network, go to “Projecting Wirelessly” on page 15. 
Otherwise, continue with the next section.
Configuring the Connection
You must configure both the projector and your computer’s 
network settings to project wirelessly.
You can configure the projector for either of the following 
modes:
Ad Hoc mode: Lets you connect just one computer at a time; 
you need a computer with a wireless (802.11g or 802.11b) 
network card or adapter, or a Macintosh with an AirPort
® or 
AirPort Extreme card.
Access Point mode: Lets multiple computers access the 
projector, or trade off control of the projector; you need a 
wireless (802.11g or 802.11b) access point or an AirPort (or 
AirPort Extreme) base station, and one or more computers 
with wireless network cards or adapters.
1. Switch the projector to EasyMP mode and insert the Epson 
802.11G/B card.
2. When you see the EasyMP screen, press the 
Enter button 
on the remote control to select 
Config.

Configuring the Network Settings for Windows
Before connecting to the projector wirelessly, make sure your 
computer is configured correctly. Also, make sure that the 
Internet Connection Firewall is disabled. (See your Windows 
online help system for details.)
Note:
Depending on your computer’s wireless network adapter card, 
the dialog boxes you see may be different than those shown in 
this section.
1. Access your wireless network Properties window. For 
example, in Windows XP click 
Start > Control Panel > 
Network and Internet Connections
. Then double-click 
the 
Network Connections icon. You see a screen similar to 
this:
2. Right-click the 
Wireless Network Connection icon and 
select Properties. You see a screen like this:
ESSIDAd Hoc: Enter an ESSID in the ESSID 
textbox.
Access Point: Enter an ESSID, which 
is the SSID name of your access point 
or the name of your AirPort network. 
(The name of your AirPort network 
may be different from that of your 
AirPort base station; select your base 
station in the AirPort Admin utility and 
click Configure to check the name of 
your network.) 
Note that the ESSID is case-sensitive.
Password for WEB 
controlIf you want to create a password for 
an internal web page, you can enter 
up to 8 alphanumeric characters.
Projector keyword Turn this option on if you want to set 
up a security keyword so that only

displays a four-digit randomized 
keyword on the screen that you need 
to enter when prompted.
DHCP (Access Point

addresses automatically, turn this 
option on. Otherwise, turn it off and 
assign an IP address, subnet mask, 
and gateway address manually.
IP address (Access 
Point mode only)Enter the IP address you want to 
assign the projector. It must be 
formatted like other addresses on the 
network; usually the first three 
sections match the access point’s IP 
address. The last section should be 
unique.

(Access Point mode 
only)Enter a subnet mask formatted like 
other subnet masks on your network.
Gateway address 
(Access Point mode 
only)Enter the IP address that was assigned 
to your access point or AirPort base 
station when it was set up. If you don’t 
know the address, see “Checking the 
Gateway (Access Point’s) IP Address” 
on page 14.

8/04 Epson PowerLite 745c Projector - 15 Projecting Wirelessly
Once you’ve started EasyMP and set up your projector and 
computer in either Ad Hoc mode or Access Point mode, 
follow these steps to start NS Connection and project 
wirelessly.
Note: 
You must have installed EMP NS Connection from your projector 
CD-ROM. See the User’s Guide for installation instructions.
1. Make sure you’ve inserted the Epson 802.11G/B card in 
the projector’s card slot (see page 10). 
2.Windows: Select 
EMP NS Connection from the Windows 
Start menu.
Macintosh OS X: Double-click the 
EMP NS Connection 
icon in your Applications folder.
The first time you start NS Connection, you see a dialog 
box asking you to select your network. Select the name 
for your computer’s wireless network adapter card and 
click 
OK.
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, sometimes it takes a minute for the server 
to pick up the IP address.
You see the screen below. (If you have previously started 
NS Connection, this is the first screen you see.)Note: 
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.
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 color of the status icon next to each projector’s name 
indicates its status:
❏Gray: the projector is not connected
❏Orange: the projector is connected to another 
computer
❏Green: the projector is connected to your computer
3. If you don’t see your projector, check the following:
❏Make sure your wireless signal is strong enough to 
establish a connection. If you have a Macintosh, check 
the AirPort icon on the Macintosh menu bar. For 
Windows, see the documentation for your access point 
or computer network card.
❏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 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 ESSID or your AirPort network is selected. 
Remember that the ESSID is case-sensitive.
❏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 
the configuration screen, restart NS Connection.
❏Check the IP address for both your projector and your 
wireless card, adapter, access point, or AirPort base 
station. The first three sections of the IP address should 
be identical. The last section of the projector’s IP 
address should be close, but not identical, to the last 
section of the IP address for your wireless interface, 
access point, or base station.
❏Restart your computer and start NS Connection again.
❏If you still don’t see your projector and you are using 
Access Point mode, follow the instructions in 
“Connecting in IP Connect Mode” on page 16 to 
connect to the projector manually.
❏Make sure you have disabled any firewall software.
