band represents the last band of the grayscale pattern, which should be 100% 
white (or the current color, if a certain color is enabled). Do not adjust too far. 
5) It may be advantageous to go back and check the black band—adjust the 
blacklevel slidebar if necessary. NOTE: Readjusting blacklevels at this point 
affects the gain; only re-adjust if absolutely necessary. Adjust until both bands 
are just optimized. 
6) Repeat Steps 2-5 with the other two remaining primary colors. When each 
primary color shows one optimized black band and white (or colored) band, the 
input levels for this source are correctly set. Upon exiting the Input Levels menu, 
the Peak Detector checkbox will clear.

GAMMA TABLE: This control applies a default video or graphics gamma table or 
“curve” to your images, controlling the intensity of midlevel colors while 
maintaining maximum contrast, brightness 
and color performance. As shown at right, 
the graphics curve is a simple power curve 
while the video curve has a linear segment 
near black to compensate for increased 
blacklevels typical of video signals. 
Although the projector automatically 
applies either the graphic or video curve 
according to what type of incoming signal is detected, in some cases you may wish to 
override this default and use graphics gamma for a video source or video gamma for 
a graphics source. Alternatively, if neither default is ideal, you may prefer to apply a 
user-defined custom gamma curve that has been created externally, named, and

 software applications). If any special user curves have been 
installed, their names will appear in the Gamma Table pull-down list. 
Keep in mind that any Gamma Table choice sets the related Gamma value (shown in 
the Image Settings menu) to a 2.5 default, where it can be fine-tuned as desired. 
Different values (1-3) here indicate that the original gamma table has been adjusted 
with either the Gamma slidebar or direct key. 
SELECT COLOR ADJUSTMENT: In “Select Color 
Adjustment”, choose an overall color performance for all 
images. The “Max Drives” factory default simply drives all 3 
colors at their maximum level so that they are fully on and 
cannot be changed. The two other pre-defined color 
adjustment choices—SD Video and HD Video—apply a color 
gamut optimized for video sources (standard or high-
definition). Alternatively, you can specify a color 
temperature, which enables the nearby Color Temperature 
slidebar and applies its current setting (default = 6500K). If none of the pre-defined 
“Select Color Adjustment” options or color temperatures suit your application, select 
one of four color gamuts previously defined by a user (User 1, 2, 3, 4). A “User” 
option applies a customized color performance in which the user has precisely set the 
hue and intensity of each color component in the Color Adjustment by X/Y or Color 
Saturation submenus, and is most often needed with multiple-projector applications. 
Select the color adjustment producing the best color accuracy for your application 
and installation. 
To configure a “User” color adjustment (gamut), use either the Color Adjustment by 
X/Y or Color Saturation submenu. 
NOTES: 1) “Color Temperature” defaults to 6500K until changed. All four “User” 
options default to SD Video unless they have been redefined by the user. 2) Factory-
defined color primaries, which ensure consistent color gamut from projector-to-
projector, can be altered in the Service menu only. If you suspect alteration, the 
factory settings can be recovered with selection of Reset to Factory Defaults? in the 
Service menu (password-protected). 
COLOR TEMPERATURE — Adjust to apply a specific color temperature to all displays. 
Color temperatures are expressed in degrees Kelvin (3200-9300K), and utilize 
different combinations of the projector’s original native color primaries to produce a 
“coloration” or cast (reddish or bluish) in images—the lower the temperature, the 
more reddish the cast; the higher the temperature, the more bluish the cast. Note that 
slidebar is enabled only if you have a source connected and have selected “Color 
Temperature” in the adjacent “Select Color Adjustment” pull-down list in the 
Advanced Image Settings menu.

Simulation 3D — SUBMENU OF ADVANCED IMAGE SETTINGS 
Use the options in the Simulation 3D 
menu to make timing adjustments for 
realistic simulation environments. 
FRAME DELAY MONITOR — This 
slidebar monitors the latency between 
input and output. For best results, the 
bar width and value should remain 
fairly constant, indicating that timing 
of input and output frames is locked; 
the Frame Delay Monitor value should stay within 5-10 lines or so of the Frame 
Delay setting. If a frame is lost or “dropped”, the bar will move suddenly and the 
values will change, indicating that the frame input is no longer equal to the output. 
FRAME DELAY — Set the number of lines delayed between the input signal and its 
appearance on screen, keeping in mind that projector processing always adds one 
frame of delay to the frame delay setting. For applications such as simulation, where 
the feeling of “real time” image response is a priority, a minimum setting is usually 
preferable. For projectors capable of stereographic 3D applications where alternating 
left-right frames must be synchronized with the corresponding L/R shutters in 3D 
glasses, a total frame delay setting of two (or multiple of two) may be more useful. If 
set too high or low, frame locking will not be possible—most sources require 
approximately 50 lines of delay to ensure frame locking. 
Check how the menu appears: 
RESERVED — No function. 
3D STEREO SYNC LOCKING — Not available in this projector. May be shown as 
“Reserved”.  
3D STEREO SYNC SELECT — Not available in this projector. May be shown as 
“Reserved”. 
3D STEREO SYNC DELAY — Not available in this projector. May be shown as 
“Reserved”. 
FRAME LOCK ENABLE—When checked, the output image frame rate is locked to the 
input signal frame rate when possible. When the images are not locked, the input and 
the output will run as close to the same rate as possible, but frames may occasionally 
be duplicated or dropped. 
WARP LATENCY — Requires optional ChristieTWIST module. See ChristieTWIST 
User’s Manual provided with the module.

MOTION FILTER — 
This control is most useful for smoothing out 
moving images from interlaced sources. In most cases the proper 
Motion Filter setting is automatically determined according to the type 
of incoming source signal. However, if your source is noisy and/or 
inconsistent you may wish to “force” a setting to ensure stable

processing for this source—if desired, override the default “Auto” setting by 
selecting the appropriate motion filter: 
1) AUTO: The projector will automatically use the correct motion filter according to 
the incoming signal. 
2) STILL: For static images with no motion, such as graphics from a CD. 
3) MOTION: For video images that did not originate from film, or for moving 
computer-generated images. 
4) FILM: For video images that originated from film. This will optimize image 
quality and stability. 
FILM MODE THRESHOLD —  This setting determines how sensitively the projector can 
detect if an incoming video signal originated from film or not. 
DETAIL THRESHOLD — Use “Detail Threshold” to define at what frequency level the 
“Detail” control will begin to magnify high frequencies, which adds details back into 
the image. Raise the threshold to ignore more of these high frequencies, and lower 
the threshold to magnify more of these frequencies. A setting of “0”, for example, 
means no noise will be ignored and all will be magnified. An ideal detail threshold is 
one in which high frequencies that are causing objectionable noise are not magnified 
when using “Detail”, but frequencies which can help sharpen an overly-soft image 
are magnified when using “Detail”. 
 
Use the Configuration menu 
to define general operating 
parameters and 
communications with other 
projectors and equipment, and 
to access other advanced 
processing and image 
adjustments affecting overall 
performance. In addition, the 
Configuration menu provides 
access to diagnostics, 
calibration tools and the 
Service submenu (password-

— SUBMENU 
Use the options in this submenu 
to adjust the appearance, content 
and/or location of on-screen 
menus and messages. 
LARGE MENU FONT — Enter a 
checkmark to enlarge menus and 
their text. You may have to 
adjust “Menu Location” to 
accommodate the increased 
menu area. 
MENU LOCATION — Use the pull down list to choose a pre-defined default or 
customized location for the display of all on-screen menus.  
To create a custom menu location quickly, choose a preset that is closest to the 
desired location. Then adjust the slidebars of Horizontal Shift and Vertical Shift to 
move the menu to the desired location. To prevent cropping of larger menus, avoid 
locations too close to a corner or edge. 
HORIZONTAL AND VERTICAL SHIFT — Shift your menus as desired, creating a 
customized menu location. 
DISPLAY CHANNEL LIST — Enter a checkmark if you want to see a scrollable channel 
list whenever you press 
Chan from your presentation. Channels marked with a list 
icon 
 in the Channel Setup menu will then appear here. The Display Channel List 
option also enables on-screen feedback when using the Input key. If you prefer to hide 
the channel list and input dialog box while switching channels and sources during a 
presentation, clear the checkbox. 
NOTE: The Channel List and input dialog box cannot be hidden during use of the 
menus. 
DISPLAY SLIDEBARS — Enter a checkmark to superimpose a small slidebar over the 
current image whenever an adjustable parameter is selected directly with a key such

in menus. 
DISPLAY ERROR MESSAGES — Choose how you want to be notified of errors 
detected in either the incoming signal or projector.
 Select “Screen” or “All” (default) 
to see brief on-screen messages. This is particularly recommended during setup or 
testing of the projector. Or select “RS232” to receive messages via RS232 (or 
RS422) serial communication only. To hide error message displays, such as during 
shows and presentations, select “Off” or “RS232”. 
SPLASH SCREEN SETUP — Use the Splash Screen to choose when you would like to 
display a special introductory splash screen image, such as your company logo, 
graphic or message. 
• Always Off = A splash screen never appears 
• Always On = A splash screen is always on behind the current display 
image, similar to wallpaper. 
• Startup Only – The splash screen logo appears at projector startup only. 
• Startup And No Signal – A splash screen appears at startup only if there is 
no source signal. 
To replace the default “Christie logo” splash screen (or other) with one of your own, 
use KoRE Librarian
 to download the desired .bmp to the projector. This will 
overwrite the current splash screen content in projector memory. 
Settings in the Communications 
submenu define and control how 
single or multiple projectors are 
can link with each other and with 
a controlling device. 
Baud Rates 
The baud rate setting determines 
the speed of communication to 
and from the projector on the 
RS232 or RS422 links. The 
maximum rate for either standard 
is 115200. Set the baud rate to 
match that of your controlling device, such as your PC. If you are unsure about what 
baud rate to choose, refer to the documentation for the controlling device. In an 
existing network of projectors, if you discover that a projector has a different baud 
rate, make sure to use the pull-down list and select the correct baud rate using the 
Enter key—do not just scroll this control with  or  keys. Serial 
communication is always 8 data bits, no parity. 
Projector 
Enter a three-digit number (such as 001”) to assign or change a number to the 
projector currently in use. If the current projector already has a number assigned, that 
number will appear here (for example, “004” in Figure 3.18, above). Numerical 
identity for projectors enables you to communicate with a single projector within a 
multiple-projector application (see also 
Pr o j key in 3.2, Using the Keypads). If you 
make a mistake in assigning or changing the projector number, press 
Ex i t to cancel.

Network Routing 
Not applicable for stand-alone projectors or simple networks with only one type of 
controller and linking. 
 
SEPARATE: Select “Separate” (factory default) to keep RS232, RS422 and Ethernet 
messages on their respective paths instead of being broadcast to other types of ports. 
This is useful when you have a network in which each projector is connected via both
 
its RS232 and RS422 serial ports (Figure 3.19
A)—at each projector, serial 
communications will stay on the path of origin only, as determined by the type of 
controller. If a projector or path ever fails, you can use the other path. 
In Figure 3.19
A, failure to keep the networks separate would likely cause 
communication errors. In Figure 3.19
B, where there is only one link between any 
two projectors (and the controller), make sure to join the networks. 
If you have a simple serial network with only one type of linking—RS232 or 
RS422—the type of network routing does not matter. 
 
Figure 3.19. Using the “Network Routing” Option 
RS232 AND RS422 JOINED: Messages to and from any serial port will also be relayed 
to all other serial ports. Use when there is only one physical link between any two 
projectors, but which might be RS232 or RS422. 
RS232 AND ETHERNET JOINED: Messages to and from the RS232 ports will also be 
relayed to the Ethernet port, and vice versa. Any RS422 communications will be 
isolated. 
ALL JOINED: All messages reach all ports, regardless of type.

Ethernet Settings (SUBMENU) 
NOTES: 1) Not used for stand-alone projectors. 2) Recommended for network 
administrators only. 
DHCP: Enable this checkbox if you want a DHCP server to automatically change the 
projector’s default IP address (0.0.0.0) to one that is valid and unique for use on the 
current Ethernet network. On networks without a DHCP server, or to simply override 
the automatic DHCP server function, delete the checkmark and enter the new “IP 
Address” settings desired. Remember that only a 0.0.0.0 address will trigger the 
DHCP addressing service, and only when the DHCP checkbox is enabled. 
 
IP ADDRESS: Enter a valid and unique IP address for use on the network to which the 
projector is currently connected. Upon the next power-up, this address will overwrite 
any previous IP address such as the projector’s factory-defined default (0.0.0.0), or 
one that has been assigned by a DHCP server or other user. An IP address entered 
here remains in effect until it is changed again. NOTES: Make sure the projector is 
connected to the network before changing its IP address. Make sure to re-boot. 
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 valid 
port number here. 
Broadcast Key 
Enter a checkmark if you want keypad commands sent to one projector to be relayed 
to all projectors in a serial network. Note that the 
Pr o j key will temporarily 
“override” the effect of a broadcast setting and allow you to control a specific 
projector when necessary. Make sure to remove the Broadcast Key checkmark when 
operating redundant networks. 
Backlight 
Toggle the built-in keypad lighting on/off. 
Front IR / Back IR 
NOTE: With v1.1 software, only one IR keypad protocol (A) is recognized at each of 
the projector’s IR sensors. Response can be toggled on or off independently in the 
menu as desired for your application. Use of multiple protocols as described here 
requires a software upgrade. 
As described in Section 2, the standard IR remote keypad is capable of sending data 
to the projector in either one of seven different protocols called 
A – G, depending on 
its internal jumper settings (default=
 A). Likewise, the front and rear IR sensors on 
the projector can be set to accept IR data accordingly, responding to one of the 
A – G 
protocols
, all or none. The projector’s “All” default is adequate for most single-
projector installations. Select a specific protocol to work with only certain projectors 
in a multi-projector group.  
						

							 OPERATION 
 
Roadie 25K User’s Manual 3-43 
Note that the front and rear IR sensors cannot respond to different protocols–
changing a protocol for either sensor to anything other than 
OFF changes the protocol 
for the other sensor too. For example, setting Front IR to 
E also changes the Back IR 
to 
E. If you want only one sensor to respond to a particular protocol, you must disable 
the other sensor by setting its protocol to 
OFF. 
To disable both IR sensors, you cannot use the IR remote keypad to select the second 
OFF setting. This safeguard prevents accidentally disabling a keypad while you are 
using it. Instead, use either the built-in keypad or the wired remote (optional) to set 
the remaining active sensor to 
OFF. The projector will no longer respond to an IR 
remote keypad. 
NOTES: The IR remote keypad for this projector is set at manufacture to Protocol 
A. See 2.14, Remote Keypad Protocols and Conversion for information about 
changing the keypad protocol for use with supporting software. 
Wired Keypad 
Select “On” to enable use of a wired remote keypad connected to either the rear of 
the projector (standard keypad with XLR connector) or the side input panel (optional 
keypad with phono-jack connector). The projector will then respond to incoming 
commands from either port. To disable the wired keypad, you must use a different 
keypad—the built-in or an IR remote keypad—to select “off”. This safeguard 
prevents you from accidentally disabling the wired keypad during use. 
In the Configuration menu, select 
the Geometry and Color submenu 
when you need to modify overall 
color performance and/or image 
geometry for all sources. 
Test Pattern 
Choose the desired internal test 
pattern, or select OFF to turn off a 
test pattern. Alternatively, use the 
Te s t key for cycling through test patterns. 
Keystone 
NOTE: If the optional ChristieTWIST module is installed, this option is Keystone 
and Warping, and activates a submenu for defining custom image shapes. Please 
refer to documentation included with your Christie TWIST module. 
Use to correct a keystoned image shape in which both sides of your image are 
inclined toward the top or bottom edge. Keystone is typically caused by tilting the 
projector in relation to the screen, so that the lens surface and screen are no longer 
parallel to each other.

Brightness Uniformity — SUBMENU 
Brightness Uniformity provides further refinement of displays already matched for 
their primary colors and overall light output. Use Brightness Uniformity to create an 
exceptionally smooth image in which no area appears brighter and/or more red, green 
or blue than another. In the Brightness Uniformity menu, enable the “Uniformity 
Enable” checkbox to access a multitude of adjustments for critical color light output 
control in specific areas throughout the image. Your settings apply as long as the 
“Uniformity Enable” checkbox is enabled and you are using a “User” color 
temperature defined by the Brightness Uniformity controls. To disable the Brightness 
Uniformity function, delete the “Uniformity Enable” checkmark. 
NOTE: See also 3.12, Using Multiple Projectors for the complete step-by-step 
procedure for achieving uniform brightness in adjacent displays. 
Edge Blending 
— SUBMENU 
The Edge Blending submenu provides a range of controls for smoothing together the 
overlapping bright edges of multiple adjacent projected images to create a single 
larger “seamless” image. These controls, which primarily affect whitelevels, are 
typically used in conjunction with mechanical lens blinders (optional), which are 
installed on the front of the projector and which primarily affect blacklevels. 
NOTE: See also 3.12, Using Multiple Projectors. 
Color Adjustments by X/Y, and Color Saturation — 
SUBMENUS 
NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color palette or “gamut”. 
Sometimes known as Comprehensive Color Adjustment™. 2) Factory-defined 
primary color levels, which ensure a specific color performance from projector-to-
projector, can be altered in the Service menu only. If you suspect alteration of these 
defaults, the factory settings can be recovered with selection of Reset to Factory 
Defaults?” in the Color Primary Settings submenu accessed via the Service menu 
(password-protected). 
From the factory, the projector can utilize 
any of the 3 pre-defined color 
performance settings identified at right 
(default=Max Drives), or colors can be 
driven on the basis of color temperature. 
For most applications, one of these 
options will produce accurate and realistic 
colors from a variety of sources. They can 
be applied at any time in the Advanced 
Image Settings menu (“Select Color 
Adjustment”), and are not adjustable. 
DEFINING “USER” COLOR GAMUTS: In some cases, you may find that none of the pre-
defined “Select Color Adjustment” options exactly suit your needs. For example, you 
may require a unique color range or gamut for a single projector or application, or 
you may need to precisely match colors across multiple adjacent displays. In such 
cases, use the Color Adjustments by X,Y or Color Saturation submenus to define the 
precise hue of each primary color component (red, green, blue, and white) used to 
generate the millions of colors produced in displays. You can create up to four 
custom color gamuts (User 1, 2, 3, or 4) with these adjustments.
