7.1 Control Board Configurations and Option Switches
The Control Board is a microprocessor-based circuit that controls the on-board sensors and the video switcher. The main
purpose of this switcher is to select the Main Video settings to be displayed on screen and then switch the video to either
Light Sensor, Motion Sensor or Switcher Video settings. It may also be directed to ignore the sensors and select one or both
of the Main Video or Switcher Video settings at settable dwell rates.
