Linked axis mode emulates a simple two-axis joystick. Steering acts on the joystick X-axis
and gas and brake pedals work in opposite directions on the ‘Y-axis’. Linked mode is simple
to activate.
1 Disconnect the USB plug from the computer and wait ten seconds.
2 Next hold down one of the buttons or paddles on the wheel while you plug the unit back
into the USB port. Be sure to hold the button down while plugging in and for at least five
seconds after the plug insertion. This will initialize Linked mode.
3 It is important to remember when switching from separated to linked mode or back you
must recalibrate the controller in the Windows Control Panel - Game Controller
routine. Failure to do this will cause improper operation. Do not reboot the computer
when switching modes. The computer needs to be running to initialize linked mode. If
your computer is rebooted for any reason and you wish to use linked mode, you will need
to re-initialize it after restart using the above steps. If no buttons are held down during
initialization, it will always start up in separated mode.
4 Next follow steps 1 through 3 in Section 4.3. After completing these go to step 5 below.
5 A square joystick calibration box will appear. It will prompt you to move the control to the
limits of travel. Turn the steering wheel left and right to its limits. This will move the
crosshair horizontally in the box. Gas and brake pedals will be recognized on the Y-axis,
moving the crosshair vertically in the box. Move both pedals to the limit several times,
release them, and press a button.
6 You will be prompted to verify the center point now. Make sure the wheel is centered and
none of the pedals are depressed. Then press a button to go to the next step.
7 A horizontal box will appear. This will be inactive in Linked mode. Linked mode does not
support clutch operation. If you need a clutch, use Separated mode. Press a button on
the wheel to continue. Two more horizontal boxes will appear. These will be inactive as
long as you are in Linked mode. Just press a wheel button when prompted until you
finish.
8 After finishing select Test. Carefully observe the movement of your controls in the square
box. Make sure that the wheel and each pedal are recognized and operating smoothly to
their limits of travel. If not, recalibrate. In linked mode none of the slider bars will be
active. This is normal. You are now finished.
4.5 CALIBRATION – STAND-ALONE PEDAL UNIT (NO WHEEL)
Calibration of a stand-alone pedal unit is similar to that of a full system except that the control
axis and buttons of the wheel will not be active. They will appear on the calibration screens
but should be ignored. Both separated and linked axis modes are available. Follow the steps
in Sections 4.3 and 4.4 for the mode desired, but keep in mind to click past the wheel
calibration window. If one wants to add button functions to the pedal unit the accessory
expansion port is active. Instructions for adding buttons are provided in section 5.0.
4.6 PROPERLY CALIBRATING THE PMB-II BRAKE PEDAL
The optional PMBII brake mechanism allows you to tailor both the feel and the response of
the brake to your personal preferences. The action of the PMBII allows the brake to be set up
based on pressure applied rather than distance traveled.
