Installing the display in an Enclosure
The WeatherBright LC3251 and LC4751 are open-frame displays intended to be mounted in a NEMA 3R
enclosure that provides basic protection from the elements. The displays are ruggedized to utilize
outside air for cooling without the need for air conditioning. The enclosure is required to provide an
intake and exhaust for the air cooling with a replaceable air filter. The displays are optically bonded to
4.7mm tempered vandal-resistant cover glass intended for exposure to the elements while providing
the best viewability. It is recommended that the enclosure provide a window opening for the display
with no additional cover glass or window material in front of the display. The ERO™ optically bonded
displays will not experience any fogging, contamination, or reflections that would otherwise
compromise the image viewability over the life of the product.

Connection and Display Power Up
Follow these steps to hook up and power on a LC3251 or LC4751 display.
1. Attach a DVI-D or VGA cable to the corresponding video input of the display.
2. Attach a RS-232 null serial cable to the serial input of the display. A null modem serial cable or
a standard serial cable using a null mode adaptor is required.
3. Attach IEC C14 power cable to the power input of the display. A 6 foot power cable is provided
with the display.
4. Provide power to the display.
Note: The displays do not have an on/off switch. It is acceptable to plug/unplug the IEC C14
power cable at the display to turn power on and off.
On power-up the display backlight will turn on and a Planar splash screen will appear on the display for
10 seconds. The display will then auto-sync to a connected video signal. The display is then ready to
use.
If a video input signal does not exist or there are problems with it a ‘No Input Signal – Going to Sleep’
message will be displayed and the display will go to sleep turning off the backlight. If a valid video
input signal is provided the display will auto-sync to that signal and come out of sleep mode.
