Scan-See Sub-Menu – Mapping The Viewport
Follow Cursor
When the "Follow Cursor" parameter is disabled (set to "N"), the cursor is always
assumed to be located at the origin. Using the previous example:
• the area displayed will be (4–9,2–0) to (4–9+9, 2–0+1), or, after clipping
values that are negative or higher than 80: (0,2) to (4,3).
Wraparound
When "Wraparound" is enabled (set to "Y"), the Scan-See display is treated as a
one-line by 20 column display, rather than 2 lines by 10 columns.
Panning
If "Panning" is disabled (set to "N"), the Scan-See viewport does not move when the
cursor moves one position to the right, and the pivot is still inside the Scan-See
display. However, the Scan-See display is updated to reflect the changes within that
viewport. If the pivot goes outside the viewport, or if the 7535 display changes
without the cursor being moved, the viewport is re-synchronized to coincide
the pivot with the anchor.
Line Scrolling
When "Line Scrolling" is enabled (set to "Y"), the Scan-See display is treated as
two separate one line by 10 column displays. The top line always displays the
previous value of the bottom line. In an application where the cursor skips from one
entry field to another, the field that the cursor just entered is displayed on the top
line, and the next field is displayed at the bottom.
Note: When this feature is enabled (set to "Y"), the "Panning" option should be
disabled to prevent updates to both lines after every keystroke
Brightness
The "Brightness" parameter controls the backlight brightness of the display. It only
has an effect on Model 7000 Scan-Sees – scanners equipped with LED (light
emitting diode) displays.
