Eclipser Level Controls
The eclipser function is set at the factory and usually does not need to be readjusted. However, if adjustment is necessary, refer to the section on Eclipser Adjustment in this manual.
THRE
Sets the level for the brightest part of the picture. Anything brighter than this adjustment will be eclipsed.
ECLP
Sets the brightness of the eclipsed area.
GRAY
Sets the brightness of the eclipsed area as viewed on a monitor.
Power Input Terminal
DIP Switch Settings
AGC – Automatic Gain Control
Automatically adjusts the image to compensate for changes in light levels when using fixed or manual iris lenses. Following are the AGC switch settings:
OFF Ð Disables the AGC mode.
ON (Default setting) Ð Enables the AGC mode.
ESC – Electronic Shutter Control
The ESC feature compensates for an excessive light level by automatically adjusting shutter speed. The ESC range is 1:300. Following are the ESC switch settings:
OFF Ð Disables the Electronic Shutter Control mode.
ON (Default setting) Ð Enables the Electronic Shutter Control mode.
NOTE: Set the FL switch to the off position, otherwise ESC will not function.
BLC – Backlight Compensation
The backlight compensation feature compensates for backlit scenes by enhancing objects in the center of the scene that would previously have been in silhouette. BLC will only function with a manual iris lens when the ESC feature is switched on. For direct drive and auto iris lenses, BLC will still function even though the ESC feature is switched off.
Following are the BLC switch settings:
OFF (Default setting) Ð Disables the BLC mode. ON Ð Enables the BLC mode.
ECLP – Eclipser Function
The eclipser function is used with an auto iris lens. When using a CCD imager with an auto iris lens in an area with minimal lighting contrasts, the auto iris lens closes, resulting in poor picture quality. The eclipser function distorts the signal to the auto iris lens, causing the lens to open wider and create sufficient lighting contrasts to prevent the silhouetting of figures. When the auto iris lens used is equipped with a response selector (AVERAGE/PEAK), always set the selector to AVERAGE.
Following are the ECLP switch settings:
OFF (Default setting) Ð Disables the ECLP mode. ON Ð Enables the ECLP mode.
