This method is implemented by ASCOM, which requires only a USB cable to control the filter wheel without connecting the camera. First, we need to switch the control port button (shown by the red arrow in the figure below) to implement USB port control. (Observation indicator red light indicates USB control mode)

Use the USB cable to plug into the USB port of the filter wheel and the other end to connect to the computer.
Open the device manager to check the port number (if the driver is installed on the computer, the driver to be installed will be detected automatically, otherwise the 2CP210X driver will need to be installed).
