3.14.7 GS1 DataBar Expanded Security Level 
The engine offers four levels of decode security for GS1 DataBar Expanded 
bar codes. 
 
• Security Level 0 - The engine operates in its most aggressive state, while 
providing sufficient security decoding most in-spec bar 
codes. 
• Security Level 1 - This setting eliminates most misdecodes while 
maintaining reasonable aggressiveness. 
• Security Level 2 - Select this option with greater bar code security 
requirements 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 to apply the highest 
safety requirements.
