1.1 Projector
Overview

Section 1: Introduction
1-2 User’s Manual
The projector accepts data/graphics and video input signals for projection onto front
or rear flat screens. High brightness light is generated by an internal Xenon lamp then
modulated by three DMD (digital micromirror device) panels that provide digitized
red, green or blue color information. Light from the “on” pixels of each panel is
reflected, converged and then projected to the screen through a single front lens,
where all pixels are perfectly superimposed as a sharp full-color image (2D or 3D for
Mirage models only).
The following listed items are shipped with your projector. Ensure you have received
all these items before using your projector.

Installation & Setup
User’s Manual 2-1
The instructions provided here are for those that are familiar with the projector and
wish to quickly set it up and use it temporarily. Refer to the remaining subsections of
this manual for a more complete setup.
Install a Projection Lens
The projection lens is shipped separately from the projector and must be installed
prior to setting up the projector. Install the projection lens as described in 4.5
Replacing the Projection Lens.
Remove the lens plug from the lens opening in the projector before installing the
lens.
Remove the lens when shipping the projector and reuse the lens plug to prevent
dust and debris from entering and settling on the projector’s optical components.
Position the Projector
Place the projector on a sturdy, level surface and position it so that it is perpendicular
to the screen at a suitable distance. In general, the further back the projector is
positioned from the screen, the larger the image will be.
If required, you can level the projector by adjusting its three feet. With the projector
positioned perpendicular to the screen the image will appear rectangular instead of
keystoned.
For more detailed instructions on positioning the projector refer to Projector Position
and Mounting later in this section.
Connect a Source
Located at the back of the projector is the input panel where all source connections are
made. Each input is clearly labeled for easy identification.
Using the appropriate cable(s), connect your source. Connect RGB and YPbPr sources
to INPUT 1 located in the upper right corner of the input panel. Use the DVI-I
connector at INPUT 2 to connect analog or digital display signals. Connect composite
video to INPUT 3 and S-video to INPUT 4. NOTE: One of the available optional input
modules can be installed at INPUT 5 or INPUT 6 for additional connections.
Refer to 2.3 Connecting Sources for more details on connecting a specific source.

Connect the Line Cord
The North American rated line cord is provided with each projector.
Plug the line cord to the AC receptacle located on the right hand side of the projector
and the 3-pronged end into a grounded AC outlet. The input voltage to the projector
must be capable of 100 – 240 VAC in 500W and 1000W models and 200-240VAC in
1200W models. (See also Section 6 – Specifications for complete details on all power
requirements.)
Use the approved North American-rated line cord supplied with the projector. If you
are connecting to an area outside of North America make sure you are using an
appropriately rated line cord.
Turn the Projector ON
Press the POWER button on either the remote or built-in keypad to turn the
projector on. Wait a few minutes to allow the projector to warm up. The LED status
window displays an active pattern of segments to indicate the projector is changing its
state from powered down to powered up. The message “On” appears in the display
when the projector has completed its initialization and is ready for use.

• Installation cost is usually higher
Rear Screen, Inverted Mount (ceiling) Installation
ADVANTAGES CONSIDERATIONS
• Projector is completely hidden
• Usually good ambient light rejection • Requires separate room • Installation cost is usually higher
Rear Screen, Floor Mount with Mirror
ADVANTAGES CONSIDERATIONS
• Projector is completely hidden
• Usually good ambient light rejection
• Requires less space behind screen than
other rear screen installations
• Requires separate room
• Installation cost is usually higher
Front Screen Installations
In front screen installations the projector and audience are positioned in front of the
screen, which can be flat or curved.
Flat screens are most recommended with this projector. They offer a gain of about 1
with a viewing angle just less than 180°. This type of screen reflects incident light
equally in all directions so the audience can see the display from various angles.
Curved screens have a gain greater than 1 with a viewing angle much less than 180°.
This type of screen does not reflect incident light equally in all directions instead it is

concentrated in a viewing cone. The audience sitting within the viewing cone area will
see a brighter image than those sitting just outside this area.
Rear screen installations
There are two basic types of rear screens: diffused and optical.
A diffused screen has a surface, which spreads the light striking it. Purely diffused
screens have a gain of less than 1. The main advantage of the diffused screen is its
wide viewing angle, similar to that of a flat screen for front screen projection. This
type of screen is suitable when a wide viewing angle is required but there is low
ambient room lighting.
Optical screens take light from the projector and redirect it to increase the light
intensity at the front of the screen. This reduces it in other areas. A viewing cone,
similar to that of a curved front screen installation is created. This type of screen is
better suited for brightly lit rooms where the audience is situated within the viewing
cone.
Screen size
Choose a screen size, which is appropriate for your lens and application. Keep in mind
that if the projector will be used to display text information, the image size must allow
the audience to recognize all text clearly. The eye usually sees a letter clearly if eye-
to-text distance is less than 150 times the height of the letter. Small text located too far
from the eye will likely be illegible at a distance no matter how sharply and clearly it
is displayed.
To fill a screen with an image, the aspect ratio of the screen should be equal to the
aspect ratio of the image (expressed as the ratio of its width to its height). Standard
video from a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR

Section 2: Installation and Setup
User’s Manual 2-5.
output with a 4:3 aspect ratio onto a 10-foot (3m) high screen, the width of the screen
must be at least 13.3feet (4m).
The high brightness of this projector is well suited for locations where ambient
lighting might be considered less than ideal for projection. A typical room with ceiling
lights and windows rarely requires special attention. Contrast ratio in your images will
be noticeably reduced only if light directly strikes the screen, such as when a shaft of
light from a window or floodlight falls on the image. Images may then appear washed
out and less vibrant.
In general, avoid or eliminate light sources directed at the screen.
Other considerations and tips that can help improve your installation:
• Keep the ambient temperature constant and below 35°C (95°F). Keep the
projector away from heating and/or air conditioning vents. Changes in
temperature may cause drifts in the projector circuitry, which may affect
performance.
• Keep the projector away from devices, which radiate electromagnetic energy
such as motors and transformers. Common sources of these include slide
projectors, speakers, power amplifiers, elevators, etc.
Choose the best screen size for the application. Since more magnification reduces
brightness, use a screen size appropriate for the venue but not larger than required.
Installing a large screen in a small room is similar to watching television at a close
range; too large a screen can overpower a room and interfere with the overall effect. A
good rule of thumb is to be no closer than 1.5 times the width of the screen.
Throw distance
Throw distance is the distance measured from your projector’s front feet to the screen.
This is an important calculation in any projector installation as it determines whether
or not you have enough room to install your projector with a desired screen size and if
your image will be of the right size for your screen.
You can quickly estimate the throw distance by taking the horizontal width of the
screen and multiplying it by the lens throw ratio. The result of this calculation tells
you roughly how far back the projector should be positioned from the screen in order
to project a focused image large enough to fill the screen. For example, using a 0.73:1
lens, throw distance would roughly be 0.73 x screen width.
IMPORTANT: Once you determine the type of lens and screen size you’re going
to use, calculate the precise throw distance using the formula or graphs located
in Appendix D. Due to lens manufacturing tolerances for lens focal length, actual
throw distance can vary
± 5% between lenses described as having the same throw
ratio.

Figure 2.1. Estimating Throw Distance
Vertical and horizontal position
The correct vertical and horizontal position of the projector in relation to the screen
depends on the lens type and the screen size. Ideally, the projector should be
positioned perpendicular to the screen. This way, the image will appear rectangular
instead of keystoned (trapezoidal).
The vertical position of the image can be offset – that is moved above or below the
optical axis (lens center) by adjusting the fully motorized lens mount with the keypad.
The amount of vertical offset available depends directly on the lens installed in the
projector and can be slightly limited if horizontal offset has been applied. Vertical
offset can also be expressed as the percent of half the image height OR the number of
pixels of shift from lens center. Refer to Figure 2.2 for some illustrated examples of
vertical offset.
Table 2.1 along with Figure 2.3 show the maximum vertical offset of a lens or
alternatively, how much of your projected image will appear above or below lens
center if the maximum vertical offset is applied using that lens.

The horizontal position of the image can be offset – that is moved to the left or right
of lens center, by adjusting the fully motorized lens mount through software. The
amount of horizontal offset available depends on the lens installed and if the image
has already been vertically offset. Horizontal offset can also be expressed as the
percent of half the image width – the number of pixels of shift to one side of lens
center. Refer to Figure 2.4 for some illustrated examples of horizontal offset.
See also Table 2.1 along with Figure 2.5 which shows the maximum horizontal offset
of a lens or alternatively, how much of your projected image will appear to one side of
lens center if the maximum horizontal offset is applied using that lens.

Mounting
There are several methods for mounting the projector. Depending on your chosen
installation, one method may be more suitable than another. In typical front and rear
screen installations the projector can be mounted to a secure and level surface, such as
a table or cart. Carts are useful when the projector has to be moved during a
presentation or from site to site. It is recommended you lock the wheels on a cart,
when it’s in position, to prevent someone from accidentally moving it during a
presentation.
CEILING MOUNT - The projector can also be inverted and suspended from the ceiling
using a specially designed ceiling mount fixture. This type of mounting is
recommended for fixed installations and for those that want the projector out of plain
view or have a limited amount of space for projector and audience. (Available 2005)
Use only the CHRISTIE approved ceiling mount kit designed for
your projector.
SPECIAL MOUNTING – The projector can be rotated (front-to-back) up to 360 degrees
and mounted without it affecting performance. However, the side-to-side tilt limit of
the projector must not exceed ±15 degrees. This tilt limit is required to ensure optimal
performance of the projector.
Adjusting projector height
You can modify the height of the projector to remedy a slightly unlevel mounting
surface by adjusting the two feet threaded into the bottom chassis. Turn each foot
clock-wise or counter-clockwise until the project is level on all sides.
Folded Optics
In rear screen applications where space behind the projector is limited, a mirror may
be used to fold the optical path. See Figure 2.6. The position of the projector and
mirror must be accurately set – if considering this type of installation call your dealer
for assistance.
Figure 2.6.

Section 2: Installation and Setup
2-12 User’s Manual
Sources connect to the Input Panel located at the back of the projector. See Figure 2.7.
The upper right corner (INPUT 1) typically accepts an RGB signal from an external
analog RGB source, or it can also be used for YPbPr signals or additional video
sources. Just beside these BNCs, the DVI-I connector (INPUT 2) accepts digital or
analog display signals from a computer. Connect analog composite video at INPUT 3
or S-video at INPUT 4 from devices such as VCRs, laser disc players or DVD players.
There are also several optional interfaces available for connecting other sources—
these interfaces slide into the remaining unused option slot, and can be done while the
projector is running.
Figure 2.7. Input Panel
NOTES: 1) See Section 6, Specifications for details regarding compatible inputs. 2)
Use high quality shielded cables only for all connections.
INPUT 1consists of 5 BNCs (connectors) for linking to a variety of sources. The
typical connection would be to an RGB source such as a PC, Mac, DEC, Sun, SGI and
others. This projector supports multiple sync types with RGB signals: sync-on-green,
composite sync, and separate H & V syncs.
NOTE: Depending on your source, you may need a custom adapter cable with BNC
connectors at the projector end and a different type of connector at the other (such as
a 15-pin "D" connector for some computer sources). Contact your dealer for details.
Connect the SYNC BNC input(s) first. Then connect the red, green and blue source
outputs to the RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses
sync-on-green, only the red, green, and blue connections are required. If the source
provides a composite sync output, connect it to the SYNC input labeled HOR/COMP. If
the source provides separate horizontal and vertical sync outputs, connect horizontal
sync to the SYNC input labeled HOR/COMP and connect vertical sync to SYNC input
labeled VERT. See Figure 2.8.

Figure 2.10.Connecting Composite or S-Video sources
Use the DVI-I connector at INPUT 2 to connect either analog or digital video devices
to the projector. When connecting devices that transmit an analog video signal such as
VCRs, laptops, and PCs use the DVI cable provided with the projector. Plug the
DVI-I (single link) connector end to the projector and the 15-pin VGA connector to
the device.
Use a cable with DVI-I connectors at both ends to connect devices that transmit
digital and analog video signals such as high-quality DVD players, satellite receiver
and digital cable TVs.
NOTE: 1) To ensure true digital output from devices that transmit digital signals,
connect to the DVI-I connector. 2) DVI loop through is not available unless you have
the optional DVI Input Module installed at INPUT 5 or INPUT 6.
Optional modules allow you to increase your total number of inputs and/or
accommodate different signal types, whether analog or digital. Install in the areas
labeled INPUT 5 or INPUT 6. Options include:
• RGB 500 Input Module
• RGB 400 Active Loop Thru Input Module
• RGB 400 Buffered Amplifier Input Module
• Composite/S-Video Input Module (not supported in v1.0 software)
• PC250 Analog Input Module

As an alternative to the projector’s keypad or remote, you may wish to communicate
with the projector using a PC or other controller. Such a device sends commands and
receives feedback via serial links (RS232 and RS422), Ethernet or GPIO
communications to the projector, all described below.
As desired, direct the projector’s IR remote keypad towards the display screen or the
projector’s IR sensors. Alternatively, connect a wired (tethered) version of the remote
to the 3.5mm RCA jack labeled as REMOTE on the projector’s input panel. Note that
response to a wired keypad must also be enabled in the Communications menu—see
3.6, Adjusting System Parameters and Advanced Controls for more information.
There are two types of serial ports available on the projector: RS232 and RS422. You
can connect a device with a serial interface, such as a computer to either of these
connectors (not both) and control the projector remotely by entering specific serial
communication commands.
Connecting RS-232
The two 9-pin DIN connectors labeled RS232 IN and RS232 OUT on the input panel
are dedicated to serial communication. Using the appropriate serial communication
cables (see Appendix C) connect the controlling source, such as a personal computer
to the RS232 IN connector. Then set the baud rate to match that of the computer.
Refer to Section 3 for details on changing the projector’s baud rate.
Figure 2.11. Connecting RS232
If you want to connect multiple projectors in a network with serial communication,
connect the controlling source to the RS232 IN connector of the first projector in the
network. Then take another serial communication cable and connect one end to the
RS232 OUT connector and the other end to the RS232 IN connector of the next
projector. Continue this pattern of connection with all projectors in the network. The
last projector in the network will only have a connection to the RS232 IN connector.

Connecting RS-422
If you wish to control the projector with a computer and or other controlling device
with RS-422 capability, connect a RS-422 serial communication cable between the
computer and the RS-422 port on the projector. RS-422 is better suited for serial
communication over long distances then is RS-232 communication.
Use the RS-422 port only if your device had RS-422 capability – always consult
the literature provided with your equipment before connecting. Connecting to the RS-
422 port with incompatible equipment could damage your projector.

Ethernet Communications
To add the projector to an existing Ethernet network with other equipment such as
controllers and other projectors, connect standard CAT5 Ethernet cable between your
Ethernet controller (or hub) and the Ethernet port on the side of the projector.
Upon connection to an Ethernet network, the projector’s factory default IP address of
0.0.0.0.0 will automatically enable the DHCP function (if available on the network) to
assign a new IP address that is valid and unique for that network. Or, if there is no
DHCP function available on the network (or if a specific static IP address for the
projector is preferred or required), you can set the address in the Ethernet Settings
menu or via an ASCII serial command.
