Introduction

1.3 Basic information and preparation

Instant Stack

Instant Stack is the feature that brings you very convenient way to superimpose

the images projected by two projectors. The projector is specially designed to support the feature, and has some functions to support you to install two projec-

tors and superimpose the images.

Intellectual Stack and Simple stack

Instant Stack covers both of the following two features.

If you link two projectors with an RS-232C cable and make necessary setting on the projectors, the projectors will automatically collaborate to work under the set-

ting. This use is called as Intellectual Stack in this manual.

If you do not connect an RS-232C cable, the projectors will work individually. This

use is called as Simple Stack in this manual.

Remote control for Intellectual Stack and Simple Stack

In Intellectual Stack use, one projector is set as Main and the other is set as Sub. (

18) If you use Intellectual Stack, only the projector as Main can receive the

remote control signal. Even if you want to operate the other as Sub , you need to point at the Main with the remote control. If you use Simple Stack, both projectors can receive the remote control signal. To

avoid the operation by the remote control to being mixed up, it is recommended to operate one projector by the remote control and to operate the other by the control panel on the projector or wired remote. In this case the other projector should disable the remote control by KEY LOCK. (Operating Guide → OPTION menu)

Installation styles

There are following two styles to install two projectors. Instant Stack can support both of them.

Style 1 : Piling them up vertically Style 2 : Lining them up horizontally

This manual is mainly explained the installation of Style 1. If you wish to install

two projectors in Style 2, refer to the articles you need in this manual.

Tentative naming of two projectors

To be easy to follow the explanation, the following

Set

names are used in the manual for piling up installation.

Set A : A projector placed underneath Set B : A projector placed over Set A

Set

2. Installation

Before installation, read carefully Important safety instruction ( reason. And note the followings for proper use of the Instant Stack.

● When you use Intellectual Stack, until you set STACK MODE to SUB on one projector, both projectors can react to the remote control signal. For installation, it is recommended to operate one projector by the remote control and to operate the other by the control panel on the projector or wired remote. In this case the other projector should disable the remote control by

KEY LOCK. (

● Even if the images of Set A and Set B are fully superimposed once, it may shift

over time.

Adjust the images again to superimpose the image.

● It may be happened to make a mechanical noise and degrade image quality by sympathetic vibration with the two projectors if the volume of built-in speakers is

set to much higher.

In this case, check the volume setting on both projectors, and lower the volume to remove such phenomena. In case the image position is shifted, adjust it

again.

remote control by KEY LOCK if necessary.

Installation

2.3 Installation of the second projector (Set B)

Piling up projectors

1. Put Set B onto Set A, if you want to pile up two projectors. Make sure that the

heel on the bottom of Set B is right into the heel pocket on the top of Set A.

Keeping Set B on Set A, without

holding Set B up, push the elevator buttons of Set B to draw the

elevator feet. Make sure that the

feet are reached to the bottom of

the stack pockets on Set A.

CAUTION ►Be careful that when you pile up two projectors, a projector set over the other may

slide down.

3. Make the feet of Set B rotate two

revolutions counterclockwise to keep about 1 mm space between a protrusion at the bottom of Set B and the top case of Set A as shown in the right.

NOTE • Keeping Set B slightly away from Set A except the heel part is

required to avoid sympathetic vibration with the two projectors caused by sound out from built-in speakers.

• Be careful that if Set B is tilted more, the image of Set B may not be able to be superimposed to the image of Set A.

• If you have already used the elevator feet of Set A, make sure that the angle

to the horizontal line of both sets should be within 12 degrees.

Connecting projectors

If you wish to use Intellectual Stack, connect each CONTROL port on Set A and

Set B with an RS-232C cross cable.

Installation

Setting up Set B

1. Turn on Set B.

NOTE • After turning on Set B, make sure that the image of Set B is not

remarkably inclined compared with the image of Set A. If it is inclined too much, rotate the elevator feet of Set B to adjust the angle roughly. Check again that there is about 1 mm space between a protrusion at the bottom of

Set B and the top case of Set A.

2. Reset the adjustment by KEYSTONE and PERFECT FIT on Set B.

(Operating Guide → EASY MENU or SETUP menu)

NOTE • When you use PERFECT FIT, KEYSTONE cannot be operated. If it

is required to reset both functions, reset PERFECT FIT function rst.

3. Adjust image size and position of Set B with ZOOM ring, VERTICAL adjuster,

HORIZONTAL adjuster and FOCUS ring to fully overlap the image of Set A.

NOTE • Fine adjustment of image size and position later by electrical

function, such as KEYSTONE and PERFECT FIT, cannot widen the

image size, so it is important to fully overlap the image of Set A by optical adjustment.

• If you try to operate Set B with the remote control, Set A may react as well.

It is recommended to operate Set B with the control panel on Set B.

• If you install two projectors side by side, also adjust image size and position

of Set B to fully overlap the image of Set A.

• If you use Simple Stack, it is recommended to disable the remote control on Set B by KEY LOCK and operate it by the control panel, or to operate

it by a wired remote control, since Set A will react to the remote control. (
