							The projectors arc lamp emits a luminous fluxmeasured in lumens. This flux is
directed at the screen and illuminates it, the illuminance(E) can be measured in Lux
(lumens/m2) or Foot Candles (lumens/ft
2). The illuminanceof the screen is 
calculated by dividing the incident flux by the illuminated screen area.
The brightness of the screen, known as the screen luminance(B) is determined by
the amount of light reflected from it (or transmitted through it if using a rear 
projection screen). If the screen is diffuse, the incident light is reflected into a 
hemisphere. If the screen has a reflectivity(R), the screen luminancein candela/m
2
is given by (R x E) / ¹, where E is measured in Lux. If E is measured in Foot-
Candles, the screen luminanceis in Foot-Lamberts, and is given by R x E.
Examples:
1) A 6 x 4 6 diffuse screen, with a reflectivity of 0.8 is illuminated by a projector
emitting 3000 lumens.
The screen illuminance (E) = F / A = 3000 / 27 = 111 Foot-Candles
The screen luminance (B) = R x E = 0.8 x 111 = 89 Foot Lamberts
2) A 4m x 3m screen with a reflectivity of 0.85 is illuminated by a projector 
emitting 3500 lumens.
The screen illuminance (E) = F / A = 3500 / 12 = 292 Lux
The screen luminance (B) = (R x E) / ¹= (0.85 x 292) / ¹= 79 Candela/m2

							A DMD™ (Digital Micromirror Device™) is a true digital light modulator and
utilises 786,432 (gv) or 1,310,720 (sx) moving aluminium mirrors, with each one
representing a pixel in the final projected image. Each mirror is suspended over
address electrodes by a torsion hinge between two posts. Depending on the voltage
polarity applied, each mirror will either tilt to left or to the right. When light is
applied to the complete DMD™, only the light redirected from a mirror tilting to
the left is projected.
The projector optically filters white light from the lamp into its constituent red,
green and blue. Each colour illuminates a separate DMD™ whose modulated output
is then recombined with the other two to form the projected full colour image.

							The mirrors in the DMD™ are arranged in a 1024 x 768 (gv) or 1280 x 1024 (sx)
array allowing images of all aspect ratios to be displayed. However, the proportion
of DMD™ effectively used will differ depending on the aspect ratio of the image
e.g. a 5 x 4 aspect ratio on a 5100gv would only require the use of 960 x 768 mir-
rors. The diagrams below show the DMD™ usage for each aspect ratio (4 x 3, 5 x 4,
8 x 5, 14 x 9 and 16 x 9) with the shaded areas representing redundant mirrors.

							Up to three HIGHlite Displays projectors can be stacked without any additional 
framing (gravity stacking). One unit can be stacked on top of the other up to three
units. Make sure that each foot is securely seated on the stacking pad.
Connection Instructions
To connect multiple projectors use the supplied DVI-D cable to connect the RGB 
DIGITAL output (INPUT 9) of the master projector to the RGB DIGITAL input of
the slave projector (the second and third stack) until all the projectors are connected.

							Next, using a commercially available, bi-directional RS-232C cable connect the
OPTION OUT terminal of the master projector to the OPTION IN terminal of the
slave projector(s) until all the projectors are connected.
OPTICAL AND MECHANICAL ADJUSTMENT
Place the projectors at the proper height for best screen to projector relationship and
ensure that all projectors have the same display orientation. Next, turn on all the
projectors and display the internal crosshatch test pattern using a different single
colour for each projector e.g. turn on green for the master projector, red for the first
slave projector and blue of the other second slave projector.

							Setting up for Double or Triple Stacking
Adjust the lens shift, zoom and focus to clearly display all projected patterns.
If the vertical alignment of the projector(s) is incorrect, adjust the height of the
feet. If there is any keystone distortion, use Keystone adjustment to correct and
save the settings on each projector.
SIGNAL DATA PREPARATION
When stacking multiple projectors each projector should be configured to display
the input image in exactly the same manner. This requires configuring the master 
projector for each input signal type, adjusting the image and copying it to the slave
projectors using a PC card as follows:
1. Choose one projector to be the master projector and turn it on.
2. Display all the desired input signals adjusting each signal to provide an optimum 
image and place the master projector in standby mode.
3. Remove the PC Card slot decorative panel and insert a PC card into the slot.
4. Press and hold CANCEL, then press POWER on the rear panel of the master 
projector. The POWER indicator will change to steady green and the PC Card 
Access indicator will start flashing. The data will be automatically stored on the 
PC card and the POWER indicator will change to amber.
5. Remove the PC card from the slot of the master projector. With the slave 
projector in standby, insert the PC card into the slot of a slave projector.
Since data in the slave projectors will be lost at this time, make backup copies of
them before proceeding.
6. Press and hold ENTER, then press MENU on the rear panel of the slave 
projector. The POWER indicator will change to steady green and the PC Card
