RPMX/CX50/CX60/CX67 User’s Manual 1-1
Section 1: Introduction
1.2 Components
How the projector works
The projector operates based on DLP technology by Texas Instruments. An
external source provides the necessary XGA input signals accepted by the
projector. An internal 120W UHP lamp generates light, which then travels
through a rotating color wheel alternately passing red, green and blue light to the
single 0.7" imaging panel (also called a digital micromirror device or DMD).
Reflected light from the DMD then passes through the short throw projection
lens and displays on the external display screen.
NOTE: Refer to Section 3, for a brief description the projector’s main modules.
Ensure you have received the following components with your projector or
display cube:

DVI Digital Video Signals '
Connect Analog VGA signals to the 15-pin HD D-sub connector on the second
input interface. Figure 2.2.
Figure 2.2. Analog VGA Connector
The second input interface is dedicated to digital video input signals conforming
to the DVI (Digital Visual Interface) standard.
To connect an incoming digital video signal to the projector, connect the cable
running from the source to the DVI input connector - the DVI output adjacent to
the DVI input connector remains empty. If you want to loop the source through
to another display device, connect a cable from the DVI output connector (that
was empty) to a DVI input connector on the digital display. See Figure 2.3.
To loop the DVI signal through a series of display devices continue looping
connection in this manner – your last device will have an empty DVI output
connector. See Figure 2.4. All projectors will display the same as the first
projector, no matter what type of input signal is present for other projectors, even
internal test patterns.
NOTES: 1) When looping a DVI input signal, all projectors will display the same
data from that one source.

2.2 Serial Port
Connections
If using a computer '
There are two, 9-pin DIN connectors on the input panel dedicated to serial
communication. These connectors allow you to connect your projector to an
external controlling device with a serial interface, such as a personal computer,
for the purpose of communicating without having to use the keypad.
SINGLE PROJECTOR
Connection: Using the appropriate serial communication cable (see Appendix
D), connect the controlling device (PC) to the serial port labeled RS-232 IN.
(Figure 2.9.)
Figure 2.9. Single Projector Connection and Communication Schematic
MULTIPLE PROJECTORS
Connection: When connecting multiple projectors in a network, use an
appropriate serial communication cable (Appendix D) and connect the controlling
device (PC) to the RS-232 IN connector of the first projector in the network.
With a second serial communication cable, connect the one end to the RS-232
OUT connector of the first projector and the other end to the RS-232 IN of the
next projector. Continue this pattern of connection with all projectors (Figure
2.10.). The last projector in the network will only have a connection to the RS-
232 IN connector. Then set the baud rate of all projectors to match that of the
controlling device. Refer to Communication on page 3-19 for details on setting
baud rate.
NOTE: 1) In Figure 2.10 and Figure 2.11, the controlling device can only send
commands to the projector. It cannot query or receive any feedback from the
projector. If feedback from the projector is required, an RS-232 switche r must
be used and connected as shown in Figure 2.12. Call a Christie sales
representative for more information.

2.3 Power Connection
There are two AC receptacles on the EM. To plug in a single projector, plug the
power cord into the top AC receptacle (labeled INLET). Then plug the 3-pronged
end of the power cord into a grounded AC outlet.
If you want to connect multiple projectors (up to a maximum of 4), connect a
second power cord to the AC receptacle (labeled OUTLET) on the left side of the
first projector and the other end to the AC receptacle (INLET) of the next
projector. Continue connecting power cords in this manner until you reach the
last (or 4
th
) projector in the chain. The last projector will have an empty AC
receptacle OUTLET. See Figure 2.13.
Input voltages must be capable of 100-240 VAC. Use an appropriately rated
AC power cord with the projector. The power cord supplied is approved for
North American use only. See Section 5, Specifications for all power
requirements.
WARNING
Do not attempt operation if the AC supply and cord
are not within the specified voltage and power range.

Section 3
Operation
This section provides a general description of the projector’s main components. It
also provides details on the projector’s software menu system.
3.1 Projector
Overview
Projection Head Module '
(PHM)
The modular design of the projector allows the user to access and service specific
components of the projector, such as the lamp, quickly and easily without having
to disassemble the entire projector.
Figure 3.1. The Projector (shown in lens horizontal configuration)
The PHM is the largest module of the projector. It contains all the main optical
components of the projector such as the short throw projection lens, color wheel,
DMD and lamp.
In the RPMX projector, the PHM is shipped in a 0 degree (lens horizontal)
configuration. With a quick changeover of mounting brackets, the module can be
flipped to a 90-degree (lens vertical) position for rear screen projection
applications using an optical fold mirror. (In CX50/CX60/CX67 products the
projector is already in the 90-degree position.)
Located on the top of the PHM is a small red switch that allows you to switch the
lamp power from 100W to 120W. It is recommended that you choose the 100W
setting when you are performing setup procedures for the first time.
RPMX/CX50/CX60/CX67 User’s Manual 3-1
Section 3: Operation
Electrical Module (EM)
'
The EM is the main control unit of the projector. It is mounted independently
from the PHM to the mounting tray. It is the module where all source
connections are made and where the main power switch is located.
The EM contains the majority of PCB’s, such as the Control PCB, BNC Input
PCB, Video Input PCB and Control RS-232C PCB. In general, these boards are
responsible for the video processing and communication requirements of the
projector. It also houses the IR sensor PCB and the Power PCB.
Located on the input side of the EM are 3 LEDs. These LEDs will illuminate in
patterns, which represent the status of the projector and/or any error conditions
that may be present. Refer to Table 3.1. for the status of the LEDs during normal
operation and at the end of this section for system error codes.

6-Axis Adjuster '
You can correct the geometry of a displayed image by adjusting the uniquely
designed 6-axis adjustment mechanism. The PHM can be mounted to this
mechanism in a lens horizontal (0 degree) or a lens vertical (90 degree)
orientation. The mechanism, which is manually adjusted, can be adjusted to
correct any geometric misalignment between the projector and the screen.
Typically, this mechanism only requires adjustment during the initial setup of the
projector. Adjustments can be locked in place to avoid tampering and the need
for re-adjustment.
The 6-axis adjuster and EM are mounted to a welded frame called the mounting
tray. The purpose of this tray is to keep the modules together and makes the
installation process easy. It can be installed on any sturdy, flat surface as long as
all four mounting points are used to secure it in place.
Refer to the separate Installation Guide provided in the User’s Kit for installation
instructions and how to adjust the 6-axis adjuster.

Section 3: Operation
3.2 Using the Keypad
The projector is controlled by an IR remote keypad that is supplied in the User’s
Kit. It is operated by 2 AA batteries and provides wireless control of the
projector from up to 100 feet away.
Keep in mind the batteries will require replacement over time. If the projector is
not responding to keypad entries and there isn’t an obstruction of the IR sensor, it
may indicate the batteries require replacement.
IR Remote Keypad '
The IR remote keypad controls the projector by
way of wireless communications from a batterypowered infrared (IR) transmitter. Use the IR
remote keypad the same way you would use a
remote keypad supplied with a TV or VCR.
When making key presses, point the keypad
directly at the center of the screen.
Keep in mind the following when using the
keypad:

much as possible leading to a distorted image. If you are using HDTV,
selecting the default preset will give you the same result as if choosing
Anamorphic.

“Tiled” Resize Presets
A number of preset options do not appear in the list, until the array is defined in
the Tiling Setup window found in the Configurations menu. Options include
RPMX/CX50/CX60/CX67 User’s Manual 3-9
Section 3: Operation
Tiling Full Screen, Tiling Full Width, Tiling Full Height and Tiling
Anamorphic. These options are essentially the same as the ones described above
except they expand across displays in the defined array. See 3.7 Using Multiple
Projectors later in this sect i on.

“CUSTOM” RESIZE PRESETS
Custom appears in the list of available resize presets as an unnumbered
option. It occurs only when the values for Size and Vert Stretch (in the Size
and Position menu) are altered.
The values you choose for Custom will remain in the projector’s memory for
the current source, until they are modified.
NOTES: 1) When you are using your projector for the first time, Custom will
not appear in the list of Resize Presets or “Tiled” presets. This option only
appears when the values for Size and Vert Stretch are modified.
Size
Adjust Size when you want to change the image width and height
simultaneously, while maintaining the current aspect ratio of data from the
incoming signal. As you adjust the slidebar for Size, you will notice the value for
Vert Stretch changes accordingly and image proportion is maintained.
Vert Stretch
Adjust Vert Stretch (short for “Vertical Stretch”) when you want to adjust the
height of the image while maintaining the width of the image. By adjusting this
option, you will change the aspect ratio of the image. NOTE: Adjusting this
option does not change the value for Size.
Pixel Tracking
Use this option to adjust the frequency of the pixel sampling clock, indicated by
the number of pixels per line, so that all pixels generated by a particular source
are sampled. Proper pixel tracking ensures that the image quality – whether good
or not – is consistent across the screen, that aspect ratio is correct and that pixel
phase can be optimized.
Pixel tracking is adjusted most effectively using a good test pattern, such as a
smooth gray consisting of a clear pattern of tiny black and white dots, or a similar
“one pixel on, one pixel off” graphic image, such as the Windows shutdown
screen. Steady flickering or several soft vertical stripes or bands across the entire
image indicates poor pixel tracking. Adjust the slidebar until the stripes broaden

to the point where one large stripe fills the image. Again, the image may still
exhibit some noise.
NOTE: 1) By default, the projector will sample at the correct frequency for most
sources. 2) Not available for video sources. 3)

Pixel phase
Use this option to adjust the phase of the pixel sampling clock relative to the
incoming signal. It is used primarily for adjusting RGB inputs.
Adjust pixel phase when the image (usually from an RGB source) shows
shimmer or “noise”. Pixel phase adjustment is done most effectively using a
proper test pattern, such as a smooth gray consisting of a clear pattern of tiny
black and white dots, or a similar graphic image, such as the Windows shutdown
screen. Adjust this option until the image is stable and each dot is clearly defined.
Using the numbers on the slidebar as a guide, you will notice that you can
actually stabilize the image at more than one point—i.e., you may find that the
image appearance at "11" is identical to the image appearance at "38", thus you
can select either setting.
NOTE: 1) Adjust pixel phase after pixel tracking is properly set. 2) Not
applicable for video sources. 3)
