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 can receive the remote control signals.

Operate the projec-

tors 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. KEY LOCK or REMOTE ID * function

is also available. (Operating Guide → OPTION menu)

* Available only in optional remote control.

Tentative terms for the two projectors

For better understanding of the descriptions in this

manual, the following terms are used when explaining

the vertical stacking installation.

Set A : Projector placed underneath

Set B : Projector placed on top of Set A

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. Take care not to let the hot exhaust air from other

projectors enter the intake vents of the projector.

WARNING ►

Take a special care not to fall the stacked projectors.

• When stacking two projectors, make sure the elevator feet and heel of the

upper projector are inserted into the corresponding pockets of the lower

projectors. (



10)

• When using the Instant Stack function by piling up two projectors, you can

change the projection angle by adjusting the

elevator feet of the unit that is placed underneath.

(



7) Exercise care to prevent the stacked projector

from falling off or tipping over while adjusting the

elevator feet.

• A maximum of two projectors can be stacked. Do

not stack three or more projectors.

• Do not install the projectors that are stacked using

the stack pockets, elevator feet and heel of this

projector at a place higher than a person's height.

• Do not install the projectors that are stacked using

the stack pockets, elevator feet and heel of this

projector on a ceiling.

• Do not touch the stacked projectors except when

instructions are given in this manual. Do not hit the

projectors with any type of object.

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. (

8, 11, 15

)

• 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. Lower the volume until the symptoms disappear.

• 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. (

)

LW502/LWU502/LX602 User's Manual - Instant Stack Guide

020-001085-02 Rev. 1 (02-2018)

For safety reasons, read 1.1 Basic information and preparations (

3, 4

) carefully

before installation. In addition, take note of the following for proper use of Instant

Stack.

●Use the same model projectors.

●

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. KEY LOCK 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.
