Security Level
Parameter Default Value: Security Level 1
The decoder offers four levels of decode security for delta barcodes, which include the Code 128
family, UPC/EAN, and Code 93.
Select increasing levels of security for decreasing levels of barcode 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” barcodes.
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 mis-decoding severely out of spec barcodes. 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
barcodes.
Select the security level appropriate for the barcode quality and then scan the appropriate Security
Level barcode on this page and the following page.
Security Level 0
Security Level 1
