User's Manual (detailed) Instant Stack Guide

Thank you for purchasing this product.

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.

1.1 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 settings 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. 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)

Operate

WARNING ► Do not place projectors directly on top of other projectors.

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.

1.1 Basic information and preparations (continued)

Introduction

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. (

) 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. (



)

2. Installation

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