C-95
Security Level
The decoder offers four levels of decode security for delta bar codes, which include 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: This default setting eliminates most misdecodes.

Security Level 2: Select this option if Security level 1 fails to eliminate misdecodes.
