Redundancy Level
Parameter # 78
SSI # 4Eh
The scanner offers four levels of decode redundancy. Select higher redundancy levels for decreasing levels of bar
code quality. As redundancy levels increase, the 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 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 scanner must read all code types twice before decoding.
•
Redundancy Level 3 - The 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)
•
Redundancy Level 4 - The scanner must read all code types three times before decoding.
