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 via an RS-232C cable with necessary set-
tings 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.
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 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)
CAUTION ► Place the projector in a cool place with sufcient 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.
WARNING ► Do not place projectors directly on top of other projectors.
