TouchScreen and Remote Screen Configuration and Calibration
Setting up a standalone station
To set up a standalone station, attach the appropriate
jumpers from the jumper table on page 153, then turn
on power to the system. As the system reboots, you
will notice messages on the screen as the unit config-
ures itself, then the system goes to TouchScreen
calibration.
To calibrate the TouchScreen:
Calibration aligns the internal circuitry of the PC/104
board with the TouchScreen, so that when you touch
an element on the screen, the board correctly inter-
prets which function you wish to accomplish. When
calibrating, be careful not to lean on the TouchScreen
or contact it with anything other than the tool you are
using to touch with (touching with a small, blunt instru-
ment such as the eraser on a pencil works the best).

NOTE: If you should accidentally touch the screen
while you are calibrating it, you must repeat the config-
uration process.
Touch the targets that appear on the screen. Fig. 92
shows all the target points. When you are calibrating
the TouchScreen only one target is visible at a time.
The Current Position field shows the screen coordi-
nates of the target position currently displayed. When
calibration is complete, the system tells you that it is
now okay to turn off the unit. Remove the jumpers,
turn power back on, and you are ready to operate as a
standalone station.
