If the projector is used with a screen size not listed in this manual, check the diagonal dimension (inch) of your
screen and calculate the projection distance using the following formulas.

Connection
Before connection, read carefully the instruction
manual for the device to be connected.
Turning off the power switch of the devices
before connecting cables.
If any connection cable is not supplied with the
device, or if no optional cable is available for
connection of the device, prepare a necessary
system connection cable to suit the device.
Video signals containing too much jitter may
cause the images on the screen to randomly
wobble or wafture.  In this case, a time base
corrector (TBC) must be connected.
The projector accepts the following signals:
video, S-Video, analog RGB and digital signals
from the PC.
Some PC models cannot be connected to the
projector.The pin-out and signal names of the S-VIDEO IN
terminal are shown in the diagram below.
The pin-out and signal names of the RGB2 input
terminal are shown in the diagram below.

Example of connecting with VIDEO devices
• When connecting with a video deck, be sure to use the one with a built-in time base corrector (TBC)
or use a TBC between the projector and the video deck.
• If nonstandard burst signals are connected, the image may be distorted.  If this is the case, connect a
TBC between the projector and the video deck.Attention

• When the main power of the main unit is turned off, also turn off the power of the PC.
• When stacking projectors using RGB/YP
BPR/YCBCRsignals, divide the signals at the signal source
and use RGB1 input for both projectors.  When the RGB1 OUT is connected to the external RGB
monitor, the image quality will be almost the same as that of checking monitors.
Note
Attention
• For the specifications of the RGB signals that can be applied from the PC, see the data sheet on
page 101.
• If your PC has the resume feature (last memory), the computer may not function properly until the
resume capability is disabled.
• The RGB 1 OUT (RGB 2) terminal will issue the signal that is connected to the input terminal of
RGB1.

Procedure of installation
Disconnect the power before installing the input module.
Remove the slot cover.
Slot cover Remove 2 screws.
Insert the input module.
Input moduleSlot
Fix the input module.
Register the input signal.

Tighten the two screws.
This projector needs to register the type 
of input signal after the installation of 
the input module.
(For details on the registration of the 
input signals, refer to pages 43 and 46.)

When installing the projector, it is necessary to connect signals to the input module in accordance with the
connecting equipment.
Refer to the following diagram to establish proper signal connection. 
• When switching multiple signals of the
same type and connecting to the same
input module (for example, when using
a signal chosen from multiple high-
vision signals), use a signal selector for
this purpose and connect it with the
projector through RS-232C. Those
signals can be used individually
according to the input terminal on the
signal selector.
• Digital signals cannot be connected to
the signal selector.
