Security Level
Parameter # 77
SSI # 4Dh
The scanner offers four levels of decode security for delta bar codes, which include the Code 128 family,
UPC/EAN/JAN, and Code 93. Select increasing levels of security for decreasing levels of bar code quality. There is
an inverse relationship between security and scanner aggressiveness, so choose only that level of security
necessary for the application.
• Security Level 0 - The scanner operates in its most aggressive state, while providing sufficient security
decoding most “in-spec” bar codes.
• 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.
NOTE Selecting this option is an extreme measure against mis-decoding severely out-of-spec bar codes,
and significantly impairs the decoding ability of the scanner. If this level of security is required, try to
improve the quality of the bar codes.
