Parameter # 78
The digital scanner offers four levels of decode redundancy. Select higher redundancy levels for decreasing
levels of bar code quality. As redundancy levels increase, the digital scanner’s aggressiveness decreases.
Scan one of the following bar codes to select the redundancy level appropriate for the bar code quality:
•
Redundancy Level 1 - The digital scanner must read the following code types twice before decoding:
• Codabar (8 characters or less)
• MSI (4 characters or less)
• D 2 of 5 (8 characters or less)
• I 2 of 5 (8 characters or less)
•
Redundancy Level 2 - The digital scanner must read all code types twice before decoding.
•
Redundancy Level 3 - The digital scanner must read code types other than the following twice before
decoding, but must read the following codes three times:
• Codabar (8 characters or less)
• MSI (4 characters or less)
• D 2 of 5 (8 characters or less)
• I 2 of 5 (8 characters or less)
