Security Level

Parameter # 4Dh

The digital imager 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 imager scanner aggressiveness, so
choose only that level of security necessary for any given application.
•
Security Level 0: This setting allows the digital imager 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 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 bar
codes. Selecting this level of security significantly impairs the decoding ability of the digital imager
scanner. If this level of security is necessary, try to improve the quality of the bar codes.
