I 2 of 5 Security Level

Parameter #

04h 61h

Interleaved 2 of 5 bar codes are vulnerable to misdecodes by the nature of the symbol, especially when Any

Length is set for Interleaved 2 of 5 bar codes. The linear imager offers four levels of decode security for

Interleaved 2 of 5 bar codes. There is an inverse relationship between security and linear imager

aggressiveness. Increasing the level of security may result in reduced aggressiveness in scanning, so select

only the level of security necessary.

•

I 2 of 5 Security Level 0: This setting allows the linear imager to operate in its most aggressive state,

while providing sufficient security in decoding the most in-spec bar codes.

•

I 2 of 5 Security Level 1: A bar code must be successfully read twice, and satisfy certain safety

requirements before being decoded. This default setting eliminates most misdecodes.

•

I 2 of 5 Security Level 2: Select this option with higher safety requirements to the bar codes if Security

Level 1 fails to eliminate misdecodes.

•

I 2 of 5 Security Level 3: If you selected Security Level 2, and misdecodes still occur, select this

security level. The highest safety requirements are applied. A bar code must be successfully read three

times before being decoded.

NOTE 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 linear imager. If this

level of security is required, it is recommended that you try to improve the quality of the bar codes.
