Presenting Through a 
Wireless Network
This chapter tells you how to send pictures to the projector through 
a wireless network. Using EMP NS Connection, you can project 
images shown on your computer screen—including text and 
graphics—directly to your audience. Because images are displayed in 
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
■Running the EMP NS Connection software
Before starting, make sure you’ve installed EMP NS Connection as 
described in Appendix A or on the Quick Setup sheet 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. 
note
For international users, 
please observe any local 
regulations concerning the 
use of wireless technology.

Starting EasyMP
Before connecting to the projector, you have to switch it to EasyMP 
mode. Follow these steps:
1. Turn on the projector, as described on page 10.
2. Select 
EasyMP as the source, using either the Comp/EasyMP 
button on the remote control or the 
Source button on the 
projector (see page 11).
3. Insert the EPSON 802.11b card (with the blue label facing up).
Once the card is inserted, you see one of these screens, depending 
on the currently selected mode:
4. If you’ve already set up your computer and projector for the mode 
you want to use—Ad Hoc mode or Access Point mode (also 
called infrastructure mode)—skip to “Running NS Connection” 
on page 42. 
Otherwise, continue on to the following section. 
note
Only the EPSON 802.11b 
card is guaranteed to work. 
Other brands may not be

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 lets you connect just one PC or laptop 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. 
■Access Point mode (or “infrastructure” mode) is more complex to 
set up, but 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 and one or more 
computers with built-in wireless network cards. 
Follow the correct instructions below for the mode you want to use. 
Using Ad Hoc Mode 
In order to use Ad Hoc mode, first adjust your projector and network 
card settings as described in this section. 
Configuring the Projector
To configure the projector for Ad Hoc mode, make sure you’ve 
switched it to EasyMP and inserted the network card (see page 28). 
Then follow these steps:
1. On the EasyMP Network Screen, the 
Config button is already 
highlighted as shown below. 
2. To select 
Config, press the Enter button on the remote control.
note
Make sure you’ve installed 
the NS Connection software 
as described in Appendix A 
or the Quick Setup sheet.

arrows to select individual characters, and use the right arrow to 
move to the next character position. When done typing the new 
name, press 
Enter.
5. To enable your computer to find the projector on the network, 
select the appropriate 
Ad hoc mode settings:
■Select ESSID ad hoc if your network card supports an SSID 
or ESSID identifier (see page 33). Then enter a name (for 
example, “CONF ROOM”) in the 
ESSID text box and press 
Enter. Note that the ESSID is case-sensitive (if you enter the 
name in upper-case on the projector, you must type it the 
same way on the computer connecting to the projector). 
■Select Channel ad hoc if your network card supports using 
channels instead of ESSID names to identify devices on the 
network. Then select a channel number in the 
Channel text 
box and press 
Enter. 
6. If you want to set up a security keyword so that only people who 
are in the same room as the projector can access it, turn 
Projector 
keyword
 on. Then when you want to connect to the projector, it 
displays a randomized four-digit number or “keyword” on the 
screen. When prompted by NS Connection, you can enter the 
keyword on your computer to connect (see page 43). 
7. When done making these settings, highlight the 
OK button at the 
top of the screen (you can either use the arrow buttons on the 
remote control or press 
ESC to highlight it), then press Enter. 
Highlight the 
OK button again and press Enter to return to the 
main EasyMP Network Screen. 
Configuring the Network Settings on Your Laptop 
or PC
Before connecting to the projector, you need to make sure the settings 
for your laptop’s or PC’s network card match the settings you entered 
for the projector. 
1. Access your wireless network Properties window. For example, in 
Windows XP you would click 
Start > Control Panel > Network 
and Internet Connections
. Then click the Network 
Connections
 icon.

settings may be described differently from those listed here.)
■Set the network type to 802.11 Ad Hoc.
■Set the SSID to match the name you assigned to the 
projector’s ESSID—for example, 
CONF ROOM. (If your 
network card uses channel mode instead, set the correct 
channel, 1 to 11, so it matches that of the projector.)
■Make sure encryption is Disabled. 
6. Click the 
General tab and make sure that the network card or 
wireless network device is enabled. 
7. When done making the settings, click 
OK to close the network 
card’s properties dialog box. 
Now you’re ready to connect to the projector. See “Running NS 
Connection” on page 42.
