Joypad for Elite gen 2 instructions

I have a new joypad I bought from onefinity for my Elite gen2. I use a Win 11 computer to run controller. I cannot find instructions other than for the HMI or old ones that use a different controller. I gave a redline and PS-600. Has anyone discovered the necessary guidance.

It’s so simple it almost warrants no instruction. Plug in the usb dongle before you launch the windows/mac RTX software, power on the joypad with the button on the controller, then boot up RTX software.

Thank you! I will try that start sequence
