Connecting a Component Video Source
1. Locate a component video cable (one may be included with your 
video equipment). 
Look at the connectors at one end of the cable. If they are 
bayonet-style (BNC) connectors, continue on to the next step. If 
they are RCA-style connectors, you’ll need to attach commercially 
available BNC adapters to plug the cable into your projector.  
2. Connect the cable to your player and the cable (with the adapters) 
to the 
BNC connectors on the projector. Match the Y/Cb/Cr (or 
Y/Pb/Pr) connectors on your player to the corresponding 
connectors on the projector.
3. If you want to play sound through the projector, see page 65 for 
instructions on connecting an audio cable.
4. If you don’t need to make any other connections, see Chapter 1 
for instructions on turning on the projector and adjusting the 
image. Once the projector is turned on, do the following:
■Enter the projector’s Setting menu, then change the BNC 
Input setting to 
YCbCr or YPbPr, as needed (see page 137).
■After exiting the menu system, press the remote control’s 
BNC button or repeatedly press the projector’s Video/BNC 
button to select 
BNC as the image source.

Playing Sound Through the Projector
You can play sound through the projector’s speaker system, or you can 
attach an external speaker system. (Attaching speakers to the projector 
instead of directly to the audio source lets you use the projector’s 
remote control to adjust the sound.)
Connecting Audio Equipment to the Projector
To play sound through the projector, follow these steps:
1. Locate the appropriate audio cable (two types are included with 
the projector). Which cable you use depends on how your 
equipment is connected:
■If you have a computer connected to the Computer or DVI 
port, use the stereo mini-jack cable.
■If you have video equipment connected to the Video or 
S-Video port, or to the BNC ports, use the RCA-style audio 
cable.
2. Connect the audio cable to the jack corresponding to the 
connected video source. 
  
3. Connect the other end of the cable to the audio-output connector 
on your computer or video equipment.

real-time, any changes you make on your PC or laptop are 
automatically mirrored on the screen. 
You’ll find instructions in this chapter on:
■Starting EasyMP
■Connecting to the projector in Ad Hoc mode or Access Point 
(infrastructure) mode
■Projecting wirelessly
■Using projector groups
■Removing the wireless 802.11b card
Before starting, make sure you’ve installed EMP NS Connection as 
described in Appendix A for each computer you want to be able to 
connect to the projector. Then follow the steps in this chapter to start 
EasyMP, configure your projector and computer, and run EMP 
NS Connection.

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 
(802.11b) network card or adapter, or a Macintosh with an 
AirPort
® or AirPort Extreme card. 
■Access Point mode (infrastructure mode) lets multiple users 
access the projector at the same time and easily trade off control 
over the projector. To use Access Point mode, you need a wireless 
(802.11b) access point, or an AirPort (or AirPort Extreme) 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 
In order to use Ad Hoc (computer-to-computer) mode, first adjust 
your projector and wireless card or adapter settings as described in this 
section. 
Configuring the Projector
