Rockwell Automation 2755 Enhanced Decoder Series B - Manual (Page 80)

6–7 Configuration: Symbology
Publication 2755-833
This check differs from the one above, because instead of looking
at the number of transitions in the entire scan, this search only
considers the number of transitions contained within the symbol.
The decoder rejects the scan if the number of transitions does not
correspond to a selected specific length. It attempts to decode all
scans if no specific length is specified.
