Sources connect to the Input Panel located at the back of the projector. See Figure 2.6. 
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 2.6. Input Panel 
NOTES: 1) See Section 6 – Specifications for details regarding compatible inputs. 2) 
Use high quality shielded cables only for all connections.  
INPUT 1 consists of five 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 2.7.

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 
2.8. 
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 2.9.  
 
Figure 2.9.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. 
NOTES: 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 
• PC250 Analog Input Module 
• Serial Digital Input Module 
• DVI Input Module (standard on Mirage HD models) 
• Dual SD/HD-SDI Module (standard on Christie HD models)

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 nine-pin DIN connectors labeled RS232 IN and RS232 OUT on the input 
panel are dedicated to serial communication (see Figure 2.10). 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 2.10. Connecting RS232 
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 (see Figure 2.11). 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. 
Regardless of how it is assigned, once a projector has a valid and unique address it 
will respond to commands sent to this address. To determine the projector’s current IP 
address, consult the Status or Communications menus. 
Refer to Section 3 for further information about setting up and using a projector 
connected via Ethernet. 
Log on to www.christiedigital.com for detailed information on ChristieNET™. 
 
RS-232 NETWORK: 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. See Figure 2.12.  Ethernet Communications f

Figure 2.12. RS232 Network 
MIXED NETWORK: To control multiple projectors with a computer/controller having an 
RS422 interface, first set them all to the same baud rate as your RS422 controller. 
NOTE: You must enable this combination of RS422 and RS232 in the 
Communications menu. Set the “Network Routing” option to “RS232 and RS422 
Joined”. See Section 3 for details. 
Then chain the projectors together by connecting an 
RS232 port of the first projector 
(already connected to the computer/controller through the 
RS422 port) to an RS232 
port on the next projector in the chain. Continue connecting projectors in this manner 
until you’ve reached the last projector in the chain, so that only the last projector has 
one unused 
RS232 port. See Figure 2.13. 
 
Figure 2.13. Mixed Network 
Note that communication parameters such as baud rate must be set to match the 
particular controlling device before connecting as a network—refer to the 
documentation that came with your controlling device in order to determine the proper 
baud rate. See 3.6, Adjusting System Parameters and Advanced Controls if you need 
help changing the projector baud rate. In addition, set the Network Routing to “RS232 
and RS422 Joined” if you want to reach all projectors. 
NOTES: 1) To avoid damage, connect only properly wired serial communication 
cables. See Appendix C for details. 2) It is recommended that each RS232 
communication cable be no more than 25 feet in length. Use high quality cables.  
						

							Section 2: Installation and Setup  
2-18      020-100001-01 Rev. 01 (04/07) 
ETHERNET NETWORK SETUP: To add one or more projectors to an Ethernet network, 
use standard CAT5 cable to connect each projector’s Ethernet port to a hub belonging 
to the network. A controller or PC must also be connected to the hub. See Figure 2.14. 
 
Figure 2.14. Ethernet Network 
SETTING THE PROJECTOR’S IP ADDRESS: Upon connection to most Ethernet 
networks, each projector’s factory default IP address of 0.0.0.0 triggers the network’s 
DHCP (Dynamic Host Configuration Protocol) server function to automatically assign 
an IP address that is valid and unique for use on that network. Depending on the 
network, this DHCP-assigned IP address usually remains stable for a single session, 
but may change with subsequent power-ups and logins. On some networks, the 
address will remain stable from session to session. In all cases, the projector’s IP 
address and port appear in the Status menu as well as the Ethernet Settings submenu. 
See Figure 2.15. 
 
Figure 2.15. Setting the Projector’s IP Address 
Note that if a projector’s IP address is anything other than 0.0.0.0  (shown as 
000.000.000.000 in the Ethernet Settings menu) upon connection to an Ethernet 
network, or if DHCP is not available on the network, the automatic DHCP server 
function for supplying a valid and unique IP address to the projector is disabled. 
Instead, a specific and static IP address must be defined in projector memory—enter 
the new address in the Ethernet Settings submenu, or send to the projector via a serial 
command. The IP address will be in effect until it is changed again, or until the DHCP 
checkbox is re-enabled for use with a DHCP server on the network. 
CHANGING THE PORT#: On some Ethernet networks, firewall restrictions may require 
that the port number of the projector be changed from its default of 3002. If so, enter a 
new port number in the Ethernet Settings menu or include the new port# in an XIP 
serial command sent to the projector. It is highly recommended not to use a port# 
below 1000, as these ports are typically reserved for and used by common IP 
applications.

020-100001-01 Rev. 01 (04/07) 2-19. 
SUBNET MASK AND DEFAULT GATEWAY: The Subnet Mask and Default Gateway are 
automatically assigned when DHCP is enabled. If a static IP is being used, it must be 
assigned before the subnet mask. The Default Gateway is an optional router device 
used to send and receive data outside the subnet. 
ArtNet INTERFACE SETTINGS:  Refer to Section 3.6 – Adjusting System Parameters 
and Advanced Control, System Configuration – Communication for additional 
information about ArtNet settings.  
By default, communications originating from one type of serial controller—RS232 vs. 
RS422 vs. Ethernet—stay on the corresponding network path. A “Separate” setting 
indicates this separation for “Network Routing” in the Communications menu. If you 
are using an RS422 controller, for example, it will communicate only with the 
projector to which it is connected unless you change this setting to either “RS232 and 
RS422 Joined” or “All Joined”. 
To relay all messages to all ports—RS232, RS422, and Ethernet—set the “Network 
Routing” option in the Communications menu for each projector to “All Joined”. This 
configuration is useful if you are using a non-RS232 controller with the RS232 linking 
available between these projectors. For example, you may want to use both an RS422-
compatible controller and an Ethernet-connected PC for working with a network of 
projectors linked via their RS232 in/out ports. 
 
Figure 2.16. Joining All Networks 
To isolate just RS422 communications, select “RS232 and Ethernet Joined”. In Figure 
2.16, only projector #3 will respond to the RS422 controller. To isolate just Ethernet 
communications, select “RS232 and RS422 Joined”—only projector #1 will respond 
via Ethernet. 
The GPIO connector on the input panel can be used to provide a method of interfacing 
a wide range of external I/O devices to the projector.  
Refer to Appendix E: System Integration for complete details on pin configuration 
and how to program the various pins on the connector.

 The North American rated line cord is provided with each projector. Ensure 
that you are using a line cord, socket and power plug that meets the 
appropriate local rating standards.
 
Plug the line cord to the AC receptacle located at the back of the projector, below the 
input panel, and the three-pronged end into a grounded AC outlet. Ensure the socket 
outlet is installed near the equipment and is easily accessible. 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 ensure an appropriately line cord 
rated for the region of use is used.  
Always power down the projector before unplugging the AC line cord. Wait 5-10 
minutes for the main exhaust fan to turn off and for the lamp to cool sufficiently 
before unplugging the projector.  
 WARNINGS  
Do not attempt operation if the AC supply and cord are not 
within the specified voltage and power range. 
Wait for the cooling fans to turn off before unplugging the 
projector.

This section explains how to effectively operate the projector once it has been 
installed. It is recommended that you read this section and familiarize yourself with 
the components and the available menu options before you begin using your projector 
for the first time. 
 
 
  
The built-in keypad is located at the back of the projector, beside the input panel. Use 
it similarly to the IR remote to control the projector. A status LED display is also 
included on this keypad for monitoring projector status. 
The AC receptacle is located at the back of the projector just below the input panel. 
Use this outlet to plug in an appropriately rated line cord. Refer to Section 6 – 
Specifications for details.  
Located on the underside of the projector are two fully adjustable feet. Raise or lower 
these feet when positioning the projector to ensure it is level on all sides so the 
displayed image will appear rectangular without any keystone.  
NOTE: The third foot, located at the rear of the projector (underside) is not 
adjustable.   
Refer to Section 2 - Projector Position and Mounting for instructions on how to 
adjust the projector’s feet.
