Note
•
Allow a margin of error in the value in the diagrams above.
• When the distance from the lens center to the bottom of the image [H] is\
 a negative number, this indicates
that the bottom of the image is below the lens center.
• See page 
18  about projection distance [L] and distance from the lens center to the b\
ottom of the image [H].

Connections
Connecting to a Computer
Before connecting, ensure the power cord of the projector from the AC outlet is unplugged,
and that the devices to be connected are turned off. After making all connections, turn on the
projector and then the other devices. When connecting a computer, ensure that it is the last
device to be turned on after all the connections are made.
Ensure the operation manuals of the devices to be connected have been read before making connections.

* When using the ø3.5 mm mono audio cable, the volume level will be half of when using the ø3.5 mm stereo audio cable.
Note
• See page  65 “Computer Compatibility Chart” for a list of computer signals compatible with the projector.
Use with computer signals other than those listed may cause some of the functions to not work.
• A Macintosh adaptor may be required for use with some Macintosh computers. Contact your nearest
Macintosh Dealer.
• Depending on the computer you are using, an image may not be projected unless the computer’s
external output port is switched on. (e.g. Press “Fn” and “F5” keys simultaneously when using a
SHARP notebook computer).  Refer to the specific instructions in your computer’s operation manual to
enable your computer’s external output port.

Connecting to Video Equipment
The image quality is highest in order of the Component signal, the RGB s\
ignal, the S-video signal and the
Video signal. If your audio-visual equipment has a component output terminal or RGB output terminal, use the
COMPUTER/COMPONENT terminal 1 or 2 on the projector for video connection.
When connecting video equipment with a DVI output terminal
Note
•Select the input signal type of the video equipment. See page  47.
• While the projector is connected to video equipment that has an HDMI out\
put terminal, only the video
signal can be input to the projector. (Connect the AUDIO input terminal for audio input.)
• Depending on specifications of video equipment or HDMI to DVI digital cable, the signal transmission
may not work property. (The HDMI specification does not support all connections to video equipment
that has HDMI digital output terminal using HDMI to DVI digital cable.)
• For details on compatibility for connection, see support information on DVI connection provided by the
video equipment manufacturer.
When connecting video equipment with component video output terminal
(Connecting to COMPUTER/COMPONENT 1 or 2: The illustration shown below is for the former.)
Note
• When you connect video equipment with a 21-pin RGB output (Euro-scart) to the projector, use a
commercially available cable that fits in the projector terminal you want to connect.
• The projector does not support RGBC signals via the Euro-scart.

Controlling the Projector by a Computer
When the RS-232C terminal on the projector is connected to a computer, the computer can be used to control
the projector and check the status of the projector. Refer to the “SETUP MANUAL” contained on the supplied
CD-ROM for “RS-232C Specifications and Commands”.
When connecting to a computer using an RS-232C serial control cable and a DIN-D-sub RS-232C adaptor
Note
•The RS-232C function may not operate if your computer terminal is not correctly set up. Refer to the
operation manual of the computer for details.
Info
•Do not connect the RS-232C cable to a port other than the RS-232C terminal on the computer. This may
damage your computer or projector.
•Do not connect or disconnect an RS-232C serial control cable to or from the computer while it is on. This
may damage your computer.
