Wiring diagram

Although it would be ideal to present a uniform wiring diagram, this isn't as straight forward as it might seem. The pinout of the IBM PC joystick port is as follows:-

The wiring in the 'Y' cable that you will need to make will be dependent on your present joystick. If your joystick is a basic 2 axis joystick then the cable is straightforward. However, if you have a joystick which has a throttle, then you will need to ensure that the wiring for Joystick A also includes the connections for the throttle which will normally be the Y Coordinate of Joystick B.

I use my pedals in conjuction with either a Zoomer Yoke, a QuickShot with throttle and/or a PC Flight Force fire control system.

Additional information regarding the CH Virtual Pilot Pro has come to light. I don't claim to be the source for it and haven't had time to format it for the web page so in the mean time here it is!

Pin Function Pin Function
1 +5v 9 +5v (SB midi)
2 Joy A, Button 1 10 Joy B, Button 1 (multibutton 3)
3 Joy A, Direction X 11 Joy B, Direction X
4 Gnd 12 Gnd (SB midi)
5 Gnd 13 Joy B, Direction Y
6 Joy A, Direction Y 14 Joy B, Button 2 (multibutton 4)
7 Joy A, Button 2 15 +5v
8 +5v

Each switch grounds the respective pin. X and Y are wired via 100kohm variable
resistor to +5V.
Throttle: Joy B, Direction Y
Pedals: Joy B, Direction X

In order to achieve 2 pedals, connect 2 separate 50kohm variables in series.

50 kohm 50 kohm
GND o------|\/\/\/\|---+---|\/\/\/\|------o +5 V

Right up equals 50 kohm,
Right down equals 0 kohm,
Left up equals 50 kohm,
Left down equals 0 kohm,

CH Virtualpilot pro and F-16 comp.stick buttons:

X X X Hat 1 Down
X X X Hat 1 Right
X X Hat 1 Left
X X X Hat 2 Up
X X Hat 2 Down
X X Hat 2 Right
X X Hat 2 Left

A = switch has connection to Pin 2 trough a diode.
B = switch has connection to Pin 7 trough a diode.
C = switch has connection to Pin 10 trough a diode.
D = switch has connection to Pin 14 trough a diode.

Example: ``Hat 1 Left'' is "A" + "B"

S1 ___ D1
GND o------o o--+----|<|----o Pin 2 (Button 1)
| D2
+----|<|----o Pin 7 (Button 2)
V You can use the above for other "Hat 1" buttons
~ as well, by placing a diode here.

Diodes D1,D2: anything you have, e.g. 1N 4002 (for heavy-duty use ;)
