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 
						

							76Appendix 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 46 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 rectangular shape. You can then correct the 
distortion by using the 
Keystone function in the projector’s menu 
system (see page 45). (You can’t use the 
Auto Keystone function 
when you’re projecting in ceiling or rear projection mode.)
If you place the projector’s lens so it’s level with the top of the screen, 
the image will be rectangular 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 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 a monitor to view your display on the desktop 
computer screen
■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)
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
1. Disconnect the monitor cable from the video port on the back of 
the computer. 
2. If you want to view the display on your computer monitor as well 
as the projector screen, connect the monitor cable to the 
projector’s 
Monitor Out port, as shown.
3. Connect one end of the computer cable to the projector’s 
Computer/Component Video 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.
1. Connect the square end of the USB mouse cable to the projector’s 
USB port, as shown. 
 
2. Disconnect your mouse from the USB port on the back of your 
computer and replace it with the other end of the cable. (Your 
computer’s mouse will be disabled.)
3. If necessary, configure your computer to work with a USB mouse. 
4. You can connect an external mouse to the USB Type A port or 
use the port as a USB hub to connect an external USB device, if 
you want. 
						

							Appendix A: Connecting to Additional Equipment79
Connecting the Audio Cable
If your presentation includes sound and you want to use the 
projector’s built-in speaker, 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 
Audio1 port 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.  
						

							80Appendix A: Connecting to Additional Equipment
Connecting to a Desktop Macintosh
You can connect the projector to a desktop Macintosh. This section 
includes instructions for the following:
■Connecting the computer video cable 
■Connecting a monitor to view your display on the desktop 
computer screen
■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)
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.
note
Macintosh configurations 
vary. See your computer 
manual for the location of the 
ports needed to connect your 
projector. Older models may 
require a Macintosh adapter, 
which you may purchase 
from EPSON; see page 7. 
						

							Appendix A: Connecting to Additional Equipment81
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. If you want to view the display on your computer monitor as well 
as the projector screen, connect the monitor cable to the 
projector’s 
Monitor Out port, as shown.
3. Connect one end of the computer cable to the projector’s 
Computer/Component Video port, as shown. 
 
4. Connect the other end of the computer cable to the video port on 
the Macintosh.  
						

							82Appendix A: Connecting to Additional Equipment5. If it doesn’t fit, you may have to use a Macintosh desktop adapter, 
which you can buy from EPSON (see page 7).
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.
6. Tighten the screws on the connectors.
Connecting the Mouse Cable
To use the remote control as a mouse, follow the steps below. 
1. Connect one end of the mouse cable to the projector’s USB port. 
 
2. Disconnect your Macintosh’s mouse cable. Connect the other end 
of the projector’s mouse cable to a USB port on your Macintosh. 
						

							Appendix A: Connecting to Additional Equipment83
3. You can connect an external mouse to the USB Type A port or 
use the port as a USB hub to connect an external USB device, if 
you want.
Connecting the Audio Cable
If your presentation includes sound and you want to use the 
projector’s built-in speaker, 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 
Audio1 port on the 
projector. 
  
2. Connect the other end of the audio cable to the speaker or 
audio-out jack on the Macintosh.

Connecting to a High-End Workstation
Your PowerLite projector is capable of remapping input resolutions 
up to 1600
×1200 pixels (on the PowerLite 73c) or up to 1280×1024 
pixels (on the PowerLite 53c). Since 1280
×1024 pixels is the default 
resolution for most leading workstations, your projector is ideal for 
displaying workstation video output.
There is no standard for workstation video output. Workstations that 
follow the SXGA standard and use the HD15 (standard VGA) 
connector won’t need an adapter cable or any special connection 
device. However, your system may vary; contact your computer dealer 
if you need help connecting your workstation.
