GS1 DataBar Limited Security Level
Parameter # F1h D8h
The linear imager scanner offers four levels of decode security for GS1 DataBar Limited bar codes. There is an
inverse relationship between security and linear imager scanner 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 scanner defaults to Level 3, otherwise to
Level 3 – Security level reflects newly proposed GS1 standard that requires a 5 times trailing clear
Level 4 – Security level extends beyond the standard required by GS1. This level of security requires a 5
times leading and trailing clear margin.
