1 Before you begin

A few words about the Cyberscreen ® technology

Your Brilliance 201CS has put a milestone in CRT color display technology. Thanks to its unique DDA (Digital Dynamic Adjustment) system, color, brightness and convergence are digitally optimized over the entire screen, providing an out standing sharp, precise and uniform image.

The built in correction system divides the whole screen into a 16x16 virtual matrix (@ 1024*768 resolution) and for each of the resulting 256 areas the image can be refined for both brightness and color uniformity, as well as for convergence. In other words, the monitor electronics is able to compensate for the lack of perfor mances of the current Cathode Ray Tube technology.

In addition, the Brilliance 201 CS features a patented ‘magnetometer’ system that automatically detects and compensates for any variation in the Earth Magnetic field conditions, so that the superior performance of your display wilt be maintained under any installation environment.

With its uncompromised image quality, the Brilliance 201 CS has been designed to fully satisfy the increasing demands for ‘state of the art’ display performances, coming from todays most powerful professional applications, like CAD/CAM/CAE, Desktop Publishing, Color Prepress, Advanced Imaging and graphics intensive busi ness applications.

Before you begin

The LP21 -2 Light Probe enhancement

Specifically designed for the operation with the 21” Cyberscreen ® display, theLP21

-2 calibration package offers a precise, PC based adjustment of color/ brightness uniformity as well as for convergence, for fast on-site recalibration and maintenan ce of your display.

In other words, this product enables you to compensate any drift that may occur due to the aging of the picture tube, maintaining the superior performances of your display over the product lifetime.

The calibrator system is based on a precision, high sensitivity light probe that com municates with both the monitor and your computer thanks to a built in RS 232 inter face provided to offer the maximum connection flexibility.

The Windows based software package provides an intuitive GUI (Graphic User Interface) operation, so that you can start right now working with your new LP21 -2 Light Probe.

Getting started

Installing the hardware

STEP 1 Choose a comfortable and secure location for the Light Probe unit, making sure that the interconnection cables can reach both the monitor and the computer. Check that either the device or the cables will not interfere when you tilt and swivel your moni tor.

CauYioN: do not place the Light Probe unit on top of your monitor.

If you obstruct the air flow coming from the cabinet ventilation slots both the moni-

tor and the Light Probe unit can be damaged by excessive overheating.________________

CAuTloN: To prevent possible damage to equipment, both the computer and moni-

tor must be turned off before connecting or disconnecting any cable. When connecting a cable, perform the operation carefully making sure that con-

nectors are well aligned during insertion.

STEP 2 Connect the cable having the 9 pin D - subminiature plug in type connector (male) to the connector labeled SERIAL INTERFACE located on the back of your monitor.

STEP3 Connect the other end of the cable to the output port of the Light Probe unit, which is marked as follows on the bottom of the unit:
