Connecting External Speakers
When you use EasyMP, you can output the sound to external speakers 
with a built-in amplifier. 
To connect speakers to the projector, follow these steps: 
1. If your speakers have a stereo mini-jack connector, connect it to 
the 
Audio port on the projector. If your speakers have two RCA 
stereo jacks, use the audio adapter included with the projector.
 
2. Set the EasyMP Audio Out option in the projector’s Settings 
menu to 
External. See page 105 for instructions. 
The projector’s internal speaker system is disabled while sound is 
output to external speakers.

Setting Up Network 
Projection
This chapter tells you how to prepare to send images to your 
projector through a wireless or wired network. 
Using Quick Wireless Connection or EMP NS Connection, you can 
project images shown on your computer screen—including text, 
graphics, and video—directly to your audience. See the EasyMP 
Operation Guide for information on features and use.
If you have Windows Vista, you can also use the Network Projector 
feature to communicate with your network-connected projector.
You’ll find instructions in this chapter on:
■Using Quick Wireless Connection
■Configuring projector and network settings
■Using wireless security options
■Removing the wireless 802.11a/b/g module
■Connecting the projector to a wired LAN
■Sending e-mail alerts and monitoring the projector
■Using Windows Vista Network Projector
Before starting, make sure you’ve installed the wireless module, as 
described on the Quick Setup sheet, or the optional Ethernet unit 
(see page 90). Then follow the steps in this chapter to use Quick 
Wireless Connection (Windows only) or configure your projector and 
network. Finally, see the EasyMP Operation Guide for instructions on 
installing the EMP NS Connection software. The EasyMP Operation 
Guide also contains instructions on using the software to project over 
the network.

Using Quick Wireless Connection
Using the USB key that came with your projector, you can quickly 
connect the projector to a Windows computer without any 
configuration.
First, make sure you have installed the wireless module and turned on 
the projector as described on the Quick Setup sheet.
1. Connect the USB key to the projector’s   
Type A (flat) USB 
port.
2. When you see a projected message that the network information 
update is complete, remove the USB key.
3. Connect the USB key to a USB port on your computer or 
notebook.
In Windows Vista, if you see the AutoPlay window, select 
Run LaunchU3.exe. When you see the User Account Control 
screen, click 
Allow.
4. When you see a license agreement, click 
Agree to install the 
Quick Wireless Connection driver. 
If you see a Windows Firewall message, click 
Yes to disable the 
firewall.
After a few minutes, your computer image will be displayed 
through the projector. If not, try restarting your computer.
5. When you’re done with your presentation, remove the USB key. 
You may need to restart your computer to reactivate your wireless 
interface.
note
The USB key is stored in a 
small pouch inside the 
carrying case. Do not 
attempt to write to the key 
or use it as a flash memory 
drive. To replace a lost or 
missing key, contact Epson 
(see page 12).
note
The Quick Wireless 
Connection utility will 
disable any other wireless 
sessions and adapter 
programs. Make sure you 
leave the USB key in your 
computer for your entire 
Quick Wireless Connection 
session. Follow the 
instructions on this page to 
remove the USB key when 
you are finished with the 
session.

Configuring the Connection
You can use NS Connection to connect to the projector and send 
images wirelessly in two modes: Ad Hoc mode or Access Point mode. 
■Ad Hoc mode (computer-to-computer mode) lets you connect 
just one computer to the projector at a time; it’s easy to set up, 
and the only equipment you need is a computer with a wireless 
(802.11g, 802.11b, or 802.11a) network card or adapter, or a 
Macintosh
® with an AirPort® or AirPort Extreme card. When 
you connect with this mode, any connection to other wireless 
networks is broken; you can connect to the projector only. 
■Access Point mode (infrastructure mode) lets multiple computers 
access the projector at the same time and easily trade off control 
over the projector. To use Access Point mode, you need a wireless 
(802.11g, 802.11b, or 802.11a) access point or an AirPort 
Extreme (or AirPort) base station, and one or more computers 
with wireless network cards or adapters. 
Follow the instructions below for the mode you want to use. 
note
Make sure you’ve installed 
the NS Connection software 
as described in the EasyMP 
Operation Guide.
To connect to the projector 
o v e r  a  w i r e l e s s  n e t w o r k ,  y o u r  
computer must be running 
Windows 2000, XP, or 
Vista. Your Mac must be 
running Mac OS X 10.3 to 
10.5. See the EasyMP 
Operation Guide for 
complete system 
requirements for projecting 
wirelessly.
Access Point mode 
(infrastructure mode) is 
required to achieve transfer 
s p e e d s  u p  t o  5 4 M B / s e c  o n  a n  
802.11g network. Ad Hoc 
mode (computer-to-
computer mode) limits 
network connections to 
11MB/sec. This is a 
standard specification of 
802.11g networking.

Note that the SSID is case-sensitive (if you enter the name in 
uppercase on the projector, you must type it the same way on the 
computer connecting to the projector). 
7. If you want to prevent the SSID from being displayed on the 
standby screen, set the 
SSID Display option to Off.
8. To prevent the IP address from appearing on the standby screen, 
set the
