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.
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 called as
Intellectual Stack in this manual.
The two projectors operate individually without the RS-232C connection. This is
called 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 with remote control and from
the control panel, refer to 3.5 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 with
the control panel or a wired remote control. KEYLOCK or REMOTE ID function is
also available. (Operating Guide → OPTION menu)
If you require more information on Instant Stack, please consult your dealer.
CAUTION ► Place the projector in a cool place with sufcient ventilation.
Keep a space of 50 cm or more between a side of the projector and other
objects such as a wall. Keep a space of 50 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
DWU951/DHD951/DWX951/DXG1051 User's Manual - Instant Stack Guide
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.
► Please use the same type of lens for both projectors.
► Please set the same Color Wheel settings for both projectors.
► 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.
• When two projectors are connected using the RS-232C cable, the Main
projector will be able to control the Sub projector. This feature is called as
Intellectual Stack. (
5 ) 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. (

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.
● Use the same model projectors.
● Arrange the projectors side by side.
● Make sure the projection screen is
perpendicular to the projectors.
● Project images larger than the recommended
screen size shown in the table. The greater
the distance between the projectors, the
larger the screen size needs to be.
● To avoid incorrect operations with the remote control, it is recommended to operate
with the control panel or a wired remote control if you control one projector with the
remote control during installation. KEYLOCK or REMOTE ID function is also available.
(Operating Guide → OPTION menu)
●Images from Set A and Set B may superimpose well but the image positions can shift
over time. Readjust to superimpose the images.
2.1 Preparing for Intellectual Stack
When using Intellectual Stack via RS-232C connection, ensure the following settings are
set on the two projectors. Otherwise, the Intellectual Stack menu cannot be operated.
●STANDBY MODE in SETUP menu: NORMAL
(Operating Guide → SETUP menu)
●COMMUNICATION TYPE under COMMUNICATION in SERVICE menu: OFF
(Operating Guide → OPTION menu)
●STACK LOCK in SECURITY menu: OFF
When STACK LOCK is set to on, menus related to Instant Stack cannot be operated. It is
therefore necessary to set it to off during installation and menu setting.
(1) Use the ▲/▼/◄/► buttons to go into the following menu.
ADVANCED MENU > SECURITY (> ENTER PASSWORD) > STACK LOCK
STACK LOCK dialog will appear on screen. (Operating Guide
