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 requirement 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 size. If qualified, attempts to decode. If no decodes are
found within the specified read cycle parameters, outputs a Noread 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.
