							52Presenting Through a Wireless Network
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 or 802.11b) network card or adapter, or a Macintosh 
with an AirPort
® or AirPort Extreme card. 
■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 or 802.11b) 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. 
Using Ad Hoc Mode 
To use Ad Hoc (computer-to-computer) mode, adjust your projector 
and wireless card or adapter settings as described in this section. 
Configuring the Projector
1. Switch the projector to EasyMP mode and insert the Epson 
802.11G/B card (see page 50). You see this screen:
note
Make sure you’ve installed 
the NS Connection software 
as described on page 169.
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 98, Me, 2000, or 
XP. Your Macintosh must 
be running OS X 10.2.4 or 
later. See page 169 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.
