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 to the projector in this mode, your connection to 
other wireless networks or devices 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 
(802.11a, 802.11b, or 802.11g) 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. Press the Menu button, then choose Network and press Enter. 
2. Choose 
Network Configuration and press Enter. 
3. Choose 
Wireless LAN and press Enter. 
note
Make sure you’ve installed 
the NS Connection software 
as described on page 199.
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 or 
later. See page 199 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.
