connect the projector to a Windows computer wirelessly without any 
configuration.
First, make sure you have installed the wireless module as described on 
page 89 and turned on the projector.

TypeA (flat)  USB 
port.
2. When you see a projected message that the network information 
update is complete, remove the USB key.
3. Connect the USB key to a USB port on your computer or 
notebook.

Account Control screen, click 
Allow.
4. Follow the instructions on the screen to install the Quick Wireless 
Connection driver. 
If you see a Windows Firewall message, click 
Yes to disable the 
firewall.
After a few moments, your computer image will be displayed 
through the projector. If not, try restarting your computer.
5. When you’re done with your presentation, remove the USB key. 
You may need to restart your computer to reactivate your wireless 
interface.

Configuring a Wireless Connection
After you install the optional wireless LAN 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. 
■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. 
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 
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, Vista, 
or Windows 7. Your Mac 
must be running Mac OS X 
10.3 to 10.6. 
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.
