one to the projector via a serial command. The projector will respond to commands 
sent to this address after the next power-up, after which the IP address will remain in 
projector memory until you enter a new one, or until the DHCP checkbox is re-
enabled. 
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. 
NOTES: 1) A separate ”redundant” network requires double serial links—RS232 
and
 RS422—between all projectors. 2) Set each projector’s Broadcast Key to OFF. 
3) Keypads cannot broadcast when networks are separate—use controller(s) instead. 
4) Do not use a split network when downloading new projector software. 
By default, communications originating from one type of serial controller—RS232 
vs. RS422—stay on the corresponding network path rather than being broadcast to 
the other network. This separation is sometimes known as a split network and is 
indicated by a “Separate” setting for “Network Routing” in the Communications 
menu (see Figure 2.37). 
 
Figure 2.37. Keeping Networks Separate (default) 
Keeping networks separate maximizes the efficiency of data transmission. In 
addition, separate paths means that one path can be considered a redundant “back-
up”, available if a failed projector (or controller) prevents communication via the first 
path. With a split network, each projector receives and sends either type of message 
depending on which controller initiates the commands—should one path fail, the 
second “back-up” network path can be used. Only one network should be active at a 
given time, as determined by the controller type, i.e., whether it is RS232 or RS422. 
Note that the “Broadcast Key” option must be OFF. 
Two Different Serial “Splits” 
There are two different split serial network configurations possible (see Figure 2.38). 
Set up whichever option best suits your application needs: 
A. SPLIT NETWORK WITH ONE CONTROLLER – If you have a single controller and 
want a back-up serial link, connect one controller standard (e.g., RS232) to 
one physical end of the network and the other controller standard (e.g.,    Separating or Joining 

 Serial Networks

RS422) at the other physical end of the network. Make sure the “Separate” 
option is selected for “Network Routing” in the Communications menu. If a 
projector should then fail anywhere in the network, communication with the 
remaining projectors can be resumed in the opposite direction using the other 
standard. NOTE: This configuration requires that both standards be available 
from a single controller, or that you use an RS232/RS422 adapter. 
B. SPLIT NETWORK WITH TWO CONTROLLERS – If you have two controllers (one 
RS232 and one RS422) and want one to be a back-up, connect each controller 
to the appropriate port on the first projector in the network. Then connect 
projectors together using both RS232 and RS422 ports as shown. Make sure 
the “Separate” option is selected for “Network Routing” in the 
Communications menu. Now, if either controller fails, you can simply switch 
to the other controller and communicate via the other standard. 
Remember, for either configuration in 
Figure 2.38, make sure to segregate the 
networks from one another by selecting the 
“Separate” option for “Network Routing” in 
the Communications menu. 
NOTE: When connecting RS422 to a projector, use either of the identical rear ports 
(6-pin XLR) or the 9-pin “RS422 IN” port on the side input panel.

 IMPORTANT  
Whenever downloading new projector software to networks, use a 
single-route RS232 network only. DISCONNECT any redundant serial 
cabling and Select “Separate” for “Network Routing” in each projector.  
To relay messages to all ports—RS232, RS422, and 
Ethernet—regardless of the original source, set the 
“Network Routing” option in the Communications 
menu to “All Joined” for each projector. This 
configuration is useful if you have one type of 
controller available but must link projectors via the other type. For example, you may 
need to use both an RS422-compatible controller and an Ethernet-connected PC for   Communicating to 
 All Ports

working with a network of projectors linked via their RS232 in/out ports. In this case, 
select “All Joined” for “Network Routing” in the Communications menu so that all 
messages reach all ports throughout the network. 
 
Figure 2.39. Joining All Networks 
If desired, you can isolate your RS422 communications so that they are not relayed to 
any other network—select the “RS232 and Ethernet joined” option for “Network 
Routing” in the Communications menu. Messages from Ethernet will reach the 
RS232 network, and vice versa, but RS422 messages will not. 
 
Or, to isolate Ethernet select “RS232 and RS422 Joined”—all serial messages will be 
relayed to all serial ports, but Ethernet communications will not (and vice versa). 
To keep each communication link separate from the others, select “Separate”. 
It is helpful to define a unique 3-digit projector number to each projector connected 
in a serial network (for instance, 001, 002, 003, etc.). These numbers enable you to 
direct commands to a single projector rather than always broadcasting to the entire 
network. For complete information on how to assign and use projector numbers on a 
serial network, see 3.8, Adjusting System Parameters and Advanced Controls. 
 
 
 
Do not connect the ballast to AC unless the projection head and ballast are already 
connected to each other, otherwise the exposed live ends of the heavy ballast cables 
could be a serious hazard.

AC power levels vary from region to region throughout the world, with 400 VAC 
common in some countries (such as those in Europe and Asia), and 200 AC common 
elsewhere (such as in North America and Japan). To accommodate both possibilities, 
this ballast includes an internal Input Power Range Switch
 for toggling to the level of 
AC available at the installation site, i.e. either 200 or 400 VAC. The line cord plug 
must also match. 
From the factory, the ballast’s switch and line cord are both set for 200 VAC use. 
Used/rented ballasts shipped from other installation sites may be set to either, 
depending on where they were last used—check the status of the line cord plug and 
switch before attempting to connect to AC. See instructions below (Figure 2.40). 
 WARNING  
Qualified electrical technician required. 
1. A visual 
inspection of 
the plug will 
indicate 200 or 
400 VAC 
status. Modify 
as necessary for 
your site—as a 
delta load with 
safety ground, 
the plug has no 
neutral. 
2. Remove the 
ballast cover to 
access and read 
the Input Power 
Range Switch. 
3. Toggle the 
switch left for 
use with 200 
VAC supplies, 
or toggle right 
for 400 VAC 
supplies. 
4. Attach the 
ground lug to 
Earth Ground. 
5. Re-install the 
ballast cover. 
Connect all 4 ballast 
cables—two DC 
power cables, and 2 
communication/control cables—to the rear of the projector and to the lamp ballast.

When the ballast has been properly configured (see 2.8, Connecting the Ballast) and 
connected to the projection head, connect its integral line cord to AC. Then: 
Before powering 
up, set which size 
lamp is installed. 
This ensures that 
proper power is 
provided to the 
lamp upon 
ignition, 
preventing the 
risk of seriously 
overdriving a 
lamp. 
 
 
 WARNING  
Explosion hazard. Keep the projector OFF until you 
have defined which lamp type is installed. 
1. Press Menu. The Status Display at the rear of the projector will show a “Lamp 
Size” of 2000, 3000, 4500 or 6000 watts, depending on its last setting (factory 
default=6000). See Figure 2.41. 
2.  Enter either the Lamp Password (see Figure 2.41), or the Christie service 
password. NOTE: A password is required unless the “Enable Password” 
service option has been turned off. 
3. Use 
 to select which lamp is currently installed. 
4.  When the Status Display shows the correct lamp type, the projector and lamp 
can be turned on. Make sure the lamp type is also indicated on the lamp door 
label—use a small sticker from the front cover of this manual, or mark with a 
pen. 
Power-up the Roadie 25K system as described in 3.3, Power-up Procedure/  
Checklist, Steps 1 and 2. 
In the Lamp menu, set the “Cable Length (m)” slidebar to match the length of the 
high-voltage DC cables connected between your lamp ballast and projection head. 
This regulates the voltage drop that occurs over distance, and ensures that adequate 
voltage reaches the lamp. Particularly in projectors rented for temporary installations, 
this setting may have to be changed from its last use. Adjustment range is 2-30m 
(6½-100 ft.).

NOTE: By default 
from the 
manufacturer, this 
projector is optimized 
for brightness rather 
than wider color 
gamut or higher 
contrast ratio—i.e., 
neither a small-
diameter contrast 
ratio aperture nor the 
yellow notch filter is 
installed in the 
projector. These are 
options. 
Upon powering up the 
projector with a 
newly-
installed/replaced 
lamp, adjust lamp 
position to help ensure 
optimized operation as well as peak brightness at the screen—you do not need an 
image displayed yet. Once you have done this LampLOC
 adjustment, the lamp will 
be well-centered and distanced correctly from the remainder of the illumination 
system. It can be re-adjusted as needed at any time. 
For best results in most applications, use the “Do Auto” button. The motorized lamp 
adjustments will begin and, in conjunction with an internal light sensor, will take a 
minute or two to position the lamp for optimized brightness. If desired, you can 
operate the motors individually and use the “Intensity” reading at the top of the menu 
for feedback. 
NOTE: Lamp must be on and shutter open during LampLOC
 adjustment, however 
the projector does not need to be displaying an image. 
 
NOTE: Assumes a single projector is powered up in its final location.  
This initial optical alignment procedure is the foundation for optimizing your 
displays, ensuring that images reflected from the DMDs are parallel to and well-
centered with both the lens and screen. It should be completed before adjusting lens 
boresight. 
NOTE: Before you begin:

2. COARSE FOCUS: Do a quick preliminary focus and (if available) zoom adjustment 
with the primary lens only (see 3.14, Working with the Lenses). Do not worry 
about consistency across the image at this point, just center focus. 
3. 
CENTER THE IMAGE IN THE LENS: Holding a piece of paper at the lens surface, 
adjust offsets as necessary until the image on the paper is centered within the lens 
perimeter. A full white field works best for this. 
4. 
RE-CHECK SIDE-TO-SIDE LEVELING: 
With a good test pattern on screen, 
double-check projector leveling (see 
2.3, Projector Position & Leveling) 
so that the top edge
 of the image is 
parallel to the top edge of the screen. 
See right. 
 
 
NOTES:1) Projector must 
be installed and powered 
up in its final location. 
Install the anamorphic 
lens if it will be used at 
the site. 2) You will need 
a 3/16” allen wrench. 3) 
Boresight may need slight 
adjustment after installing 
a new lens. 
To ensure proper offset 
for your site and 
consistently good focus in 
all areas of the screen, a 
primary lens must be 
installed and its lens 
mount precisely adjusted 
in relation to internal 
optics as described below. 
If desired, an anamorphic lens can then be added to widen images for “scope” 
displays. Once adjusted, boresight should remain stable until the lens is replaced. 
Refer to lens mount components illustrated in Figure 2.44 for these adjustments. 
NOTE: Project an image using the primary lens only
. The optional anamorphic lens, 
if present, can be mounted but swung aside. 
Prior to boresight adjustment, offset the image as required so that the image is square 
on screen but offset is minimal
. For best results, try to minimize offsets by “aiming” 
the projector lens at the center of the image. Refer back to 2.3, Projector Position 
and Mounting for offset ranges and method of adjustment.

1. Adjust focus at the 
far left center edge 
of the image 
(Figure 2.45). If 
possible, reduce 
image size for 
easier image 
analysis. 
2.  If the image 
appears well-
focused on the left 
edge but not on the 
right, then the 
boresight currently differs from one side to the other—i.e., the right side of the 
image is well-focused either in front of
 or behind the screen surface rather than on 
it. To determine where the right side is focusing:

3.  Adjust the horizontal boresight bolt 
(Figure 2.47) as necessary to direct or 
“aim” the lens toward the side of the 
image which focused too close to the 
lens. When both sides appear equally 
blurry, re-focus on the left side of the 
screen.  
4.  Adjust horizontal offset to re-center the 
image on the screen. 
5.  Repeat Steps 4 and 5 until both sides of 
the are well-focused. 
6.  Adjust the “hold” screw to lock in 
place, and check boresight again. 
7.  When the left/right 
boresighting is complete, 
focus the image at the 
top edge of the screen 
(Figure 2.48).  
If the bottom remains 
blurry while the top edge 
is focused, refer back to 
Step 2 but use a paper at 
the bottom of the screen 
to determine whether the 
bottom of the image is 
focused in front of
 the 
screen or behind
 the screen. If the bottom is well-focused, skip to Step 11. 
8.  Adjust the vertical boresight bolt (Figure 
2.49) using one allen key to hold the bottom 
hex screw and another to turn the adjustment 
bolt above it. Adjust as necessary to direct or 
“aim” the lens toward the edge of the image 
which focused too close to the lens. When 
both top and bottom appear equally blurry, re-
focus at the top of the screen. 
9.  Adjust vertical offset to re-center the image 
on the screen. 
10.  Repeat steps 8 and 9 until the top and 
bottom of screen are both well-focused.  
11. 
REFOCUS: Although all sides of the image 
should now be in focus, the center of the 
image will be slightly blurry at this point. 
Refocus at center of image. The goal is good focus at center and on all sides. 
12.  Adjust the “hold” screw to lock in place, and check boresight again.
