Steering PAD 900-F

Check LOG bellow for changed parts!

_
INTRODUCTION

This controller is a 3-axis + 15-button HID, designed with Euro Truck Simulator 2 in mind. It also works with other games.
The steering wheel has 900 degrees of rotation and force feedback, and the two pedals are analog.

Of the 15 buttons, 6 have special functions:
- Two are turn signal indicators.
- The ignition key slot functions with a rotating motion.
- The plus and minus buttons are each assigned to two functions. To access the second function on each, hold the cruise control button while pressing plus or minus.
- The T button is triggered on release, as holding it activates the configuration menu.
All other buttons are standard and trigger on press.

The key is removable and can be used to lock the pedals down, preventing them from being pushed or damaged when transporting the controller in a backpack.

The face of the steering wheel is removable by pulling it out. It is held in place with a magnet and three alignment pins, so it stays secure and can’t be mounted incorrectly.
