Configuring a Wireless Connection
After you install the optional Wireless 802.11g/b/a Module, you can 
use the EasyMP Network Projection software 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. 
note
You can interrupt projection 
even when a keyword is 
used. Press the 
Esc button 
on the remote control and 
select the Close option.
note
Make sure you’ve installed 
the EasyMP Network 
Projection software as 
described in the EasyMP 
Network Projection 
Operation Guide.
To connect to the projector 
over a wireless network, your 
computer must be running 
Windows 7, Windows 
Vista, Windows XP, or 
Windows 2000. Your Mac 
must be running Mac OS X 
10.3 to 10.6. 
Access Point mode 
(infrastructure mode) is 
required to achieve transfer 
speeds up to 54MB/sec on an 
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.  
						

							82Using the Projector on a Network
■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.
Configuring the Projector
1. Press the Menu button, then choose Network and press Enter.
2. Choose 
Network Configuration and press Enter.
3. Choose 
Wireless LAN and press Enter. You see this screen:
4. Make sure Wireless LAN Power is set to 
On. You can turn it off 
to prevent unauthorized access. 
5. Select one of the following connection modes:
■Quick mode lets you easily connect one computer to the 
projector at a time. You can also select this setting when 
you’re using the optional Epson Quick Wireless Connection 
USB key.
■Advanced mode lets multiple computers access the projector 
at the same time and easily trade off control of the projector. 
This method requires a wireless network access point or an 
AirPort Extreme (or AirPort) base station.
