SV-D700 / SV-D1000 Installation and Configuration % 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 variable voltage input (0-30VDC), set BRIGHTNESS SOURCE to EXTERNAL OR MANUAL. When this option is selected, dimmingis normally controlled automatically via an external signal, but it can also be controlledmanually by using the Dim Menu. If backlight control is set to external, you must configure thebrightness settings on the Brightness Setup Page. This page displays several parameters, whichare listed and briefly explained 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.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 voltage map. Note that this is a calculated value and is not set by theuser. The actual brightness never drops below 20% when the Brightness Setup Page isdisplayed, even though the target value may be below 20%.% Brightness Voltage–There are four percent brightness values: 25%, 50%, 75% and100%. These percentages are correlated to a brightness voltage, which are to the rightof the percent value. These percentages along with the minimum brightness voltage(explained below) form the calibration points for the backlight management profile.When the current brightness voltage matches one of these points, the target backlightlevel is adjusted to that percentage. When the current brightness voltage is in betweenthese points, the display interpolates between the points and calculates an appropriatetarget backlight level. These voltages must be set by the user.SkyView System Installation Guide - Revision O 4-23
