							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

							You can use your projector to project an image from either in front or
behind the screen. The Projector can either be set for either ceiling mounted
front/rear projection or desk mounted front/rear projection using the Projector
Options > Setup > Page 1 > Orientation menu option.
The throw distance required for rear projections is the same as for front projection.
If the image is inverted when projecting an image from the rear onto a transparent
screen, it can be corrected using the Orientation feature under Projector Options >
Setup > Page1 in the Projector Options Submenu. 
Only use your projector on a solid, level surface. Installing your projector on a 
ceiling must be done by a qualified engineer. If the projector falls to the ground, you
can be injured or the projector may be damaged.
Up to two projectors can be gravity stacked without external support to increase the 
brightness of the displayed image. In some cases, the two images will not align 
correctly and may need adjusted. This will be more apparent when displaying small
text and graphics. Refer to page DÑ8, Gravity Stacking, for more information.
In order to prevent any damage to the projectors, they should be securely 
mounted on a shelf or table that has sufficient strength to support the weight of
all the projectors.
STACKING THE PROJECTORS
Place the projectors at the correct height for best screen to projector relationship and
ensure that all projectors are set to the same display orientation.

							HOOK-UP
Using an RGB signal cable, connect the RGB output of the master projector to the
RGB input of the slave projector (an RGB cable is supplied with the SHOWlite
4000gv projector). Repeat the procedure with the output from the slave projector
until all additional slaves are connected.
Using a commercially available, bi-directional RS-232C cable connect the PC
CONTROL OUT terminal of the master projector to the PC CONTROL IN terminal
of the slave projector. Repeat the procedure with the out terminal from the slave
projector until all additional slaves are connected.
Turn all projectors on and and adjust the optical parameters of each projector until a
desirable image is displayed.
SIGNAL DATA PREPARATION
Select one projector as the master projector and turn it on. Next, display all the
desired input signals, making adjustments where required and then save the changes
to the master projector. Turn the master projector off and store all the adjustments to
the master projector to a PC card.
It is not possible to register signals whilst in Link Mode, this procedure has to be
completed before proceeding.
STORING DATA ON A PC CARD
Insert a PC Card into the PC Card slot on the master projector. Press and hold 
CANCEL, then press POWER on the top panel of the master projector. The power
indicator will change to a steady green and the PC Card Access indicator will start
flashing.
After storing data on the PC Card, the Access indicator will change to orange.
Remove the PC Card from the master projector and transfer the data from the 
master projectors PC Card to the slave projectors.

							TRANSFERRING DATA FROM A PC CARD
Insert the PC Card into the PC Card Slot of the slave projector. Press and hold
ENTER, then press MENU on the top panel of the slave projector. The POWER
indicator will change to steady green and the PC Card Access indicator will start
flashing to indicate that data is being copied to the slave projector. 
After storing data on the PC Card, the Access indicator will change to orange.
Remove the PC Card from the slave projector.
If you selected RGB1 as the input on the master projector, you must also select
the same input on the slave projector.
After adjusting and registering the signals as mentioned above, you must change
the input to RGB on the Entry Edit Command window for Link Mode. 
ADJUSTING THE DISPLAYED IMAGE.
Display the internal crosshatch test pattern using a different colour for each 
projector and adjust the lens shift, Zoom and Focus until a clear image is displayed.
If the physical (vertical) alignment is not correct, adjust the height of the 
projector feet. If there is any keystone distortion, use keystone adjustment to 
correct and save the settings on each projector. 
This completes the installation for stacked projectors. The user must now configure
the link mode to allow multiple projector control.

							Link Mode Setting
To configure multiple projectors for Link Mode you must define a unique projector
ID for each projector, set the Communication Speed and define whether each 
projector is a Master or Slave.
The projector ID for a 3000sx projector is assigned under Projector Options > Setup
> Page 5 > Projector ID. For a 4000gv projector it is assigned under Advanced
Menu > Projector Options > Setup > Page 6 > Projector ID.
The Communication Speed is located on the same Setup page. All projectors should
be set to the same speed (available options are 4800, 9600, 19200 and 38400).
Link Mode is located under Projector Options. The master projector should be
defined as ÔMasterÕ and all other projectors should be defined as ÔSlaveÕ.
Once the Link Mode settings have been defined, display an image onto the screen
and check to ensure that the images from all the projectors are synchronised, 
adjusting for any differences in vertical alignment or keystone distortion.
If you select an unregistered signal, the master projector will display the image
but the slave projectors will not. It is not possible to register an image whilst in
Link Mode. To register a signal, set Link Mode to ÔStandaloneÕ and repeat the
multiple projector operation procedure from Signal Data Preparation. 
To make any image adjustments to slave projectors, temporarily change the master
projectors Link Mode setting to ÔStandaloneÕ and check that all other projectors are
in slave mode. Next, display the same image source on all projectors and make any
desired adjustments to brightness, contrast or colour temperature of the slave 
projectors. Finally, change the Link Mode of the master projector back to ÔMasterÕ
to activate Link Mode
The setup procedure for Link Mode has now been completed.

							Gravity Stack
Up to two projectors can be gravity stacked without external support. In some cases
however, the projected images will not align. This will be more apparent when 
displaying small text and detailed graphics.
The optional lenses available for the projector have different geometrical distortions
in wide zoom and tele. Select the best zoom position for stacking where the 
distortion is a little as possible (see System Installation, page BÑ5 for Lens Throw
Distances).
The horizontal lens position must be as close to the centre of the lens opening as
possible.
A distribution amplifier is recommended for gravity stacking in Link Mode to 
distribute one input source to two projectors. Without a distribution amplifier, the
horizontal position of each projector will need to be adjusted before enabling Link
Mode. This adjustment will prevent image alignment.
Operation via Remote Control
Multiple projectors can be individually controlled by the same remote control by
assigning each projector a unique ID number and specifying the ID number of the
projector you wish to adjust.
To assign the ID number on a 3000sx projector, select Projector Options > Setup >
Page 5 > Projector ID. For a 4000gv projector, select Advanced Menu > Projector
Options > Set Up > Page 6 > Projector ID.
To operate a specific projector, press and hold the CTL button on the remote control
then enter the ID number of the projector you wish to operate.
Specifying ÔNoneÕ for the projector ID allows you to operate multiple projectors
concurrently. However, some projectors may not synchronize to the others.

							WIRED OPERATION
You can daisy chain multiple projectors and operate them individually via a single
hard wired remote control.
First, connect the REMOTE 2 output of the first projector to the REMOTE 2 input
of the second projector using a remote control cable (only one supplied with each
projector). Repeat the process until all projectors are linked.
Next, assign a unique ID number to each projector and operate using the remote
control as normal. The ID number can be set to ÔNoneÕ allowing multiple projector
control (see operation via remote control on previous page).
Operation via the PC Control Connectors
The Link Mode function allows you to adjust or set multiple projectors using the
RGB 2 and PC CONTROL connectors. 
Using a bi-directional RS-232C cable (not supplied) connect the PC CONTROL
output of the master projector to the PC CONTROL input of the slave projector.
Next, using the supplied RGB signal cable, connect the MONITOR OUT of the
master projector to the RGB2 connector of the slave projector.
It is recommended that a commercially available distribution amplifier is used if
connecting multiple projectors in Link Mode. For more information on PC Control
see page DÑ16.
