Security Level - Motorola DS9208-1D Product Reference Manual

Security Level

Parameter # 4Dh
The digital scanner 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 digital scanner aggressiveness, so choose only that level of security
necessary for any given application.
•
Security Level 0: This default setting allows 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 setting eliminates most misdecodes.
•
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.
