Introduction
1.1 Basic information and preparations
NOTICE ► Intellectual Stack can be operated only in pairs of the same model
p r o j e c t o r s .
► 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. ( 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.
• 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. ( 8 ) 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. ( 32 )
