I 2 of 5 Security Level
Parameter # 461h
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 decoder offers four levels of decode security for Interleaved
2 of 5 bar codes. There is an inverse relationship between security and decoder 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 decoder 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 decoder. If this level of
security is required, it is recommended that you try to improve the quality of the bar codes.
