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.
