1700 Series Wafer Reader Section 3: Configuring a Wafer ID Application
Show Output Graphics
When the Show Output Graphics checkbox is enabled, the character’s score, the read
character, and the center coordinate of the character are displayed in the image area. If
the mark passes, the output graphics are shown in green; if the score is below the Accept
value, the output graphics are shown in red. If a character cannot be read, a question
mark is displayed. If the mark fails, and the character’s score is above the Accept value,
the output graphics for the character are shown in green. An example with Output
graphics enabled is shown in Figure 3-11.
NOTE Output Graphics are only shown when the selected Mark is ‘Chars, SEMI’, ‘Chars, IBM’, or ‘Chars,
Triple’.

Autoscore Non-Alphanumeric (In-Sight 1721/1722 Only)
When the Autoscore Non-Alphanumeric checkbox is enabled, character positions fielded
as dashes (-), dots (.) and spaces automatically score 100 points, rather than a weighted
score based on the quality of the read.
NOTE The Autoscore Non-Alphanumeric option is only available for ‘Chars, SEMI’, ‘Chars, IBM’ and
‘Chars, Triple’ Marks.
