Features
This projector can be used with another projector of the same model to project an
image on the same screen using the Instant Stack feature.
The two projectors can be operated simultaneously to make the image brighter.
Moreover, if you connect two projectors with RS-232C cross-over cable, it turns to
a kind of intellectual stacking system. The two projectors can work alternately by
themselves, and once one projector has an accident the other voluntarily starts to
work to keep your presentation going.
These features, generically called Instant Stack, provide you with the broad use.

1. Introduction
1.1 Basic information and preparations
Instant Stack
Instant Stack is a feature that allows you to superimpose images projected from
two projectors easily.
Intellectual Stack and Simple Stack
Instant Stack includes the following two features.
When two projectors are connected via an RS-232C cable with necessary set-
tings performed on the projectors, these two projectors will automatically operate
in synchronization with each other according to the settings. This is known as
Intellectual Stack in this manual.
The two projectors operate individually without the RS-232C connection. This is
known as Simple Stack in this manual.
Remote control for Intellectual Stack and Simple Stack
For Intellectual Stack, one projector is set as Main and the other is set as Sub.
Only the Main projector is capable of receiving the remote control signals.
Operate
the projectors from the control panel of the Main projector or with the remote control
pointing at the Main projector. For details on operating by remote control and from the
control panel, refer to 3.7 Important Information for Intellectual Stack.
For Simple Stack, both projectors can receive the remote control signals. To avoid
incorrect operations with the remote control, it is recommended to operate both
projectors with the control panel or a wired remote control, or one projector with
the remote control and the other with the control panel or a wired remote control.
In this case, disable the remote control receiving on the other projector with the
KEY LOCK feature. (Operating Guide → OPTION menu)
CAUTION ► Place the projector in a cool place with sufcient ventilation.
Keep a space of 30 cm or more between a side of the projector and other
objects such as a wall. Keep a space of 100 cm or more between the two
projectors, especially if you are installing the projectors side by side. Take care
not to let the hot exhaust air from other projectors enter the intake vents of the
projector.
WARNING ► Do not place projectors directly on top of other projectors.

Introduction
1.1 Basic information and preparations (continued)
NOTICE ► Intellectual Stack can be operated only in pairs of the same model
projectors.
► A maximum of two projectors can be used as Intellectual Stack.
► Depending on the installation and surrounding environment, images
projected from the two projectors may not superimpose well enough. The
images cannot superimpose well enough especially when the screen is slanted,
deformed or the surface is uneven.
• Images projected immediately after turning on the projectors are unstable due
to rising internal temperature. Wait for more than 20 minutes before starting
to adjust the superimposed images.
• The image positions may shift due to temperature change, vibration, or shock
caused by hitting the projector. Install the projectors in a stable environment
when using Instant Stack. If the image positions are shifted, readjust the
images. (
6, 8, 11 )
• The image positions may shift over time due to the tension and the weight of
the connecting cables. Make sure not to impose any load on the projectors
when arranging the cables.
• If the volume level of the built-in speakers is too high, noise may occur and
the image quality may deteriorate. In this case, check the volume setting on
both projectors.
• When two projectors are connected using the RS-232C cable, the Main
projector will be able to control the Sub projector. This feature is known as
Intellectual Stack. (
8 ) When Intellectual Stack by means of RS-232C
feature is used, RS-232C communication cannot be used to control the
projector. If you wish to control the projectors from a computer, use the LAN
connection that is connected to any of the projectors.
• When Intellectual Stack is used, the operations or settings of some functions
are restricted. Refer to this manual for details. (
30 )

5
For safety reasons, read 1.1 Basic information and preparations ( 3, 4 ) carefully
before installation. In addition, take note of the followings for proper use of Instant
Stack.
● When using Intellectual Stack, both projectors will respond to the remote control
signals until STACK MODE on either projector is set to SUB.
If you control one projector with the remote control during installation, it is
recommended to operate the other with the control panel or a wired remote
control. In this case, disable the remote control receiving on the other projector
with the KEY LOCK feature. (Operating Guide → OPTION menu)
● Images from Set A and Set B may superimpose well but the image positions
can shift over time.

● All buttons except the STANDBY/ON button on the control panel of the Sub
projector are disabled. Operate the projectors with the control panel of the Main
projector or the remote control.
● Pressing the STANDBY/ON button of the Sub projector does not allow you to
turn off only the Sub projector. The Main and Sub projectors turn off when the
button is pressed for more than 3 seconds. And pressing the button does not
turn on the Main or Sub projector.
● The Main projector is capable of receiving the remote control signals but not the
Sub projector so the remote control should be pointed at the Main projector.
● <Only for CP-X8160, CP-WX8255 and CP-WU8450>
Each Status Monitor can also be operated individually from the respective
control panel of the Main and Sub projectors. Only the monitor on the projector
that has been turned on can be operated with the remote control.
● If a wired remote control is used, connect the cable to the Main projector instead
of the Sub projector.
● For simple PC mouse & keyboard functions, connect both the Main and Sub
projectors to your computer with USB cables. (Operating Guide → Using as a
simple PC mouse & keyboard)
● AUTO SEARCH function is disabled when the projector is used in Intellectual
Stack.
● Network communication to Sub and Web Control on Sub cannot turn on the Sub
projector. The Sub projector can only be controlled through the Main projector.
● The Web Remote Control function of the Sub projector is disabled. (Network
Guide → 3.1.11 Remote Control)
● If you try to turn on the projectors using the Power on & Display on feature on
the Messenger function, the projectors will exit Intellectual Stack and display the
specied message. To start Intellectual Stack again, re-select MAIN/SUB on
both projectors in the STACK MODE dialog, or turn off and on both projectors
again.
