To loop a single incoming video signal input (connected at the video decoder)
through to another projector or display device, use the empty connector(s) adjacent to
this same input as described below.
Composite Video Loop Through
CONNECTIONS: See Figure 2.22. From your source, connect a composite video signal
to 
INPUT 3 using either the small phono plug or the adjacent BNC. Connect a second
cable from whichever 
INPUT 3 connector is free to one of the composite video inputs
of the next display device or projector. Continue this looping method for each
projector, using either the phono plug or the adjacent  BNC as input into 
INPUT 3,
then using the other connector as an output (i.e., loop through). Whether you use the
BNC or the phono plug as input or output depends on the type of cable you have on
hand and what type of connectors are on each end.
VIDEO TERMINATION: In the Video Options submenu, make sure “Video
Termination” is checked for the final projector only. All other projectors must have
this option unchecked in order for the signal to continue. For other types of display
devices in the chain, typically a “Hi-Z” switch position is needed.

S-Video Loop Through
CONNECTIONS: See Figure 2.23. From your source, connect an S-video source signal
to 
INPUT 4 using either the 4-pin mini DIN or the 2 adjacent BNCs labeled Y and C.
Connect a second cable from whichever 
INPUT 4 connector is free to one of the S-
video inputs of the next display device or projector. Continue this looping method for
each projector, using either 4-pin mini DIN or the 2 adjacent BNCs as input into
INPUT 4, then using the other connector(s) as an output (i.e., loop through). Whether
you use 4-pin mini DIN or the 2 adjacent BNCs as input or output depends on the
type of cable you have on hand and what type of connectors are on each end.

If you want to use an extra video source in addition to the video source(s) connected at
INPUT 3 or INPUT 4 connect either a Composite or S-Video source to INPUT 1 as shown in
Figure 2.24. Do not connect both types here simultaneously. NOTE: For additional video
inputs, install an optional Composite/S-Video Input Module at 
INPUT 2.
Figure 2.24. Connecting an Extra Video Source to Input 1
Optional modules allow you to increase your total number of inputs and/or
accommodate different signal types, whether analog or digital. Any one of these
modules can be installed in the area labeled 
INPUT 2. They include:
• RGB 500 Input Module
• RGB 400 Active Loop Thru Input Module
• RGB 400 Buffered Amplifier Input Module
• Composite/S-Video Input Module
• PC250 Analog Input Module
• Serial Digital Input Module
• Digital HDTV Module
• DVI Input Module
Alternatively, the analog interfaces (i.e., non-digital) can be installed in a Marquee
Case/Power Supply or Marquee Switcher, if desired, and used with the projector.
NOTES: 1) Optional digital interfaces cannot be used in a Marquee Case/Power
Supply or Switcher. 2) Connect analog HDTV signals directly to 
INPUT 1 or to any Extra Video

earlier projectors is not needed or recommended . 4) See Appendix F, Optional
Input Modules for a brief description of each interface.
You may wish to use one or more external Marquee Signal Switchers or a third party
switcher in order to significantly increase the number of sources you can select. If
you are using a Marquee Signal Switcher, connect the switcher’s RGB output to
INPUT 1 and connect an RS-232 serial communication cable between the switcher and
the projector serial port labeled 
SWITCHER (see Figure 2.25). The switcher
communication link (permanently set at 9600 baud) enables you to access inputs
connected to the switcher in the same manner as those connected directly to the
projector. For most other third-party switchers, connect and access sources according
to the documentation provided with that switcher.
NOTE: Make sure any Marquee Signal Switcher connected directly to the projector
is set as “Switcher #1”. If it is not, unplug the switcher and turn the thumbwheel to
“1” before plugging back in and connecting to the projector and/or network.
Figure 2.25. Connecting a Marquee Signal Switcher
If you are using more than one Marquee Signal Switcher, daisy-chain the RS-232
switcher inputs/outputs together to form a complete network of inputs accessible
from the projector (you can network up to 9 switchers), and connect Switcher #1 to
the projector as shown in Figure 2.25. In addition, connect the RGB output from each
switcher to its matching slot on switcher #1–for example, connect the RGB output
from switcher #2 to slot #2 on switcher #1, and the RGB output from switcher #3 to
slot #3 on switcher #1. Note that slots used in this manner on switcher #1 are no
longer recognized as inputs to the projector–if you select a slot location that is
connected to another switcher’s RGB output, the projector will display the “no input
signal” error message. Connectin

							INSTALLATION & SETUP
Roadie S12/X10 User’s Manual2-21
Plug the twist-locking 3-prong end of the integral line cord (30-amp, with L6-30
plug) into an appropriate grounded AC source. Twist to secure. Input voltage to the
projector must be capable of supplying between 200 and 240 VAC, 50 or 60 Hz. The
power source must be capable of supplying 2800 watts of power to the projector. See
Section 5, Specifications for complete power requirements.
 WARNING 
Do not attempt operation if the AC supply is not within
the specified voltage and power range.
Do not alter the line cord.
 Caution: Once the projector is turned off, the lamp cooling fans will continue to
run for approximately five minutes to ensure that the projector and lamp have
sufficiently cooled, at which point the fans will automatically shut off. To avoid
thermal stress to the lamp, never unplug the line cord while the lamp cooling fans are
running. It is recommended that the main AC I/O switch (circuit breaker) remain in
the ON position at all times.
The projector is set up at the factory for use in a front screen, floor mount orientation.
If your initial installation is ceiling mount or rear screen, displayed images may be
upside down and/or reversed. To correct, you must change the image orientation
from within the Menu
Preferences menu (you may
prefer to do this before
installing the projector in its
final position/orientation).
In the Menu Preferences
menu, highlight and select
the Image Orientation pull-
down list. Select from Rear,
Inverted Rear, Front or
Inverted Front according to
your intended installation.
See Section 3, Operation for
further information.
For most installations, the lens surface of the projector is parallel to the screen—this
prevents major keystoning of the image (i.e., an image with non-parallel sides). In
addition, the projector must be kept level from side-to-side in order for the lamp to
function safely. To make small corrections to the projectors level, rotate each leg as
necessary to raise or lower.
For angled installations, see
“Special Mounting” under
2.3, Projector Position and
Mounting earlier in this
section. To adjust
keystoning through
software, see Section 3.

Once the projector is properly set up and projecting an image, you are ready to make
quick adjustments of the motorized lens. Lens control is accessed by pressing the 
Lens
key on one of the keypads, which will display the Lens Control menu of options.
NOTE: Refer to Section 3 if you need help in navigating the menu.
If you have a zoom lens installed, adjust the zoom slidebar in the Lens Control menu
to increase or decrease the size of your image at the current throw distance.
In the Lens Control menu, adjust the focus slidebar until you obtain the best overall
image clarity.
To ensure that the image is positioned as desired, adjust either or both offset slidebars
in the Lens Control menu. Try to achieve the desired overall image position and best
brightness while obtaining a rectangular image. If the brightness looks uneven, or the
edges do not look perfectly straight, the projector may not be in the optimal position
for your screen. See 2.3, Projector Position and Mounting for full details about lens
offset ranges for specific lenses and projector models.
Further display adjustments are available through keypad commands and on-screen
menus—refer to Section 3, Operation.
NOTE: Communication software is required for serial control. Contact your dealer
for details.
You may wish to use equipment other than the keypad for controlling the projector or
for performing other special functions. Such equipment—such as most personal
computers—requires a serial interface for sending and receiving communications
through the serial ports on the projector. Note that there are two different types of
serial communication ports on this projector as described below.
RS-232 Ports
From most computers, connect an 
RS-232 serial communication cable between the
computer and the projector serial port labeled 
RS-232 IN—this 9-pin D connector port
is located near the bottom center of the projectors front control panel (see Figure
2.27). Then set the projector baud rate to match that of the computer (changing the
baud rate is described in 3.7, Configuring System Parameters).
NOTE: Refer to Appendix D for complete cable wiring details.

Figure 2.27. RS-232 Serial Connection to a Computer
RS-422 Ports
Some computers can provide 
RS-422 serial communications (often through a plug-in
adapter or external converter) rather than the more common RS-232. RS-422
communication has differential “transmits-and-receives” and is generally better
suited for long distances than is RS-232 communication. RS-422 is not compatible
with RS-232—connecting one to the other could damage the equipment at either end.
If you wish to control the projector with a computer and/or other controlling device
(such as the Two-Way Controller) having RS-422 capability, connect 
RS-422 serial
communication cables between the computer (or other device) and either (or both) of
the projector serial ports labeled 
RS-422—these 6-pin XLR connector ports are
located near the upper right corner of the projectors front control panel (see Figure
2.28). Use an 
RS-422 port only if your equipment has RS-422 capability—always
first consult the documentation supplied with your equipment.
Figure 2.28. RS-422 Serial Connection to a Computer
 WARNING 
Do not use an RS-422 port unless you are using a
computer with RS-422 capability. The voltage levels of
this signal can damage incompatible equipment.
You may wish to use one or more external Marquee Signal Switchers or a third party
switcher in order to significantly increase the number of sources you can select. If

INPUT 1 and connect an RS-232 serial communication cable between the switcher and
the projector serial port labeled 
SWITCHER (refer back to Figure 2.25). The switcher
communication link (permanently set at 9600 baud) enables you to access inputs
connected to the switcher in the same manner as those connected directly to the
projector. For most other third-party switchers, connect and access sources according
to the documentation provided with that switcher.
NOTE: See 2.4, Source Connections, “Connecting a Switcher” for complete details.
Serial Communications
RS-232 NETWORK: To control multiple projectors with a computer/controller having
an RS-232 interface, first set them all to the same baud rate needed, then chain the
projectors together by connecting the 
RS-232 OUT connector of the first projector
(already connected to the computer/controller) to the 
RS-232 IN connector of the next
projector in the chain.
Figure 2.29. Adding Another Projector via RS-232
RS-422 NETWORK: To control multiple projectors with a computer/controller having
an RS-422 interface, first set them all to the same baud rate needed, then chain the
projectors together by connecting the 
RS-422 PORT 2 connector of the first projector
(already connected to the computer/controller) to the 
RS-422 PORT 1 connector of the
next projector in the chain.

							INSTALLATION & SETUP
Roadie S12/X10 User’s Manual2-25
For either type of network, continue connecting projectors in this manner until
you’ve reached the last projector in the chain, so that only the last projector has an
empty 
RS-232 OUT (or RS-422 PORT, if applicable). See examples below.
Figure 2.31. Assorted Networks
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 3.7, Configuring System Parameters if you need help changing the
projector baud rate from its default of 19200.
NOTES: 1) To avoid damage, connect only properly wired serial communication
cables. See Appendix D for details.  2) It is recommended that each RS-232
communication cable be no more than 25 feet in length. Use high quality cables.

Roadie S12/X10 User’s Manual
In a typical network, broadcast serial communications or messages destined for a
specific projector travel through all serial ports in each projector regardless of
whether the messages originate from an RS-232 or RS-422 source (refer back to
Figure 2.31, bottom example). The communication path depends on the serial cabling
connected at each projector.
You may prefer the option of two separate communication paths—RS-232 or RS-
422—in your network, essentially creating a redundant “back-up” communication
path that can take over should a failed projector (or controller) prevent
communications via the other path. For this setup, connect each projector to the next
using both RS-232 and RS-422 ports.
Then enable the “Split Network”
setting in the Communications menu
for each projector present so that RS-
232 communications remain on RS-
232 paths only and RS-422
communications remain on RS-422
paths only (Figure 2.32). Each
projector can then receive and send
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
(whether it is RS-232 or RS-422). Note that the “Broadcast Key” option is OFF.
 IMPORTANT 
Whenever downloading new projector software to networks, use a
single-route network only. DISCONNECT any redundant serial cabling
and UNCHECK the “Split Network” checkbox for each projector.
Two Different “Splits”
There are two different split network configurations possible (Figure 2.33). 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., RS-232) to
one physical end of the network and the other controller standard (e.g., RS-
422) at the other physical end of the network. Make sure the “Split Network”
option is enabled 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 RS-232/RS-422 adapter.
B. SPLIT NETWORK WITH TWO CONTROLLERS– If you have two controllers (one
RS-232 and one RS-422) 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 RS-232 and RS-422 ports as shown.
Make sure the “Split Network” option is enabled in the Communications
menu. Now, if either controller fails, you can simply switch to the other
controller and communicate via the other standard. Back-u

Each projector can be assigned a unique 3-digit projector number (for example, 001).
These numbers are necessary when you are working with multiple linked projectors,
enabling you to direct commands to a certain projector rather than always
broadcasting to the entire network. For complete information on how to assign
projector numbers, see 3.7, Configuring System Parameters.
NOTE: To loop a single incoming video source through to another projector or
display device on a network, see Video Loop Through in 2.4, Source Connections.
At manufacture every keypad is assigned “A” as its default protocol, which is simply
a collection of settings that determine how the keypad operates. Once assigned, this
protocol remains in effect until it is changed—that is, the keypad will operate as it
currently does until you change its protocol. Projector Numbers
