Here's the wiring data on the ***OLDER*** CH Flightsticks, to see how they map out relative to standard PC Joysticks. You can use this as a basis for understanding how other standard PC joysticks would work with the OI.

The CH Products Flightsticks are using the old DB-15M PC Joystick standard. They are NOT USB, so don't try to buy a USB stick to work with the OI.

- Full Forward, Full Left and Thumbwheel forward are lowest resistance settings.

Someone please correct me if I'm wrong, but I *think* that translates to minimum byte values in the default program...

- All three pots are roughly 90K +/- 5%, run in "Rheostat Mode", with one end of the main element being the "signal", and the wiper tied to +5V on pin 1. (seems backward to me, but the pot doesn't care...) Any 100K pot based joystick wired in this way will be an acceptable equivalent.

PC Joystick Standard equivalency:
- Left/Right (X) signal = "PC Joystick Pot X1" on pin 3.
- Forward/Back (Y) signal = "PC Joystick Pot Y1" on pin 6.
- Thumbwheel = "PC Joystick Pot Y2" on pin 13.

- All switches are commoned to both pins 4 and 12 (two of the three standard PC switch grounds). Note this does NOT exactly conform to the PC Joystick Standard, but since most manufacturers tie all three grounds together anyways, it normally doesn't matter.

- Trigger switch = ""PC Joystick Switch 1" on pin 2.
- Top Hat switch = "PC Joystick Switch 2" on pin 7.

- The cable is shielded, and terminated only on the case of the DB-15M connector.

- All other pins unconnected.

The PC Joystick Standard:

Pin: Signal
1: XY1 (+5V)
2: Switch 2
3: X1 (pot)
4: Ground (for Switch 1)
5: Ground (For Switch 2)
6: Y1 (pot)
7: Switch 2
8: N/C (Not Connected)
9: XY2 (+5V)
10: Switch 3
11: X2 (pot)
12: Ground (3&4)
13: Y2 (pot - In this case the Thumbwheel)
14: Switch 4
15: N/C

I haven't checked out the NEW sticks yet to see which is which, but I'm sure at LEAST the X/Y (main stick) pots and the trigger are the same connections.

If someone has already reversed engineered the new sticks, please post their wiring diagram here. Thanks!

I hope this helps!
