 INSTALLATION AND SETUP 
 
Roadie 25K User’s Manual 2-25 
Connect a YPbPr signal (component 
video) to 
INPUT 1 or INPUT 2 as shown 
in Figure 2.27. 
NOTES: 1) If, for some reason, the 
projector fails to recognize a YPbPr 
signal, specify this Color Space option 
within the Image Settings menu. See 
3.7, Adjusting the Image. 2) Do not 
connect digital
 component signals 
(known as YCbCr) to 
INPUT 1 or INPUT 
2
. Use the appropriate optional digital 
interface installed in 
INPUT 5 or 6 only....

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. 
Connect as shown at right.

Not possible. Composite and S-Video connect to INPUT 3 and INPUT 4 only. 
Optional input modules allow you to increase your total number of inputs and/or 
accommodate different signal types, whether analog or digital. Install in the areas 
labeled 
INPUT 6 or (if available) INPUT 5. These interfaces include: 
• RGB 500 Input Module 
• RGB 400 Active Loop Thru Input Module 
• RGB 400 Buffered Amplifier Input Module 
• Composite/S-Video Input Module...

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...

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...

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...

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.

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...

Figure 2.33. Typical RS422 Network 
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...
