Currently by default the unit comes as a HID device.
To switch to HID mode (Please note, this may not appear in Game Controllers, but will work in games)
Flick the below switch to RLY CIPHER

Hold the FCS Reset button Down
Flick the same switch to PLAIN the unit will flash.
To switch to DCSBIOS mode (Requires DCSBIOS to be correctly configured)
Flick the below switch to PLAIN

Hold the FCS Reset button Down
Flick the same switch to RLY CIPHER
Currently due to a DCS / HID issue the AUX and Oxyflow knobs do NOT work in HID mode, but they are fully working in DCSBIOS mode, if I find a resolution to this there will be a new firmware available.
Please note the Rud Trim and ILS Channel Encoders Don’t know “where they are” on start-up, so you need to ensure it is in the correct position before plugging it in.
In DCSBIOS Mode the backlight is controlled by the in-game control.
In HID mode The Backlit Brightness is controlled by Pressing FCS Reset and Rud Trim at same time and using the Oxy flow Knob to adjust to desired level.
