A servo actuator controlling system includes a master controller and a number of servo actuators coupled to at least one interface of the master controller. The master controller includes a master MCU and a number of interfaces connected to the master MCU via a first bus. Each servo actuator includes a servo MCU, a first interface coupled to the servo MCU via a second bus, a second interface coupled the first Interface and the serve MCU, a first servo switch connected between the first interface and the servo MCU, and a second servo switch connected between the second interface and the servo MCU. The first servo switch is set to turn on or off the first interface and the second servo switch is set to turn on or off the second interface.

A lighting control system for controlling a cumulative light emitted by a lighting fixture having a plurality of LED light sources may comprise a plurality of LED drivers adapted to be coupled to a respective one of the LED light sources and configured to control an intensity of the respective LED light source, and a controller configured to transmit a single digital message for controlling the cumulative light emitted by the lighting fixture. Each of the plurality of LED drivers is configured to adjust the intensity of the respective LED light source to a preset intensity in response to the single digital message transmitted by the controller.
