Control box The transmission control device composed of the control box and its internal components is shown in Figure 7. In order to control the operation of the transmission system, the built-in transformer of the control box provides a regulated power supply for the stepper motor. The controller sends a stable pulse signal to the driver, which converts the signal to an angular displacement and transmits it to the stepper motor. A button capable of controlling the direction of the driver is provided outside the cabinet.
