2D Symbology Qualification
2D Symbology Qualification
Note: In the cases where Symbol Size Status, Dimension Status, or Orientation Status
is enabled, the Imager will always check the finder pattern regardless of Finder Patter
Status setting.
Finder Pattern Status
Symbol Size Mode (2D Symbology Qualification)
Note: If Symbol Size 1 is larger than Symbol Size 2, it will be automatically reversed in
the algorithm.
Disabled
Decoded messages are output, but no attempt to qualify symbols or output Bad or No
Symbol messages is undertaken.
Bad/No Symbol Output
Checks first for decodes. If no symbol is decoded, checks for symbol size. If both Symbol
Size 1 and Symbol Size 2 requirements are met, a Bad Symbol message is output. If
neither are met, a No Symbol message is output.
Object Qualification
Checks first for matches to symbol size. If qualified, attempts to decode. If no decodes are
found within the specified read cycle parameters, outputs a No Read message.
Enable Both
Same as Object Qualification, except that if no objects qualify, then a No Symbol message
is output; if at least one object qualifies, then a Bad Symbol message is output.
Definition: Checks for the presence of a finder pattern.
