INSTALLATION AND SETUP
S-Video
The video decoder input panel provides simultaneous connection of both a composite video
source (INPUT 3) and an S-Video source (INPUT 4).
If connecting an S-Video source, use the 4-pin mini DIN connector orthe Y and C BNC con-
nectors (luma and chroma) atINPUT 4-do not use both as inputs. See Figure 2.14.

(line level) audio inputs to the “IN...

INSTALLATION AND SETUP
Video Loop Through
To loop a single incoming video signal input (connected at the video decoder) through to anoth-
er projector or display device, use the empty connector(s) adjacent to this same input as described
below.
Composite Video Loop Through 
CONNECTIONS:See Figure 2.15. From your source, connect a composite video signal to
INPUT 3using either the small phono plug or the adjacent BNC. Connect a second cable from
whichever INPUT 3connector is free to one of the...

INSTALLATION AND SETUP
S-Video Loop Through
CONNECTIONS: See Figure 2.16. From your source, connect an S-video source signal to
INPUT 4using either the 4-pin mini DIN or the 2 adjacent BNCs labeled Y and C. Connect a
second cable from whichever INPUT 4 connector is free to one of the S-video inputs of the next
display device or projector. Continue this looping method for each projector, using either 4-pin
mini DIN or the 2 adjacent BNCs as input into INPUT 4, then using the other connector(s) as an...

INSTALLATION AND SETUP
Extra Video- COMPOSITE OR S-VIDEO 
If you want to use an extra video source in addition to the video source(s) connected at INPUT
3 or INPUT 4connect either a Composite or S-Video source to INPUT 1as shown in Figure
2.17. Do not connect both types here simultaneously. 
NOTE: For additional video inputs, install an optional Composite/S-Video Input Module at
INPUT 2.

INSTALLATION AND SETUP
2.5 Power Connection
Plug the projector’s high-current 13-amp rated line cord into the line input socket located in the
lower right corner of the rear panel of the projector, then plug the 3-pronged end of the line cord
into a grounded AC outlet. Input voltage to the projector must be capable of supplying between
100 and 240 VAC, 50 or 60 Hz. The power source must be capable of supplying 1200 watts of
power to the projector. See Section 5, Specifications for all power...

INSTALLATION AND SETUP
2.8 Zoom, Focus & Lens Offset
Once the projector is properly set up and producing an image, you are ready to make quick lens
adjustments.
Zoom
If you have a zoom lens installed, turn the textured ring of the lens barrel to decrease or increase
the size of the image at the current throw distance. NOTE: Do not touch the lens surface.
Focus
At the lens opening, turn the focus tab until the image is as sharp as possible.
Lens Offset
To ensure that the image is located as...

Figure 2.19. RS-232 Serial Connection to a Computer
RS-422 Ports
Some systems can provide RS-422serial communications (often through a plug-in adapter or
external converter) rather than the more common RS-232. RS-422 communication has differen-
tial “transmits-and-receives” and is generally better suited for long distances than is RS-232 com-
munication. RS-422 is not compatible with RS-232-connecting one to the other could damage the
equipment at either end.
If you wish to...

WARNING 
Do not use an RS-422 port unless you are using a computer with RS-422 capability.
The voltage levels of this signal can damage incompatible equipment.

RS-422 NETWORK:To control multiple projectors with a computer/controller having an RS-
422 interface, you can chain the projectors together by connecting the RS-422 PORT 2connec-
tor of the first projector (already connected to the computer/controller) to the RS-422 PORT 1
connector of the next projector in the chain.

Communication parameters such as baud rate must be set to match the particular controlling
device-refer to the documentation that came with your controlling device in order to determine
the proper baud rate. See 3.7, Adjusting System Parameters and Advanced Controlsif you need
help changing the projector baud rate from its default of 38400.
NOTES: 1)To avoid damage, connect only properly wired serial communication cables. See
