Hardware: Camera Control - KissUltra/wiki GitHub Wiki

Analog camera control is performed by simulating the joystick controller that is included with the camera. In order to do this, Ultra needs to know the voltages that the factory joystick sends to the cameras to control their OSD.

If you have the camera that is not listed, you can easily measure voltage on joystick wires when pressing the buttons one by one.

The camera control voltages can be configured in Ultra Setup tool:
