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. 
The USB cable also provides audio support. If your computer 
supports USB and your presentation includes sound, you can play it 
through the projector’s speakers by connecting the USB cable. 
1. Connect the square end of the USB cable to the projector’s 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.) 
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.

Connecting the Audio Cable
If your presentation includes sound and you want to use the

not need a separate audio cable. 
1. Connect one end of the audio cable to the 
Audio 1 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.

Connecting to a Desktop Macintosh
You can connect the projector to any desktop Macintosh. This section 
includes instructions for the following:

Connecting the computer cable

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

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, make sure the projector and computer are turned 
off. If you need help with positioning the projector, see page 10.
Connecting the Computer Cable
1. Disconnect the monitor cable from the video port on the back of 
the Macintosh.
2. If you’ll be viewing 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. 
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 
set, which you may purchase 
from EPSON; see page 7.

3. Connect one end of the computer cable to the projector’s 
Computer 2/ Component Video port, as shown. 
 
4. 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 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.
5. Tighten the screws on the connectors.

Connecting the Mouse Cable
To use the remote control as a mouse follow the steps below. If the 
Macintosh has a USB port, you can use the USB mouse cable 
included with the projector. If it has a round mouse port, you’ll need a 
Macintosh mouse cable; see your projector dealer for help in obtaining 
the correct cable.
The USB cable also provides audio support on Mac OS 9.0 and 9.1. If 
your Macintosh supports USB and your presentation includes sound, 
you can play it through the projector’s speakers by connecting the 
USB cable. 
1. Connect the square end of the USB 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.

Connecting to a Second Computer
To connect a second computer to the projector, you need to use the 
projector’s 
Computer1 port. You’ll need the optional DVI-analog 
cable, unless the computer supports DVI (Digital Visual Interface) 
video.
1. Connect one end of the cable to the computer’s video port.
2. Connect the other end to the projector’s 
Computer1 port as 
shown.
3. To display images properly, make sure the 
Comp1 Input option 
in the projector’s Setting menu is set correctly. See page 56 for 
instructions.
4. If you want to hear the computer’s audio through the projector, 
you’ll need to connect the USB cable or purchase an RCA-to-
3.5 mm stereo cable (available from your electronics store or video 
dealer). 
Insert the cable’s 3.5-mm plug into your computer’s audio-out 
port. Then attach the connectors at the other end of the cable to 
the projector’s 
Audio 2 jacks, matching the white plug to the 
L jack and the red plug to the R jack.

Connecting to a High-End Workstation
There is no across-the-board standard for workstation video output. 
However, your PowerLite projector is capable of remapping input 
resolutions up to 1600
×1200 pixels. Workstations that follow the 
SXGA standard and use the HD15 (standard VGA) connector won’t 
need an adapter cable or any special connection device. If your system 
varies, contact your computer dealer for help in connecting your 
workstation.
Connecting to a DVI Video Source 
The projector’s DVI (Digital Visual Interface) port receives pictures 
directly from your computer in digital format. This lets the projector 
display images of greater clarity than can be achieved using a standard 
analog VGA connection. 
To project images in digital video format, follow these steps:
1. Connect the computer’s DVI cable to the projector’s 
Computer1 
port.
2. To display images properly, make sure the 
Comp1 Input option 
in the projector’s Setting menu is set correctly. See page 56 for 
instructions.
If you want to connect audio for this computer, use the projector’s 
Audio 1 port; if you want to connect a mouse cable (to use the remote 
control as a wireless mouse), use the 
Mouse or USB port.
