1. Introduction 1.1 Basic information and preparations Instant Stack Instant Stack is a feature that allows you to easily superimpose images projected from two projectors. Intelligent Stack and Simple Stack Instant Stack includes the following two features: When two projectors are connected via an RS-232 cable and proper menu set- tings have been selected, these two projectors will automatically operate in syn- chronization with each other. This is known as Intelligent Stack in this manual. The two projectors can also operate individually without an RS-232 connection. This is known as Simple Stack in this manual. Remote control for Intelligent Stack and Simple Stack For Intelligent Stack, one projector is set as Main and the other is set as Sub. Only the Main projector is capable of receiving 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 Intelligent Stack. For Simple Stack, both projectors can receive remote control signals. To avoid incorrect operations with the remote control, we recommend to operate both pro- jectors 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 receiver on the other projector with the KEY LOCK feature. (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 sufficient ventilation. Keep a space of 30 cm or more between the side of the projector and other objects such as a wall. Keep a space of 30 cm or more between 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 the projectors directly on top of other projectors.

NOTICE ► Intelligent Stack can be only be used with pairs of the same model projectors. ► A maximum of two projectors can be used in an Intelligent Stack. ► Depending on the installation and surrounding environment, images projected from the two projectors may not superimpose completely. Images cannot superimpose well 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 temperatures. Wait for a minimum of 20 minutes before beginning to adjust the superimposed images. • Image positions may shift due to temperature changes, vibration, or shock caused from 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 settings on both projectors. • When two projectors are connected using an RS-232 cable, the Main projector will be able to control the Sub projector. This feature is known as Intelligent Stack. (8) When Intelligent Stack is used with an RS-232 cable, RS-232 communication cannot be used to control the projector. If you wish to control the projectors from a computer, use the LAN connection on any of the projectors. • When Intelligent Stack is used, the some menu options and settings are restricted. Refer to this manual for details. (30)

installation. In addition, review the following for proper use of Instant Stack. • Use the same model projectors. • Arrange the projectors side by side. • Verify the projection screen is perpendicular to the projectors. • Project images larger than the minimum screen size shown in the table. The greater the distance between the projectors, the larger the screen size needs to be. L: distance [cm] Minimum screen size [inch] 30 200 50 250 100 380 ● If you control one projector with the remote control during installation, we recommend that you operate the other with the control panel or a wired remote control. In this case, disable the remote control receiver on the other projector with the KEY LOCK feature. (Operating Guide → OPTION menu) ● Images from Set A and Set B may superimpose well but the image positions can shift over time.

the Main and Sub projectors. There are various methods to input the image to the projectors. This chapter describes different ways to connect the cables. Read this chapter to find a method that meets your needs. 4.1 Connecting an RS-232 cable If you are using Intelligent Stack, connect an RS-232 null modem cable between the CONTROL ports on the Main and Sub projectors. (8) This connection is not required if you are using Simple Stack. 4. Connecting cables NOTE • If Simple Stack without an RS-232 connection is used, the Main and Sub projectors described below do not exist. Main in this chapter refers to one projector and Sub to the other projector. • For details on input port specifications, refer to Connecting with your devices (Operating Guide → Setting up) and Connection to the ports. (Operating Guide - Technical) NOTE • If the RS-232 cable becomes disconnected between the two projectors operating in Intelligent Stack mode, the projectors will exit from Intelligent Stack and start to operate individually. Intelligent Stack will not restart even if the cable is reconnected. Follow the procedures below to restart Intelligent Stack: (1) After the cable has become disconnected, do not operate the projectors for more than 10 seconds to allow the projectors to recognize the cable disconnection. (2) Turn off both projectors and allow them to cool sufficiently. (3) Reconnect the two projectors with the RS-232 cable and turn them on again. Intelligent Stack will restart.
