The Repository to use is
If you wish to have this unit as a HID device, this can be achieved by pushing the Flaps Switch to Full (Bottom Position), Holding the Warn Tone Sil Button down and flicking Flaps all the way to the Top AUTO in one Push.
The unit will flash and then function as a USB HID Joystick Controller. Please note, this may not appear in Game Controllers, but this will work perfectly fine for any game and will require mapping to be done in most games.
If you wish to switch back to DCSBIOS Mode this can be achieved by pushing the Flaps Switch to Auto (Top Position), Holding the Warn Tone Sil Button down and flicking Flaps all the way to the Bottom FULL in one Push.
Please note the landing gear light will not work in HID mode.
In DCSBIOS mode, When the landing gear is in the “middle” position, if you push both Warn Tone and DN Lock simultaneously this will toggle the Gear Rotate function.
The Backlit Brightness is controlled by the Consoles Rotary.
With the latest firmware, even when in dcsbios mode, The Park Brake is in HID mode and needs manual mapping to function
For mapping see screenshot below in controls, this is how it needs to be mapped, the rest of the controls work in DCSBIOS mode still. Once park brake is rotated and pulled, to release turn right first then push in and it should release.
