Configuring a Wireless Connection
If you have installed the optional wireless LAN module (G5150NL 
and G5350NL only), 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, you cannot connect to 
other wireless networks or devices; 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 in the EasyMP 
Operation Guide.
To connect to the projector 
over a wireless network, your 
computer must be running 
Windows 2000, XP, or 
Vista. Your Mac
® must be 
running Mac OS X 10.3 or 
later. See the EasyMP 
Operation Guide for 
complete system 
requirements for projecting 
wirelessly.
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.

Setting Up Your Mac for Ad Hoc Mode
Your AirPort software is automatically configured to allow your Mac 
to detect both computer-to-computer (Ad Hoc) and Access Point 
networks. 
Typically, you only need to select your projector’s ESSID from the 
AirPort status menu on the Mac menu bar. If you’re having problems 
detecting the projector, follow these steps:
1. From the Apple pull-down menu, select 
System Preferences. 
2. Double-click the

wireless network, use Access 
Point mode, as described on 
page 69. Also, make sure 
you reconnect to your 
original wireless network 
when you are done using the 
projector.
