scanner aggressiveness, so choose
only that level of security necessary for any given application.
• Security Level 0: This setting allows the digital scanner to operate in its most aggressive state,
while providing sufficient security in decoding most “in-spec” barcodes.
• Security Level 1: This default setting eliminates most misdecodes.
• Security Level 2: Select this option if Security level 1 fails to eliminate misdecodes.
• Security Level 3: If you selected Security Level 2 and misdecodes still occur, select this security
level. Be advised, selecting this option is an extreme measure against mis-decoding severely out of
spec barcodes. Selecting this level of security significantly impairs the decoding ability of the digital
scanner. If you need this level of security, try to improve the quality of the barcodes.
