Bad/No Symbol Qualification
Dimension Mode (2D Symbology Qualification)
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 dimension. If both
Dimension 1 and Dimension 2 requirements are met, a Bad Symbol message is output. If
both are not met, outputs a No Symbol message.
Object Qualification
Checks first for matches to symbol dimension. If qualified, attempts to decode. If no
decodes are found within the specified read cycle parameters, outputs a Noread mes-
sage.
Enable Both
Same as Object Qualification, except that if neither Dimension 1 nor Dimension 2 quali-
fies, then a No Symbol message is output; if either Dimension 1 or Dimension 2 quali-
fies, then a Bad Symbol message is output.
