ALIBRATING THE
T
OUCHSCREEN
The final installation step is calibrating the touchscreen. Type
"GO" when instructed. Begin the calibration sequence.
You will be prompted to touch three calibration points on the
screen. Before you do so, position yourself in front of the
screen in normal sitting (or standing) position, with normal
height and reach.
Using your finger, touch each of the three points as they
appear in the corners of the screen. The program will
respond with a “beep” sound as you lift your finger from each
point.
Calibration is performed in four common video modes: 80x25
text mode, CGA 320x200 graphics, VGA 320x200 graphics,
and VGA 640x480.
The numerical values for the calibration points for the last
video mode are displayed. X or Y-axis inversion is normal.
If the calibration program does not respond to a touch, check
the cabling, the switch and/or jumper settings on the
controller, and the configuration you selected when installing
the software. Run SETUP to change the configuration.
