Projecting Over a Network
Once you’ve started EasyMP and set up your projector and computer 
in either Ad Hoc (Quick) mode or Access Point (Advanced) mode, or 
in the optional wired LAN mode, as described on page 84, follow 
these steps to start NS Connection and project over the network. 
1. Make sure you’ve set up your projector (see page 48).
2.Windows: Select 
EMP NS Connection from the Start menu.
Mac OS X: Double-click the 
EMP NS Connection icon in your 
Applications folder.
3. The first time you start NS Connection, you see this dialog box. 
Choose a connection mode and click 
OK.
4. If you see a message asking you to disable the firewall, click 
Yes to 
make an exception for the projector and allow projection. 
note
If you don’t see your network 
adapter’s IP address, allow a 
minute for it to appear. If 
your access point or AirPort 
base station uses DHCP 
(
Distribute IP addresses 
setting is enabled for 
AirPort), sometimes it takes 
a minute for the server to 
pick up the IP address.
Once you’ve selected the IP 
address for your network 
adapter, you won’t see the 
Switch network dialog 
box when you start 
NS Connection. If you want 
to change to a different 
network adapter, click 
Extension on the EMP NS 
Connection dialog box, then 
click 
Switch LAN on the 
extension dialog box. 
						

							74Presenting Through a Wireless NetworkYou see the screen below. (If you have previously started NS 
Connection, this may be the first screen you see.)
If the connection is working properly, you see your projector 
listed. If you have additional Epson projectors on the network, 
they are also listed, along with their status. 
The status is indicated next to each projector’s name.
5. Once the name of your projector appears, select it and click 
Connect. If more than one projector is listed, you can select 
additional ones and connect to them (up to four) at the same 
time. 
If the selected projector is already being used by another person, 
you can still connect to it (unless it is “locked”); doing so 
automatically disconnects the other user. If a projector is locked, 
you won’t be able to connect to it when it is in use.
If you don’t see the projector, follow the suggestions on page 75. 
Select projector
note
If a projector is in use and is 
“locked,” you won’t be able to 
select it.
To lock the projector from 
connection by other users 
while you are connected, click 
the 
Disable interrupt 
connection
 checkbox. 
De-select it to disable the lock 
and allow connection by other 
users. 
If PowerPoint is already 
running when you start the 
projection and you see a 
message that says you need to 
restart PowerPoint, close and 
reopen PowerPoint after 
starting NS Connection.

6. If you set up the projector to prompt you for a keyword before 
connecting, you see a screen like this one: 
Type in the four-digit number displayed on the EasyMP Network 
screen and click 
OK.
7. Once the connection is established, you see your computer’s 
image transmitted to the screen, and a floating control bar on 
your computer desktop:
 
8. If necessary, you can drag the control bar out of the way on your 
screen. 
9. When you’re done with your presentation, click 
Disconnect on 
the control bar. 
Solving Connection Problems
If you don’t see your projector, check the following: 
1. Make sure your wireless signal is strong enough to establish a 
connection. If you have a Mac, check the AirPort icon on the Mac 
menu bar. For Windows, see the documentation for your access 
point or wireless network card or adapter. 
Enter keyword
Windows
Macintosh
note
If none of these suggestions 
work, see the troubleshooting 
information beginning on 
page 157. 
						

							76Presenting Through a Wireless Network2. Make sure you’re trying to connect to the right network. In 
Windows, verify that you’ve enabled your computer’s connection 
to the access point or that your wireless card or adapter is enabled, 
and that its SSID matches the projector’s ESSID. In Mac OS X, 
check the AirPort status menu (click the AirPort icon on your 
menu bar) to make sure AirPort is turned on and the projector’s 
ESSID or your AirPort network is selected. 
3. Make sure you aren’t projecting one of the EasyMP configuration 
screens. (You should see a message that the projector is ready to 
connect.) If you have to exit a configuration screen, restart NS 
Connection.
4. Make sure the ESSID for your projector matches the SSID for 
your wireless card, adapter, or access point. If you have an AirPort 
base station, make sure the projector’s ESSID matches the AirPort 
network name. Remember that the ESSID is case-sensitive.
5. Check the IP address for both your projector and your wireless 
card, adapter, access point, or AirPort base station. The first three 
segments of the IP address should be identical. The last segment 
of the projector’s IP address should be close, but not identical, to 
the last segment of the IP address for your wireless interface, 
access point, or base station.
6. Restart your computer and start NS Connection again.
7. If you still don’t see your projector, follow the instructions in 
“Connecting in Advanced Connection Mode” on page 77 to 
connect to the projector. 
Using the Control Bar
From the control bar, you can access these NS Connection features: 
Displays the Select target projector dialog box.
Stops projection of computer images while connecting 
to the projector. 
The projector projects the computer image.
Pauses projection of computer images. Click again to 
restart projection.
note
The AirPort network name 
may be different than the 
AirPort base station name. 
To check the network name, 
start the AirPort Admin 
utility, select your base 
station, and click 
Configure. Then click 
Show All Settings. The 
network name appears on 
the AirPort tab.

							78Presenting Through a Wireless Network2. Enter the IP address or the projector name for the projector you 
want to connect to, and click 
OK.
The Projector is added to the EMP NS Connection screen.
If the search fails to find a projector with the specified IP address, 
the searching icon turns into a question mark. If this happens, run 
EasyMP on your projector (see page 48) to check the projector’s 
IP address, then repeat this step.
3. Click the projector you want to connect to and click the 
Connect 
button. If more than one projector is listed, you can select 
additional projectors and connect to them at the same time.
4. If you are prompted for a keyword, enter the four-digit number 
displayed on the EasyMP Network screen and click 
OK.
The computer’s image is transmitted to the projector and appears 
on the screen. See page 75 for details about using the floating 
control bar on your computer desktop. 
Enabling Network Security
The projector includes the following network security options which 
you can enable for network projection: 
■Data encryption
Encode and transmit data. Even if data is intercepted, it cannot be 
deciphered. See page 79 to enable encryption. 
■Connection limitation (Authentication)
A user’s name and a password are registered in advance, which 
means that only the registered wireless port can connect to the 
network and prevents unauthorized third parties from connecting to 
the network.

■Firewall
Prevents unauthorized computer access by closing ports that are 
not used.The security functions that can be used with this 
projector vary depending on the connection mode of the wireless 
LAN. Use the firewall function provided with your OS.
The security functions that can be used with this projector vary

Encrypt communications checkbox.
4. Click 
OK.
Enabling Network Security Options
You need to enable network security including WEP, WPA, EAP, 
LEAP, or PEAP, or firewall settings on your network and on the 
projector (see page 67). For network setting details, follow the 
directions from your network administrator.
If using EAP, you need to make settings at the projector that match 
the authentication server settings. Check with your network 
administrator for details on RADIUS settings.
