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...

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...

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...

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...

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...

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...

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...
