2.4 Cooling Fans Four (4) thermostatically controlled cooling fans are provided to cool the rear of the display. The thermostat is set to turn the fans on when the video board temperature reaches 30° C. If the display is used in direct sunlight, airflow must be directed across the front of the display or the display LCD fluid may reach its clearing point, then the LC1200R will become temporarily unreadable. 2.5 Connectors There are four connectors supplied as an integral part of the L

2.7 Power Supply The LC1200R does not ship with a power supply. It is recommended that the Planar Systems, Inc. power adapter, part number 997-3066-00 (US) or 997-3067-00 (EU) be purchased with each unit. Refer to Section 5 for power requirements. 2.8 LCD Controller Board The LCD controller board incorporates components necessary to drive the LCD panel. Accepting VGA and VESA video standards (Section 1.2), these video signals are digitized and processed for the LCD panel. Due to t

3.2 Direct Sunlight Operation This monitor will absorb approximately 45 W of solar power on the front surface of the display in a typical setup when facing the sun directly. It is the integrator’s responsibility to design a system that cools the front surface adequately. Otherwise, the display’s LC material will overheat and temporarily phase change. The display will temporarily become black and unreadable. 3.3 Altitude Maximum operating altitude is 3,000 meters [9,850 feet].

defined as a level between 0-mv and 10-mv. The white state (full white) is dependent on the VGA controller driving the LC1200R. Maximum levels may range from 550-mv to 714-mv. Nominal 680-mv input voltage shall be defined as the default for supplier setup requirements. Displayed image intensity and colors will change linearly with the video analog input. This is necessary to provide a uniform user color change on the screen in response to a uniformly stepped analog input. The LC1200

The LC1200R is not damaged by input voltages ranging from 0-vdc to 12.4-vdc. 5.3 Power On-Off Sequences The LC1200R will automatically return to normal operation upon resumption of power after a power loss. 6 User Controls 6.1 LCD Controller Board Controls The display comes from the factory adjusted for the supported modes. When using these modes, adjustment should not be necessary. However, if it should become necessary, or a non-supported mode is selected, the following controls are

The Gain adjustment is to allow the full scale of the input video to be utilized. The direction of this adjustment will reverse when a limit is reached. For example, it will adjust from maximum to minimum, then reverse and go from minimum to maximum. The best way to make this adjustment is with a continuous gray scale pattern on the display. A proper adjustment will give continuous shading from black to white. Auto Adjust: All four parameters (clock, Horizontal position, Vertical positi

6.2.2 Max Bright Jumper The photodiode board can be removed from the system. When the photodiode board is unplugged the LC1200R will default to the minimum brightness mode. If the user would like to display to run at maximum brightness, the MAX BRIGHT, JP1, jumper must be inserted on the inverter board.
