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. 
2. 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 SSID (or ESSID). On a 
Macintosh, check the AirPort status menu (click the AirPort icon 
on your menu bar) to make sure AirPort is turned on and the 
projector’s SSID 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 SSID 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 SSID matches the AirPort 
network name. Remember that the SSID 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 94 to 
connect to the projector. 
note
If none of these suggestions 
work, see the troubleshooting 
information beginning on 
page 191.
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.

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 
depending on the connection mode:
■Quick Connection Mode

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 84). 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.

Multi-screen Projection
When using Multi-screen display, you can set each projector to 
display a section of the screen or image, to create a single image 
spanning a large area. Make sure the projectors are at least 3.6 feet 
(1.1 meters) apart to avoid overheating.
Multi-screen projection is not supported in Windows Vista. 
Here are some examples: 
note
For a Mac, you have to 
connect a monitor to the 
computer and use the 
multi-screen display 
function. For Windows, 
even if a monitor is not 
connected, you can set a 
virtual display by installing 
the virtual display driver in 
EMP NS Connection. See 
page 201.
For Windows, when the real 
monitor is connected as a 
secondary monitor, the 
image for that screen cannot 
be projected.
You can adjust each 
projector’s color to match the 
images as closely as possible. 
See page 151.
