Lens Focus Adjustment for Fixed Lenses
This section describes best practices for lens focus adjustment of the 0.64:1 WUXGA lens 
(PN: 002-120444-02) and the 0.75:1 (PN: 002-120415-01). The lenses have focus and field curvature 
correction to sharpen the projected image. Failure to properly adjust lens focus results in an image that is not 
uniformly focused and contains geometric distortion.
1. Loosen the main locking screw and the focusing screw.
2. Adjust the focusing screw for best focus in the image center.
3. Loosen the field curvature locking screw and adjust the field curvature focusing ring to sharpen the image 
corners. Refer to the image below as an aid to gage the specific preset for your screen size.
4. Finally the focus screw should be tweaked for best overall screen focus. 
5. Although it is not necessary, you may want to retighten the main locking screw. NOTE: Use a maximum of 
4in.-lbs to tighten the main locking screw.

2.2.3 Calculating Throw Distance, Position and Mount Projector
Throw distance is the distance measured from your projector to the screen. This calculation determines if there 
is enough room to install your projector with a desired screen size and if the image will be of the right size for 
your screen. To estimate the throw distance take the horizontal width of the screen and multiply it by the lens 
throw ratio. The result determines approximately the distance the projector should be positioned from the 
screen to project a focused image large enough to fill the screen. For example, using a 1.2:1-1.6:1 zoom lens 
set at its widest (1.2:1) throw ratio, throw distance would roughly be 1.2 x screen width.
IMPORTANT: Use the lens and screen size to calculate the precise throw distance. Due to lens manufacturing 
tolerances for lens focal length, actual throw distance can vary 
±2% between lenses with the same nominal 
throw ratio.
Table 2.6  Lens Types, Offsets and Throw Distances 
NOTES: 
1) 
Offsets are subject to ±7% centering tolerance. 
2) Image size outside the specified width range may result in reduced image quality.
3) Throw distance is measured from the marked exit pupil position on the lens (see Figure 2-5) to the screen. 
Throw ratio is defined as:
4) 100% offset is defined as having all pixels shifted beyond the axis.
5) Offsets are measured from optical lens centre, which may not coincide with mechanical centre % offset is 
defined as:

Projector Vertical and Horizontal Position
The projection lens and the screen type determine the vertical and horizontal position of your projector in 
relation to the screen. Ideally, you should position the projector perpendicular to the screen to make the image 
appear rectangular instead of keystoned (trapezoidal). You can offset vertical position of the image (move it 
above or below the optical axis) by adjusting the lens mount. The type of projection lens you install determines 
the amount of available vertical offset. Vertical offset can be expressed as the percent of half the image height 
or the number of pixels of shift from lens center. 
NOTES: 
1) 
Offsets are subject to ±7% centering tolerance.
2) % offset is defined as:  
The horizontal position of the image can also be offset (moved to the left or right of optical center) by adjusting 
the lens mount. The amount of horizontal offset available depends on the lens installed and if the image has 
already been vertically offset. Horizontal offset can be expressed as the percent of half the image width or the 
number of pixels of shift to one side of lens center. % Offset# of pixels of offset

Section 2: Installation and Setup
Mounting the Projector
NOTICE: Use only the CHRISTIE approved projector mounts designed for your projector. Refer to the 
installation instructions and safety guidelines provided with in the kit.
There are several methods for mounting the projector. In typical front and rear screen installations the projector 
can be mounted to a secure and level surface. The projector can be mounted in any orientation without 
affecting performance. 
2.3 Connecting Sources
All source connections are made to the input panel of the Electronics Module. Each input is labeled for easy 
identification. Using the correct cable(s), connect your source. An interconnection label is available for 
reference on the light module. Sources are connected to the Input Panel located at the top of the EM. The Input 
Panel has slots for 1 image processor board and up to 4 input cards, and comes standard with 2 slots populated. 
The input cards are hot swappable; they can be plugged in and out while the projector is running. The image 
processor should only be replaced when the projector is OFF or when it is in STANDBY mode.
The video card that is installed in your projector determines the type of video source you can use. These video 
cards are supported:
• High-Definition Multimedia Interface/Twin HDMI (High-Definition Multimedia Interface) 
• Analog BNC 
• Dual SD/HD-SDI (Serial Digital Interface)
• Dual Link DVI
•Video Decoder
These cards slide into any of the available option slots. One or more of the option slots may be used with any 
combination of option cards, including multiples of the same card type. One input is active on any card at a 
single time, except the Dual HDMI and Dual SD/HDSDI cards, which support up to 2 active signals on 1 card. 
NOTE: Use only high-quality shielded cables for all connections.
LEDS
LEDs are located on the faceplate of each input card and indicate the following:
• Power ON - Green
• Signal Valid - Green
• Signal Invalid - OFF
DVI Digital Video
Use the DVI-I connector to connect either analog or digital video devices to the projector. Use a cable with 
DVI-I connectors at both ends to connect devices that transmit digital and analog video signals such as satellite 
receivers and digital cable TVs. 
NOTE: For true digital output from devices that transmit digital signals, 
connect to the DVI-I connector.

Dual Link Digital Video Input (DVI) Input Card
This card accepts a maximum 330MHz DVI-D or 165MHz HDMI signal via the DVI-I connector without 
High-Bandwidth Digital Content Protection (HDCP) and analog video signals over the DVI-I or 15-pin VGA 
connector. The module can simultaneously support a digital signal on the DVI input and an analog signal on 
the VGA port; however, it does not support 2 analog signals at the same time. There are 4 LEDs on the module 
faceplate. PWR indicates power is applied and the card is initialized, and the other 3 LEDs on the right-side of 
the corresponding connectors indicate that a valid signal has been detected.
Twin HDMI Input Card
This card accepts 1 or 2 HDMI inputs, and can route one or both inputs to the card’s outputs without High-
Bandwidth Digital Content Protection (HDCP). Any input from any card can be looped out of this card. The 
output label ‘1-OUT’ loops out the main image being displayed on the projector. The output labelled ‘2-OUT’ 
loops out the image displayed in the picture in picture (PIP). Any input from any optional input card can be 
looped out of this card. There are five LEDs on the module faceplate. The PWR on the left side indicates 
power is applied, and that the card is initialized. The LEDs to the right side of the corresponding connectors 
indicate that a valid signal is detected. In the case of the outputs, the LED indicates a signal is currently being 
looped out. 
Analog BNC Input Card
This card accepts several types of sync modes. In 5-wire sync mode all 5 BNC connectors are used. If H and V 
connectors are swapped, this card will still operate normally. An analog graphic source such as a VGA from a 
PC can be connected. The card can operate in 4-wire sync mode, which accommodates 4-wire RGBC sources. 
The composite sync cable can be connected to either the H/C BNC or the V BNC. The card supports 3-wire 
RGB or YPBPr sync modes, sometimes called sync-on-Green (SOG). In this mode the H/C and V connectors 
are not used. The sync is connected to the Green/Y BNC connector. This card offers no loop out capability. 
There are 2 LED’s on the module faceplate. PWR indicates power has been applied and the card is initialized, 
signal indicates a valid signal has been detected.

Dual SD/HD - SDI Input Card
This card accepts both standard-definition (SD) and high-definition (HD) serial-digital-interface (SDI) signals 
from one of two standard-definition (SD) or high-definition (HD) SDI sources. Both single-link HD and dual-
link HD signals are accepted. The card has two SD/HD-SDI outputs, each of which is “loop through” for its 
respective input. There are three LEDs on the module faceplate. PWR indicates power has been applied and the 
card is initialized, and the two signal LEDs indicate a valid signal has been detected on the respective input.
 
Video Decoder Input Card
This card accepts and decodes standard definition (SD) video. This includes CVBS (composite video), S-
Video, and component sources. This card supports as many as six video signals, four of them on BNC 
connectors and two on four-pin mini-DIN connectors. Each mini-DIN connector accepts one S-Video signal. 
The first BNC accepts composite video (only), while the remaining three BNCs can be grouped to allow one of 
the following combinations:
• 3 CVBS sources on 4, 5 & 6
• 1 CVBS source, 1 S-Video source: Luma (Y) connected to 4 (Sy) and Chroma (C) connected to 6 (Sc)
• 1 YPbPr source: component signal on 4(Pr), 5(Y) & 6(Pb)
The video decoder input card has 8 LED indicators. The PWR LED indicates that the module is installed 
properly, and has been successfully configured. The YPbPr LED indicates that a valid component signal has 
been detected on inputs 4, 5, and 6 (Component input grouping must also be selected in the projector’s menu - 
see Section 3 Operation. The remaining LEDs are each associated with one of the inputs and indicate a valid 
signal has been detected on that input.

with the cable, connect the cable to the remote and to the connector labeled 
REMOTE on the Electronics Module 
input panel. Check Wired Keypad Enabled in the Communications menu.
As an alternative to the projector keypad or remote, communicate with the projector using a PC or other 
controller. Commands and feedback are sent to the projectors Electronics Module using Ethernet or serial links 
(RS232 and RS422). 
NOTE: Do not connect to the Projector Head Module (PHM).
2.6 Projector Network Setup for External Communication
This section outlines a several ways to set up a Mirage WU-L projector network for external communication.
IMPORTANT: To complete the projector network setup you will also need to connect the projectors together for 
arrayLOC communication and functions. See ArrayLOC Network on page 3-53.
2.6.1 Ethernet (Recommended)
In the Ethernet network the controller communicates with each projector separately.
To add a projector to an Ethernet network:
1. Connect a standard CAT5 Ethernet cable between the controller (or Ethernet hub) and the Ethernet port on 
the projector Electronic Module. 
2. Set the IP address in Configuration > Communications > Ethernet Settings. See Ethernet Settings on 
page 3-34.
3. Set Configuration > Communications > Network Routing to Separate. See Network Routing on 
page 3-33.

Mirage WU-L User Manual2-13020-100774-01 Rev. 2 (4-2012)
2.6.2 Mixed Network
In the mixed network the controller can communicate with the first projector and the command can be relayed 
to each serially connected projector. This configuration is useful if you are using a non-RS232 controller with 
the RS232 linking available between these projectors. The example shows both an RS422-compatible 
controller and an Ethernet-connected PC for working with a network of projectors linked using their RS232 in/
out ports.
• Connect the controller to one projector:
• A standard CAT5 Ethernet cable between the controller (or Ethernet hub) and the Ethernet port on the 
Electronic Module
• An RS-422 serial cable between the PC and the RS422 IN (pictured). 
• Connect a serial cable between the RS232 OUT connector of the first projector
 Electronics Module and the 
RS232 IN connector of the next projector Electronics Module. Connect the remaining projectors. RS232 
communication cables must be good quality and no more than 25 feet in length.
• If you connected the controller, using an Ethernet cable, set the IP address in Configuration > 
Communications > Ethernet Settings. See Ethernet Settings on page 3-34.
• Set the serial options in Configuration > Communications. See Communications on page 3-32.
•Set Configuration > Communications > Network Routing. See Network Routing on page 3-33.
• To relay commands to all projectors set Network Routing to All Join.
• To isolate just RS422 communications, select RS232 and Ethernet Joined. Only projector #3 will 
respond to the RS422 controller. 
• To isolate just Ethernet communications, select RS232 and RS422 Joined—only projector #1 will 
respond using Ethernet.
