Level of Linear Code Consistency Verification (0x4E)
This parameter offers 4 levels of decode security for linear code types (e.g. Code 39, Interleaved
2 of 5). Select higher security levels for decreasing levels of bar code quality.
As the security levels increase, the scanner’s aggressiveness decreases. Select the security level
suitable for the bar code quality.
Note: Symbols such as UPC or EAN are not applicable to this parameter.
