GS1 DataBar Limited Margin Check
Parameter #
728
SSI # F1h D8h
The scanner offers four levels of decode security for GS1 DataBar Limited barcodes. There is an inverse
relationship between the level of margin check and scanner aggressiveness. Increasing the level of margin check
can reduce scanning aggressiveness, so select only the level of margin check necessary.
• Margin Check Level 1 – No clear margin required. This complies with the original GS1 standard, yet can
result in erroneous decoding of a DataBar Limited barcode when scanning some UPC symbols that start
with digits 9 and 7.
• Margin Check Level 2 – Automatic risk detection. This level of margin check can result in erroneous
decoding of DataBar Limited barcodes when scanning some UPC symbols. If a misdecode is detected, the
scanner operates in Level 3 or Level 1.
• Margin Check Level 3 – Margin check level reflects the newly proposed GS1 standard that requires a five
times trailing clear margin.
• Margin Check Level 4 – Security level extends beyond the standard required by GS1. This level of margin
check requires a five times leading and trailing clear margin.
