Chapter 3: Setting Up D-Control 31
Moving the Keyboard and Trackball
(Optional)
You can move the trackball on the D-Control Main Unit to the
left of the computer keyboard.
To move the keyboard and trackball:
1 Using a 5/64-inch hex wrench, remove the screws in the
computer keyboard panel and the trackball panel on the
D-Control Main Unit.
2 Exchange the position of the trackball and keyboard panels,
and carefully rearrange their cables underneath the panels.
3 Reattach the computer keyboard and trackball panels to the
Main Unit.
Replacing the Trackball with an
External Trackball or Mouse (Optional)
If you prefer to work with your own trackball or mouse, you
can remove the D-Control trackball from the D-Control Main
Unit and replace it with the provided blank plate, and place
your USB-compatible trackball or mouse on top of the blank
plate.
To remove the trackball:
1 Using a 5/64-inch hex wrench, remove the trackball plate
on the D-Control Main Unit.
2 Disconnect the Molex plug from the P1 connector on the
printed circuit board on the bottom of the trackball plate.
3 Disconnect the Molex plug that comes from under the
D-Control keyboard from the trackball assembly.
4 Remove the screws holding the printed circuit board to the
trackball plate. Set the D-Control trackball plate aside.
5 Locate the blank plate and install the printed circuit board
on the underside of the blank plate.
6 Locate the USB connector on the printed circuit board, and
connect your trackball or mouse to it.
7 Connect the Molex plug you disconnected in Step 3 to the
P2 connector on the printed circuit board. Make sure you fit
the connector and plug together correctly (so that the plug
snaps into place) to maintain polarity of this connection.
8 Route the cable of your trackball or mouse through the slot
in the blank plate.
9 Attach the blank plate to the Main Unit.
Reinstalling the Trackball

ball assembly to the P1 connector on the printed circuit board.
Make sure you fit the connector and plug together correctly
(so that the plug snaps into place) to maintain polarity of this
