SV-D700 / SV-D1000 Installation and Configurationusing the tools on the Brightness Setup Page. This page displays several parameters, which arelisted and briefly explained below.Current Brightness Sensor Value–This is an integer value ranging from 0 to 999 thatrepresents the amount of light sensed by the display’s integrated light sensor. Use thisvalue to characterize the ambient light levels in your installation during characterization.Current Brightness Target–This is a percentage ranging from 0% to 100% that representsthe calculated target backlight level based on the sensed ambient light level and thepercent brightness sensor value map. The actual brightness never drops below 20%when the Brightness Setup Page is displayed, even though the target value may bebelow 20%. % Brightness Sensor Value–There are four percent brightness sensor values: 25%, 50%,75% and 100%. These values are correlated to a user-specified brightness sensor value,which are to the right of the percent value. These percentages along with the minimumbrightness sensor value (explained below) form the calibration points for the backlightmanagement profile. When the current brightness sensor value matches one of thesepoints, the target backlight level is adjusted to its matching percentage. When thecurrent brightness sensor value is in between these points, the display interpolatesbetween the points and calculates an appropriate target backlight level. These valuesmust be set by the user.Minimum Brightness Sensor Value–This is an integer value ranging from 0 to 999 thatrepresents the smallest amount of light that is expected to be sensed by the integratedlight sensor. This must be set by the user.Minimum Brightness–This is an integer value ranging from 0 to 9 that represents thelowest backlight setting when the minimum brightness sensor value is measured by theintegrated light sensor. This must be set by the user.Use the RESET TO DYNON DEFAULTS option to start over if needed. Press BACK to save thesettings and return to the LOCAL DISPLAY SETUP Menu or press EXIT to return to the MainMenu.External Brightness ManagementTo set the backlight level so that it is controlled by an external signal, set BRIGHTNESS SOURCEto EXTERNAL OR MANUAL. When this option is selected, dimming is normally controlledautomatically via an external signal, but it can also be controlled manually by using the DimMenu. If backlight control is set to external, you must configure the brightness settings on theBrightness Setup Page. This page displays several parameters, which are listed and brieflyexplained below.Current Brightness Sensor Voltage–This is the voltage level of the external control signal.Use this value to characterize the ambient light levels in your installation duringcharacterization.SkyView System Installation Guide - Revision J 4-19
