Appendix A: Connecting to 
Additional Equipment
This appendix explains how to connect the projector to a desktop 
computer or Macintosh, high-end workstation, more than one 
computer, or a DVI video source. It also provides guidance on setting 
up the projector in a permanent installation. 
The following information is covered:

Installing the projector

Connecting to a PC desktop computer

Connecting to a desktop Macintosh

Connecting to a second computer

Connecting to a high-end workstation

Connecting to a DVI video source

							78Appendix 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, as shown: 
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 “Setting Advanced Features” on page 53.
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 “Customizing Projector Features” on page 51) or by using 
the 
Keystone button on the projector’s control panel.
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. 
Controlling the Projector from a Computer
If you want to be able to control the projector’s settings from a 
computer, you can install the EMP Link V program on the Projector 
Software CD-ROM. You’ll also need a serial cable to connect the 
projector to the computer.

							Appendix A: Connecting to Additional Equipment79
To install EMP Link V, insert the Projector Software CD-ROM in 
your CD-ROM drive and follow the instructions on the screen. The 
installation program also installs the EMP Link V User’s Guide on your 
hard disk. You can access this manual in the EMP Link V folder for 
complete instructions on using the program. 
Connecting to an External Audio System
The projector’s internal speakers are 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 multiple audio and video 
sources to the projector, the projector will automatically switch the 
audio source along with the video source whenever the user chooses a 
different video source. (See “Switching Between Picture Sources” on 
page 27 or 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. 
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 and computer monitor cable

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

Connecting the audio cable (if you’ll be projecting with audio)
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 and Monitor Cables
This illustration shows the connections you’ll be making. For details, 
follow the steps below.
1. Disconnect the monitor cable from the video port on the back of 
the computer. 
2. If you’ll be viewing the video on your computer monitor as well as 
the projector screen, connect the monitor cable to the projector’s 
Monitor Out port, as shown. (This is useful when you need to 
view the video output but the projection screen is behind you.) 
3. Connect one end of the computer cable to the projector’s 
Computer 1 (analog VGA) port.

4. Connect the other end of the computer cable to the computer’s 
video port.
5. Tighten the screws on the connectors.
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 the round end of the mouse cable to the projector’s 
Mouse 1 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.)
note
If you have a PC with a 
serial mouse port, you’ll need 
a serial mouse cable. See your 
projector dealer to obtain the 
correct cable.

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

							84Appendix A: Connecting to Additional Equipment3. Connect the other end of the computer cable to the video port on 
the Macintosh. If it doesn’t fit, you may have to use a Macintosh 
desktop adapter, which you can buy from EPSON (see page 8). 
To use the adapter, remove its cover as 
shown and set its DIP switches according 
to the resolution you want to use, such as 
16-inch mode. See your Macintosh 
documentation for instructions.
Replace the cover and connect the 
adapter to the free end of the computer 
video cable. Then plug the cable (with 
the adapter) into the video port on your 
Macintosh.
4. If you also want to view the presentation on your computer’s 
monitor, connect the monitor cable to the projector’s 
Monitor 
Out
 port. (If necessary, attach a Macintosh monitor adapter to the 
monitor cable, as shown below, and then connect the adapter to 
the projector’s 
Monitor Out port.)
5. Tighten the screws on the connectors.
