Mixed Serial Network (RS-232 and RS-422)
RS-422 serial communication is better over long distances than RS-232 communication. Use the RS-422 port 
only if your device has RS-422 capability. Always read the equipment literature before connecting. 
NOTICE: Connecting to the RS-422 port with incompatible equipment, including the wrong type of serial cable, 
can damage the projector.
In the RS-422 network the controller can communicate with the first projector and the command can be 
relayed to each serially connected projector. 
• Connect the controller to one projector using RS-422 serial cable between the PC and the RS-422 IN port on 
the Electronic Module.
• Connect an RS-232 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 
using RS232 cables. RS232 communication cables must be good quality and no more than 25 feet in length.
• Set the serial options in Configuration > Communications. See Communications on page 3-32.
•Set Configuration > Communications > Network Routing to one RS232 and RS422 Joined. See Network 
Routing on page 3-33.

2.7 Projector Network Setup for ArrayLOC Communication
See the Integration Guide for detailed information about arrayLOC setup. 
2.8 Setting up the Image
2.8.1 Adjusting the Projection Lens
NOTICE: Lock lens adjustments to prevent unnecessary tampering.
Loosen the adjustment locks on the lens barrel before making adjustments.
2.8.2 Adjusting Image Geometry and Optical Alignment
Only perform image alignment once the projector is fully assembled and powered up in its final location. Basic 
image alignment ensures the image reflected from the DMD is parallel to and well-centered with the lens and 
screen. This initial optical alignment is the foundation for optimizing images on the screen, and must be 
completed before final boresight adjustments. Before beginning, ensure that the projector is properly 
positioned relative to the screen.
Basic Optical Alignment Procedure
1.Display a test pattern: Appropriate for analyzing image focus and geometry, such as the “framing” test 
pattern showing the cross-hair centered across the image. Press the Test key on the remote keypad. 
2.Coarse focus: Do a quick preliminary focus and (if available) zoom adjustment with the primary lens. Do 
not worry about consistency across the image at this point, just center focus. It is good practice to have the 
zoom adjustment collar and the focus adjustment collar in the center of its range.
3.Center the image in the lens: Holding a piece of paper at the lens surface, adjust offsets as necessary until 
the image is centered within the lens perimeter. A full white field works best for this.
4.If necessary, center the image on the screen: If the projector is mounted off-center to the screen axis, 
then offset the lens as much as required. Aim the projector over slightly towards the center of the screen, 
but use caution, as too much tilt will cause excessive keystone distortion. Lens offset will not. 
5.Re-check side-to-side leveling: With the framing pattern on screen, double-check projector leveling so the 
top edge of the image is parallel to the top edge of the screen.
6.Throw distance: Ensure that the projector is positioned in the throw distance range for the lens in use.

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 contact Christie Customer Support for assistance.
2.8.3 Boresight Alignment (Advanced)
1. Display the Boresight Test Pattern by pressing the Te s t key on the remote keypad, then use the Left arrow 
key to cycle to Boresight, see Figure 2-7.
2. Focus the image on the cross-hair pattern at the image center. Evaluate the focus on cross-hair image I and 
II. If all three images are in focus, no further action is required. If boresight is required see step 3.

Section 2: Installation and Setup
3. If boresight is required, see Figure 2-8 to understand how the adjustment screws on the lens mount affect 
the corresponding cross-hairs on the test pattern.
4. Use a 5mm Allen key to loosen the three locking setscrews on the lens mount, see Figure 2-9. 
NOTE:The setscrews must be backed out several turns, so that they do not contact the inner lens mount 
plate.
5. Fine tune the focus of cross-hair pattern I by adjusting the appropriate capscrew, see Figure 2-9. Adjust 
until the cross-hair image is in focus with minimal flare.
6. Adjust cross-hair pattern II, by adjusting the appropriate capscrew, see Figure 2-9. Adjust until the cross-
hair image is in focus with minimal flare.
7. Adjust cross-hair pattern III, by adjusting the 
appropriate capscrew, see Figure 2-9. Adjust until the 
cross-hair image is in focus with minimal flare.
8. Repeat steps 5, 6 and 7 as required until all three cross-
hair patterns are in equal sharp focus. If the boresight is 
acceptable, see Step 11. If the boresight does not appear 
to be converging to an acceptable level of image quality 
or if the lens will not focus over the correct range of 
throw distances, then the boresight requires coarse 
adjustment, see step 9.
9. The original factory boresight can be recovered 
approximately by positioning the 3 setscrews, see 
Figure 2-9. Position the setscrews flush with the front face of the lens mount plate and in contact with the 
inner lens mount plate, see Figure 2-10. This may require adjusting both setscrews and capscrews.
10. If further action is required. Repeat step 2.

11. Lock the set screws and re-check the boresight quality. Tighten the setscrews enough to ensure they will 
not shift.
12. When the image is focused, lock adjustments in place by tightening the adjustments until just tight.
2.9 Adjust software to Optimize Image
NOTES: 1) See Section 3 for details on accessing and adjusting individual settings. 2) Unless otherwise 
indicated, instructions apply to all projector models in stand-alone or multi-projector configurations.

Section 2: Installation and Setup
2.10 System Integration - GPIO Connector
The General Purpose Input-Output (GPIO) connector located on the Mirage WU-L projector input panel is 
used to enable control of stereo function. 
GPIO and External Devices
If you want to use GPIO to interface external I/O devices to the Mirage WU-L projector, you will need to have 
a custom adapter made. Seven GPIO pins on the 9-pin D-Sub GPIO connector are configured through RS232 
commands. The other two pins are reserved for ground and power. See GPIO Pins for pin identification. The 
cable required for connecting the external device to the projector GPIO connector, whether a standard serial 
cable or a custom one, must be compatible with the external device. 
The GPIO connector can be configured to automate any number of events using the serial command code GIO. 
Each pin is defined as either an input or output depending on the desired outcome. In general, configure the pin 
as an input if you want the projector to respond to something the device does and as an output if you want the 
external device to respond to an action taken by the projector. For example, configure the pin as an output if 
you want the lighting in a room to automatically dim when the projector is powered ON. By using the GIO 
command, you can also set the state of each pin as high or low. By default, the state of each pin is high. The 
voltage applied to pins in the high state is + 3.3V. See  (GIO) General Purpose Input/Output, on page D-29.
2.11 Projection Lenses, Lens Mount and Other Features
Using the lens cap when transporting the lens avoids scratching and 
damaging the lens.
The Mirage WU-L projector includes a lens mount that allows lens control and adjustment: vertical and 
horizontal offsets, zoom and focus. The lens mount can be fitted with any one of the available optional lenses – 
see Section 7 Specifications.
•Zoom and Focus – Adjust zoom to fit the displayed image on the screen and adjust focus to improve the 
clarity of the image.
•Lens Offset – The lens mount allows vertical and horizontal offset of the displayed image.
•Shutter – Standard on all models, the shutter allows you to turn the screen absolutely black when in the 
“Closed” state. A WHITE shutter state allows you to view menus and images if RGB brightness is set to 0.

2.12 Cleaning the Lens
Check periodically. A small amount of dust or dirt on the lens has minimal effect on image quality. To avoid 
the risk of scratching the lens, clean only if absolutely necessary.
Dust:
1. Brush most of the dust from the lens with a camel-hair brush or blow dust away with a dust-free blower.
2. Fold a microfibre cloth smooth and gently wipe remaining dust particles from the lens. Wipe evenly with 
the smooth portion of the cloth that has no folds or creases. DO NOT apply pressure with your fingers - use 
the tension in the folded cloth itself to collect dust.
3. If significant dust is still bound to the surface, dampen a clean microfibre cloth with coated optics cleaning 
solution (damp, not dripping). Wipe gently until clean.
Fingerprints, smudges, or oil:
1. Brush away most of the dust with a camel-hair brush and/or blow away using a dust-free blower.
2. Roll a lens tissue around a swab and soak it in coated optics cleaning solution. The tissue should be damp, 
but not dripping.
3. Gently wipe the surface using a figure-8 motion. Repeat this motion until the blemish is removed.

3 Operation
 See Safety Warnings and Guidelines in 5 Maintenance.
This section describes the controls and switches used for basic projector operation once it is properly installed, 
aligned and configured by a Christie accredited service technician. You can access projector controls and 
settings with the IR remote, or with a laptop using the web interface. This chapter focuses on the use of the IR 
remote, and the projector menus. For information about accessing the same functionality through the web 
interface, see Appendix B: Web User Interface.
3.1 Using the IR Remote
 Laser radiation is emitted from the laser diode in the remote. Do not look
directly into the beam of the laser. 
The standard IR remote can be used as a wired or wireless control. Under optimal conditions, the wireless 
keypad can communicate with a projector over a 100 foot distance. In wireless mode, the standard IR remote 
communicates with the projector with a battery-powered infrared (IR) transmitter. 
Use the standard IR remote the same way you would use a remote control supplied with a TV or DVD player. 
When pressing a function key, direct the standard IR remote toward the projector’s front IR sensor. The IR 
sensor on the projector will detect the signal and relay the commands for internal processing. A laser pointer is 
built into the standard IR remote.  
Keep these guidelines in mind:
• Press keys one-at-a-time; there are no simultaneous key combinations required. 
•NOTE: To use Power, Shutter, and OSD functions, press the appropriate button and then press the 
UP arrow 
to switch ON or the 
DOWN arrow to switch OFF. You can also press-and-hold the appropriate button for 2 
seconds, or press it twice quickly. 
• Arrow keys are held down for continuous adjustment/movement in the related key direction. 
•NOTE: In serial networks, pause briefly between adjustments to make sure that more distant projectors can 
“keep up” with the commands. If you press a key while the projector is still responding to the previous 
action, such as during power-up, the second key press may not take effect. 
•See 3.1.1 IR Remote, on page 3-2 for the description of those keys provided for the standard IR remote 
keypad.
