Using the Projector on a Network71
Configuring the Connection
You can use EasyMP Network Projection to connect to the projector 
and send images wirelessly in two modes: Ad Hoc mode or Access 
Point mode (PowerLite 85+/825+/826W+ only).
■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. 
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. 
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, Vista, XP, or 
2000 (SP4). 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.

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). 
8. If you want to prevent the SSID from being displayed on the  standby screen, set the 
SSID Display option to Off.
9. To prevent the IP address from appearing on the standby screen,  set the 
IP Address Display setting to Off.
