Security Level
Parameter # 4Dh
The digital scanner 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 digital scanner aggressiveness, so choose only that level of security
necessary for any given application.
•
Security Level 0:
Select this option to allow the digital scanner 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. Select this option if misdecodes occur.
•
Security Level 2:
Select this option if Security level 1 fails to eliminate misdecodes.
•
Security Level 3
: If you selected Security Level 2 and misdecodes still occur, select this security level. Be
advised, selecting this option is an extreme measure against mis-decoding severely out of spec bar codes.
Selecting this level of security significantly impairs the decoding ability of the digital scanner. If you need this
level of security, try to improve the quality of the bar codes.
