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 an 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 using an RS-232C cable with necessary

settings performed on the projectors, these two projectors 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 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, 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.

User's Manual - Instant Stack Guide 020-001307-01 Rev. 1 (10-2017)

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.

► Use the same type of lens 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.

• 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 can control the Sub projector. This feature is known as Intellectual

Stack. (

) When Intellectual Stack by means of RS-232C feature is used,

RS-232C communication cannot be used to control the projector. If you want

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. (

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.
