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.
