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.

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.

NOTES: 1) If for some reason the projector fails to recognize a signal as an RGB 
signal, specify this Color Space option within the Image Settings menu. See 3.5 
Adjusting the Image. 2) To connect YPbPr signals–such as from DVDs or analog HDTV 
sources–to 
INPUT 1, use the red, green and blue BNCs as described in YPbPr Signals 
(below). 
 
Connect a YPbPr signal (component video) to INPUT 1 or INPUT 2 as shown in Figure 
2.9. 
NOTES: 1) If, for some reason, the projector fails to recognize a YPbPr signal, 
specify this Color Space option within the Image Settings menu. See 3.5, Adjusting 
the Image. 2) Do not connect digital
 component signals (known as YCbCr) to INPUT 
1
. Install an appropriate optional module in INPUT 5 or INPUT 6 for this.

INPUT 3 and INPUT 4 provide simultaneous connection of both a composite video 
source (
INPUT 3) and an S-Video source (INPUT 4). See Figure 2.10.  
 
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 
• Serial Digital Input Module 
• DVI Input Module 
• Dual SD/HD-SDI Module 
(available 2005)

 User’s Manual     2-15. 
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. 
 
Figure 2.13. Connecting RS422 
 
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.  Ethernet Communications
