Installation

5.Make sure the appropriate BNC cable is used. Should the graphics adapter require a connector other than the 15 pin mini D-sub male included with the monitor, please call NEC at (800) 820-1230. Connect cable to system.

6.Connect BNC cables as follows according to the input video mode selected above. (Note: incorrect cable connections may result in irregular operation, damage display quality/ components of LCD module, and/or shorten the module’s life.)

Connect the red BNC cable to the BNC connector on the monitor labeled R. The green BNC cable should be connec- ted to the BNC connector on the monitor labeled G. The blue BNC cable should be connected to the BNC connector on the monitor labeled B. If you have a fourth BNC connec- tor (Composite Sync), connect it to the BNC connector on the monitor labeled H/CS. If you have a fifth BNC connector (Vertical Sync), connect it to the BNC connector on the moni- tor labeled VS. Please see Appendix 1 for pin assignments.

7.Connect one end of the power cable to the LCD1280 monitor and the other end to the power outlet.

8.Turn on the monitor and the computer.

Note: If the settings and connections were made properly, the LED on the front of the LCD1280 will show green.

If the LED displays an amber color, the monitor is not receiv- ing the appropriate input. Please make certain that the above settings were made properly. If the LED continues to display an amber color or the monitor is not displaying a stable image, please refer to the Troubleshooting section of this manual.
