Appendix A: Connecting to Additional Equipment105
Appendix A: Connecting to 
Additional Equipment
This appendix explains how to connect the projector to a desktop 
computer or Macintosh, or a high-end workstation. 
The following information is covered:

Installing the projector

Connecting to a PC desktop computer

Connecting to a desktop Macintosh

Connecting to a high-end workstation 
						

							106Appendix A: Connecting to Additional Equipment
Installing the Projector
The projector can be installed for three different viewing setups: front 
projection, ceiling mounting, or rear projection onto a 
semi-transparent screen.
To project from overhead, you’ll need to select 
Ceiling in the 
projector’s Advanced menu. To project from the rear, select 
Rear 
Proj
. See page 80 for more information.
If you’re ceiling-mounting the projector and you place it above screen 
level, you’ll have to tilt it down to position the image on-screen. This 
causes the image to lose its square shape. You can then correct the 
distortion by using the 
Keystone function in the projector’s menu 
system (see page 79).
If you place the projector’s lens so it’s level with the top of the screen, 
the image will be square and you won’t have to adjust it. If you place 
the lens lower than the top of the screen, you’ll have to tilt the 
projector upward if you want to fill the whole screen with the image. 
Connecting to an External Audio System
The projector’s internal speaker is loud enough for most rooms. 
However, if your installation requires maximum volume and sound 
quality, you can connect the projector to external speakers or a public 
address (PA) system. If you’ve connected a computer and video 
source, the projector will automatically switch the audio whenever you 
switch sources. (See page 32.)
To connect the projector to an external sound system, you will need 
an RCA-to-3.5 mm stereo audio cable, which may be included with 
your sound system, or may be purchased from an electronics store.  
						

							Appendix A: Connecting to Additional Equipment107
Before you start, make sure the projector and speakers or PA system 
are turned off.
1. Connect the cable’s 3.5-mm stereo miniplug to the projector’s 
Audio Out jack.
2. Connect the RCA plugs to the speaker or PA system. Insert the 
cable’s red plug into the 
Audio R jack, and the white plug into 
the 
Audio L jack of the external speaker system.
Connecting to a PC Desktop Computer 
You can connect the projector to any IBM compatible PC. This 
section includes instructions for the following:

Connecting the computer cable 

Connecting the mouse cable (if you want to use the remote 
control as a mouse)

Connecting an optional audio cable (if you’ll be projecting with 
audio)
When you connect the projector to a desktop computer, you cannot 
view your display on the computer monitor.
Follow the steps in each section for the cables you need to connect. 
Before beginning, turn off the projector and computer if they are on. 
						

							108Appendix A: Connecting to Additional Equipment
Connecting the Computer Cable
1. Disconnect the monitor cable from the video port on the back of 
the computer.

Computer port.
3. Connect the other end of the computer cable to the computer’s 
video port.
4. Tighten the screws on the connectors. 
						

							Appendix A: Connecting to Additional Equipment109
Connecting the Mouse Cable
To use the remote control as a mouse, follow the steps below. You’ll 
use a different mouse cable, depending on whether your computer has 
a round PS/2 mouse port or a flat USB port. 
1. Connect one end of the appropriate mouse cable to the projector’s 
Mouse/Com port or the USB port, as shown. 
 
2. Disconnect your mouse from the port on the back of your 
computer and replace it with the other end of the cable. (Your 
computer’s mouse will be disabled while you are using the remote 
control as a mouse.)

Connecting the Audio Cable
If your presentation includes sound and you want to use the 
projector’s built-in speakers, you can use a computer audio cable. The 
required cable (3.5-mm stereo miniplug cable) is available from 
computer or electronics dealers.
1. Connect one end of the audio cable to the 
Audio In jack on the 
projector.
   
2. Connect the other end of the audio cable to the speaker or 
audio out port on the computer’s sound card.

includes instructions for the following:

Connecting the computer video cable 

Connecting the mouse cable (if you want to use your remote 
control as a mouse)

Connecting an optional audio cable (if you’ll be projecting with 
audio)
When you connect the projector to a desktop Macintosh, you cannot 
view your display on the Macintosh monitor.
Follow the steps in each section for the cables you need to connect. 
Before beginning, turn off the projector and computer if they are on.
Connecting the Computer Cable
Follow these steps to connect the computer cable. You may not need 
to use the adapter as shown.
1. Disconnect the monitor cable from the video port on the back of 
the Macintosh.
2. Connect one end of the computer cable to the projector’s 
Computer port, as shown. 
 
3. Connect the other end of the computer cable to the video port on 
the Macintosh. 
note
Macintosh configurations 
vary. See your computer 
manual for the location of the 
ports needed to connect your

require a Macintosh adapter, 
which you may purchase 
from EPSON; see page 8.
