Front and Side View of Monitor
Installation of Monitor
This monitor is intended to be mounted in and used where NEMA 4 and NEMA 12 type
enclosures are employed. When mounted properly, the monitor meets or exceeds the sealing
requirements set forth in the NEMA 4 and NEMA 12 specifications. The monitor uses “U”-shaped clips
and a special gasket to achieve the proper seal.
To install the monitor, make a cutout per the diagram below in one of the walls of your NEMA
enclosure. Enclosures made of heavier gauge metal work better in that they won’t deform or bend as
easily when the monitor’s sealing gasket is compressed. Next hold the monitor in place while you install
the mounting clips. Tighten the clips in a cross pattern. This will help to develop an even pressure on the
sealing gasket. Tighten the clips to the point were the back of the monitor’s front bezel just begins to
contact the front of the NEMA enclosure. DO NOT OVER TIGHTEN AS DAMAGE CAN RESULT IN
THE MONITOR CAUSING LOSS OF SEALING INTEGRITY.
APPLICATION NOTE:
TO REDUCE THE AFTER-IMAGE EFFECTS CAUSED BY STATIC IMAGES BEING
DISPLAYED FOR PROLONGED PERIODS OF TIME, WE RECOMMEND SOME FORM 0F SCREEN
SAVER BE USED.

Mode and Image Adjustment
Not all video controllers produce exactly the same video output levels or the same timing. The
following procedure can be used to select the desired video mode as well as optimize your monitor’s
image quality. When adjusting your monitor, the use of video test software such as DisplayMate for
Windows by SONERA Technologies can be very beneficial.
Before connecting the SXT2010 to your computer, adjust your desk top display settings to the
following:
Colors: 256
Vertical Refresh: 60Hz
Resolution: 1280 x 1024
Monitor Type: Viewsonic 15
After connecting the SXT2010 to your computer you should first adjust the monitors horizontal
size (or width) using the Hsiz menu selection. Next you should use the Hpos and Vpos menu selections
to center the image on the LCD. After this, use the Clka menu selection to focus the screen’s image.
Finally, use the SAVE menu selection to store the monitor’s settings in no-volatile memory.
