Select whether or not to distinguish between similar characters. (ON*, OFF)
Poor printing quality can cause an 8 to be read as a B. Characters like these are called similar characters. If only
one of the matching characters will exist, Matching similarity can be turned OFF to eliminate discrepancies in
verification results.
There are five sets of similar characters for the this function: B/8, O/D, 0/D, S/5, and I/1.
Example: Character string includes “8”
OFF: 8 will not be matched to the dictionary model for B, its similar character.
ON: Matching will be performed for both the dictionary models 8 and B and the one with the highest similarity
will be the 1st candidate.
Select whether or not to decrease the number of matching
models and increase execution speed.
Normal*: Matching performed against all dictionary models.
High speed: No matching against dictionary models with
vastly different shapes.
Quickest: Matching only against dictionary model for target
character.
Note: This speed setting is ignored if “?” is set for the
characters (OCR mode).
If ? has been set in the character setting (OCR Mode),
select whether bar line characters will be evaluated as
an alphabet “l” or number “1”.
Select whether or not to output to a serial port the 1st candidate character strings. (OFF*, ON)
If QUEST verification results are output using the results output processing items, the character code is output.
If, however, output result is set to ON here, the character string itself will be output to the serial port.
Output format
<unit number>, <region number>, <line number>, <number of characters>, <1st candidate character
string>delimiter.
The asterisk (*) indicates the default setting.
If ? has been set in the character setting (OCR Mode),
select whether ring characters will be evaluated as an
alphabet “O” or number “0”. (The slash zero,
Ø
, will be
read as the number 0 regardless of this setting.)
