INPUT 3 and INPUT 4 provide 
simultaneous connection of both a 
composite video source (
INPUT 3and 
an S-Video source (
INPUT 4). See 
Figure 2.28. 
NOTE: Unlike previous Christie 
projectors, composite video and S-
Video cannot connect to any other 
locations on the input panel.

Christie’s Dual SD/HD-SDI module is standard with this projector, and factory-
installed in the first option slot (labeled 
INPUT 5). Its loop-through capability enables 
incoming serial digital data (HD format) to be tiled across multiple screens, creating 
vast “mega resolution” displays. Alternatively, the multiple outputs can be 
overlapped for extra-bright displays, or simply distributed to additional projectors for 
multiple screens of the same image. 
The module accepts one or two independent standard- or high-definition serial digital 
inputs, decodes them for processing in the main electronics of the projector, and 
outputs 10-bit YCbCr 4:2:2 video. Either input can be set as the active primary or 
secondary part of a Picture-in-Picture display, and either input can be looped through 
to one (or both) of the module’s BNC outputs. 
NOTE: Selection of these inputs is described in 3.2, Using the Keypads. 
Connect a compatible SMPTE 292M or SMPTE 259M-C source(s) to one or both of 
the inputs located on the left side of the module. The module will automatically 
detect the standard at each input and configure itself accordingly for correct 
termination of the signal. The module also detects and supports dual link 292M for 
SMPTE 372M video standards.   Com

Roadie 25K User’s Manual 
 
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 (2 types), Ethernet or GPIO communications, 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 either the 3-pin XLR connector rear (standard) or the 3.5mm phono jack on the 
side of the projector, depending on which type of cable you are using with this 
remote. Note that response to a wired keypad must also be enabled in the 
Communications menu—see 3.8, Adjusting System Parameters and Advanced 
Controls for more information. 
 
 
Note that if both wired remotes are connected, communications via the side input 
have priority over communications via the rear.

RS232 Serial Communications 
From most computers, connect a 
standard RS232 serial 
communication cable between the 
computer and the projector serial 
port labeled 
RS232 IN—this 9-pin 
connector is located on the input 
panel on the side of the projector. 
Then set the projector’s baud rate to 
match that of the computer. 
Changing the baud rate is done in 
the projector’s Communications 
submenu. See 3.8, Adjusting System 
Parameters and Advanced Controls. 
 
 
 
 
 
 
 
 
 
RS422 Serial Communications 
Some computers can provide RS422 serial communications (often through a plug-in 
adapter or external converter) rather than the more common RS232 standard. RS422 
communication has differential “transmits-and-receives” and is generally better 
suited for long distances than is RS232 communication. Note that RS422 is not 
compatible with RS232—connecting a RS232-compatible PC to RS422 can damage 
the equipment at either end. Consult the documentation provided with your PC if 
your are unsure.   Other Controllers

Figure 2.30. Connecting Serial Communications via RS422 
There are three RS422 ports on the projector—two are 6-pin XLR ports (rear of 
projector) and the remaining is a 9-pin D-connector (side of projector). Use any of 
these ports for communications to and from an RS422-compatible controller, and/or 
as in-and-out ports for networking multiple projectors together on a serial network 
(note there is no 9-pin “out” port). 
NOTES: 1) Do not use the rear ports for downloading main software upgrades to the 
projector—use the 9-pin side port only. 2) Upon power-up of an RS422 network, wait 
until all projectors are initialized before sending further commands. Commands sent 
during initializing will be lost. 
 CAUTION  
Do not use an RS422 port unless you are using 
equipment with RS422 capability. The voltage levels of 
this signal can damage incompatible equipment.

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. 
NOTES: 1) Ethernet crossover
 cable 
required if connecting directly to a PC 
only. 2) Downloading new software to the 
projector via Ethernet is not supported. 
Upon connection to an Ethernet network, 
the projector’s factory default IP address 
of 0.0.0.0 will automatically enable the 
DHCP server function (if a DHCP server 
is available on the network)—i.e., the 
projector will obtain from the DHCP 
server a new IP address that is valid and 
unique for that network. Or, if there is no 
DHCP server present (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 after the next power-up. To 
determine the projector’s current IP 
address, consult the Status or 
Communications menus. 
Refer to 3.8, Adjusting System Parameters 
and Advanced Controls for further 
information about setting up and using a 
projector connected via Ethernet. 
The GPIO Port 
The General Purpose In-Out (GPIO) port enables integration of the projector within 
an established control system so that other devices connected via GPIO can operate 
in tandem with projector, or vice versa. ASCII commands sent via standard serial 
ports can be stored in projector memory, where they can then trigger a sequence of 
events in response to incoming or outgoing signals at the GPIO port, depending on 
your programming of the GPIO pins. For example, you can automatically dim the 
room lighting when the projector is turned on, or automatically turn the projector off 
when the lights are raised. 
For more information, refer to Appendix E.

Roadie 25K User’s Manual 
You may wish to link two or more projectors together so that commands and 
communications to and from a controller are relayed between projectors. Choose a 
hardware configuration that best suits your desired communication method. 
 
RS232 NETWORK: To control multiple projectors with a computer/controller having 
an RS232 interface, first set all projectors to the same baud rate as the controller, then 
chain the projectors together by connecting the 
RS232 OUT connector of the first 
projector (already connected to the computer/controller) to the 
RS232 IN connector of 
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 an 
unused 
RS232 OUT port. See Figure 2.32. 
 
Figure 2.32. Typical RS232 Network 
RS422 NETWORK: To control multiple projectors with a computer/controller having 
an RS422 interface, first set them all to the same baud rate as the controller, then 
chain the projectors together by connecting an 
RS422 port of the first projector (already 
connected to the computer/controller) to an 
RS422 port on the next projector in the chain. 
Use any of the three RS422 ports available on the projector—two are at the rear (6-pin 
XLRs), and one is on the side input panel (9-pin D-connector). Continue connecting 
projectors in this manner until you’ve reached the last projector in the chain, so that only 
the last projector has two unused 
RS422 ports. See Figure 2.33.

You can also connect by RS232 or RS422 (see Figure 2.34), in which case either 
type of serial communication must also reach the other type of port. You must enable 
this joining of network ports in the Communications menu—set the “Network 
Routing” option to “RS232 and RS422 Joined”. Serial messages will reach all serial 
ports.

Roadie 25K User’s Manual 
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 3.8, Adjusting System Parameters and Advanced Controls if you 
need help changing the projector baud rate. 
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 
2.35. 
 
Figure 2.35. Typical 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 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 the current session, but 
may change with subsequent power-ups and logins. On some networks, the address 
will even 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. 
 
Figure 2.36. Setting the Projector’s IP Address 
Note that if a networked projector’s IP address is anything other than the default of 
0.0.0.0 (shown as 000.000.000.000 in the Ethernet Settings menu), or if a DHCP 
server is not available, the automatic DHCP server function for supplying a valid and 
unique IP address is disabled. Instead, you must define a specific and static IP 
address by entering the new address in the Ethernet Settings submenu, or by sending   Ethernet Networks
