Security Level
The decoder offers four levels of decode security for delta bar codes, which include the Code
128 family, UPC/EAN, and Code 93. Select increasing levels of security for decreasing levels of
bar code quality. There is an inverse relationship between security and decoder aggressiveness,
so choose only that level of security necessary for any given application.
• Security Level 0: This setting allows the decoder to operate in its most aggressive state, while
providing sufficient security in decoding most "in-spec" bar codes.
• Security Level 1: Select this option if misdecodes occur. This default setting should eliminate
most misdecodes.
• Security Level 2: Select this option if Security level 1 fails to eliminate misdecodes.
• Security Level 3: If Security Level 2 was selected and misdecodes still occur, select this
security level. Be advised, selecting this option is an extreme measure against miss-decoding
severely out of spec bar codes. Selecting this level of security significantly impairs the decoding
ability of the decoder. If this level of security is necessary, try to improve the quality of the
bar codes.
