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 154, follow 
these steps to start NS Connection and project wirelessly over the 
network: 
1. Make sure you’ve set up your projector (see page 58).
2.Windows: Select 
Start > Programs or All Programs > 
EPSON Projector > EMP NS Connection
.
Macintosh: 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. 
In Windows Vista, click 
Continue when the User Account 
Control screen appears. 
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. 
						

							90Presenting 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 92. 
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 Microsoft 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.
