I use an X on 4x 360s (older and mix of them). I have them connected to the 0-10v port and have no issues. I do have to power the controller via a USB, as opposed to powering it from the k-link from the light.
With that said, you will need
1x controller
1x USB power brick (5v/1A) (I used an old phone brick)
1x USB to micro USB cable to run from the brick to the controller (I used an old phone cable lol)
1x (more if multiple lights are used) 0-10v cable aka 1/8" (3.5mm) stereo male phono plug to 1/8" (3.5mm) stereo male phono plug. I went with a 5 pack off Amazon for cheap and they work just fine.
Connect the power brick/usb cable to center port on controller, then plug the 3.5mm cable into the 0-10v port, then into the light input, set the controller up and good to go. Just setup the light in the 0-10v menu in the dashboard.
