GS1 DataBar Limited Security Level
Parameter #
728 (SSI # F1h D8h)
The RS6000 offers four levels of decode security for GS1 DataBar Limited bar codes. There is an inverse
relationship between security and RS6000 aggressiveness. Increasing the level of security may result in reduced
aggressiveness in scanning, so choose only that level of security necessary.
• Level 1 – No clear margin required. This complies with the original GS1 standard, yet might result in
erroneous decoding of the DataBar Limited bar code when scanning some UPC symbols that start with
digits “9” and “7”
• Level 2 – Automatic risk detection. This level of security may result in erroneous decoding of DataBar
Limited bar codes when scanning some UPC symbols. The RS6000 defaults to Level 3, otherwise to Level
1.
• Level 3 – Security level reflects newly proposed GS1 standard that requires a 5 times trailing clear margin.
• Level 4 – Security level extends beyond the standard required by GS1. This level of security requires a
5 times leading and trailing clear margin.
