WICO C om m and C ontrol Joysticks are switch-type and give only d ire c
tional readings. They can be used with any software program that utilizes
joysticks for direction only (not for screen position). When properly
connected, the joysticks give output readings of 0, 128, and 255 for
both vertical and horizontal directions.
NOTE: The adaptor is factory-adjusted to a center point of 128. However,
some adaptors may need readjustment due to com puter hardware varia
tions. To adjust: unscrew the 2 cover screw s and remove the adaptor’s
top cover, then locate the 4 trim pots used to adjust the center value
of each joystick. (See diagram.) Below is a basic program displaying
the joystick values. With the jo ystick handle in the center position,
adjust each pot until the figure “ 128” is displayed. After centering,
movement of the jo ystick handle should display values of “ 0 ” or “ 255”
and pressing the fire button should display the “ Fire Button” message.
