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 towards the display screen or the 
projector’s IR sensors. Alternatively, connect a wired (tethered) version of the remote 
to the RCA jack labeled 
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 2.14. 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. 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. 
CONNECTING TO A PC: If you are connecting the Ethernet port directly to a PC (rather 
than a network or hub), make sure to use a crossover Ethernet cable. Keep in mind 
that an Ethernet link cannot be used for downloading a software upgrade to the 
projector—use RS232. 
 
Figure 2.16. 
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.  
						

							Section 2: Installation and Setup 
 
Christie DS+60/DW30/Matrix 3000 User’s Manual     2-17  
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. 
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 2.17. 
 
Figure 2.17. 
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 2.18.   Connecting Multiple 

 Projectors  
						

							Section 2: Installation and Setup 
2-18   Christie DS+60/DW30/Matrix 3000 User’s Manual  
 
Figure 2.18. 
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. 
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 2.19. 
 
Figure 2.19. 
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 2.20  
						

							Section 2: Installation and Setup 
 
Christie DS+60/DW30/Matrix 3000 User’s Manual     2-19  
 
Figure 2.20. 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. 
NOTES: Only the port and IP address of the projector can be changed. The subnet 
mask is fixed (255.255.255.0). 
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. 
By default, communications originating from one type of serial controller—RS232 vs. 
RS422 vs. Ethernet—stay on the corresponding network path. This separation is 
indicated by a “Separate” setting 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 2.20).

To isolate just RS422 communications, select “RS232 and Ethernet Joined”. In Figure 
2.21. 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 (General Purpose Input Output) 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. 
 
Plug the line cord to the AC receptacle located on the right hand side of the projector 
and the 3-pronged end into a grounded AC outlet (Figure 2.22). The input voltage to 
the projector must be capable of 100 – 240 VAC. (See also Section 6 – Specifications 
for complete details on all power requirements.)  
Each projector is provided with the North American and European rated line cords. 
Make sure you are using the appropriately rated line cord for your area.  
Always power down the projector before unplugging the AC line cord – Once you 
power down, wait 2 minutes to allow the main exhaust fan to turn off and for the 
lamps to cool 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.

(3) The AC receptacle is located on the right side of the projector (opposite side of 
lamp doors). Use this outlet to plug in an appropriately rated line cord. See 2.6 Power 
Connection for details.  
The input voltage to the projector must be capable of 100 – 240 VAC. See also 
Section 6 – Specifications for complete details on all power requirements. 
(4) Located on the bottom of the projector are 3 adjustable feet. You can raise or 
lower these feet to ensure the projector is level on all sides and the image displays 
rectangular without any keystone. See Projector Position and Mounting (Section 2) 
for instructions on adjusting these feet.  
(5) The projector is built with a motorized lens mount that allows for easy lens control 
and adjustment. This includes such functions as adjusting vertical and horizontal 
offsets, zoom and focus. The lens mount can be fitted with any one of the available 
optional lenses – see Section 6 - Specifications.  
• Zoom and Focus – There are two internal lens motors that allow for quick 
motorized adjustment of zoom and focus. Adjust zoom to fit the displayed 
image on the screen and adjust focus to improve the clarity of the image. 
NOTE: You can manually override zoom and focus adjustments set with the 
remote. Turn the outer ring on the projection lens to adjust focus and the 
inner ring to adjust zoom.  
• Lens Offset – Vertical and horizontal offset is performed on the lens mount 
through the use of DC motors.  
• Shutter – Standard on all models the shutter allows you to turn the screen 
absolutely black when in the “on” state. 
• Optical Aperture –Enables adjustment of light output and contrast ratio. 
NOTES: 1) The projection lens is shipped separately from the projector. 2) Use the 
lens cap when transporting the projector to avoid scratching and damaging the lens, 
which could affect your displayed image. 
(8) The 
LENS RELEASE button, located just below the projection lens, allows for a 
quick “tool-free” lens changeover. For instructions on how to use this button during 
lens replacement refer to Section 4 – 4.5 Replacing the Projection Lens.  
(10) All source connections are made to the input panel located at the back of the 
projector. Connect RGB or YPbPr sources to 
INPUT 1, analog or digital display signals 
to 
INPUT 2, composite video to INPUT 3, and S-video to INPUT 4. INPUT 5 is where you 
would install any of the available optional input modules.  
There is no status display on the input panel. The only status display is part of the 
built-in keypad located on top of the projector. 
 
(9) There are numerous air vents located around the projector. It is important these 
vents remain unobstructed. Allowing adequate airflow through the projector will 
prevent it from overheating.  
NOTE: 
 Stand clear of the rear exhaust air path during operation. In the unlikely 
event of a lamp explosion, glass particles can be blown out of these vents.

(6) & (11) The two IR sensors located on the projector receive transmissions from the 
IR remote from up to 100 feet away. It is important to keep the transmission path to 
these sensors unobstructed for uninterrupted communications with the projector. The 
front IR sensor is located next to the projector’s nameplate and the rear IR sensor is 
located just below the input panel. 
(13) & (14) Located on the right hand side of the projector are two lamp doors that are 
labeled as Lamp #1 or Lamp #2. Each door is fitted with an amber window that makes 
it easy to identify which lamp because it will glow. NOTE: It is important to always 
check the status of the lamp before opening the lamp door. Opening a lamp door 
while the lamp is still on will cause power to be cut to that lamp. 
(15) Use the following slot to install a standard Kensington lock to keep your 
projector secure in some installations. 
 
 
 Laser radiation is emitted from the laser diode in the remote. Do not look 
directly into the beam of the remote.
 
 
The projector is typically controlled using one of the following keypads: 
• Built-in Keypad located on the top, right edge of the projector  
• IR Remote for wired or wireless control up to 100 feet away (includes 
cable for use as a wired remote) 
While each of the keypads provides complete control of the projector, they differ 
slightly in their arrangement of keys and in what functions can be accessed directly 
with a key press rather than requiring use of the menu system. You may find one 
keypad more convenient than another for your specific installation and application.  
NOTE: The IR remote has a single IR protocol. It can be converted to a wired IR 
remote by connecting the cable provided with the projector to the mini stereo 
connector labeled 
REMOTE on the input panel.  
To control the projector when 
signals from an IR remote 
cannot reach the projector, 
use the projector’s built-in 
keypad. Two nearby status 
windows provide feedback 
indicating current status and 
activities of the projector. 
Because the built-in keypad has fewer keys than the remote control, certain projector 
functions are accessible only through the menu system rather than via a direct key. 
Refer to the key descriptions provided for the IR remote.

The IR remote controls the projector by way of wireless communications from a 
battery-powered infrared (IR) transmitter. Use the IR remote the same way you would 
use a remote control supplied with a TV or VCR. When making key presses, direct the 
keypad either toward the screen or toward the front or rear of the projector. One of the 
two IR sensors on the projector will detect the signals and relay the commands for 
internal processing.
