folder.

projector. Channel ad hoc
mode is not supported for

See the User’s Guide for
information about the ESSID.

You see a screen similar to the following:
If the connection is working properly, you see your projector
listed. If you have additional EPSON projectors on the network,
they are also listed.

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

You can connect to a projector
that is being used by another
person; however, doing so
automatically disconnects the
other user.
If you assign a keyword to the
projector, only people in the
same room as the projector can
connect to it, so you won’t be
disconnected during a
presentation.

Once the connection is established, your computer’s desktop and
a floating control bar are projected:
4. If necessary, drag the control bar out of the way, or minimize it.
5. When done with your presentation, click Disconnect on the
control bar.
Solving Connection Problems
If you don’t see your projector in the EMP NS Connection window,
try the following:
■Make sure the EPSON 802.11b card is inserted in the projector;
see the User’s Guide for instructions. If you have to insert the card,
restart EMP NS Connection, or the program will not be able to
detect the projector.
■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
EMP NS Connection.
■Click the AirPort icon on the Application bar at the top of your
Macintosh desktop to make sure you’re trying to connect to the
right network. The projector’s ESSID should be displayed and
selected.
note
Position your pointer over a
button for a description of its
function. For more detailed
descriptions, see the User’s
Guide.

■Make sure AirPort is turned on. Click the AirPort icon on the
Application bar and select AirPort: On if necessary. If you don’t
see the AirPort icon, follow the instructions beginning on page 5
to enable AirPort.
■If possible, move your projector, Macintosh, and base station (if
you’re using one) closer together.
■If you’re using Access Point (infrastructure) mode and you’re
connecting to the wrong network, you may be experiencing signal
interference from another network. Open the Applications
folder on your hard drive, then double-click the Utilities folder.
Double-click AirPort Admin Utility. If you don’t see your base
station listed, reset the base station (see the instructions that came
with your base station).
If your base station is listed, check its name and IP address. Your
projector should have the same ESSID name, and the first three
segments of the projector’s IP address should be identical to the
first three segments of the base station’s IP address. The last
segment of the projector’s IP address should be close, but not
identical to the last segment of the base station’s IP address. In
addition, the projector’s gateway address should be identical to
the base station’s IP address. See the User’s Guide for instructions
on setting up the projector in Access Point mode.
■If you’re unable to connect to the projector, use IP Connect
Mode to connect manually. See the User’s Guide for instructions.
■Check the Network Configuration tab for your AirPort base
station. If you set up your projector to connect in DHCP mode,
Distribute IP Addresses and Start a Single IP Address should
both be on. See your AirPort documentation for details about
configuring your base station.
note
In Access Point mode, your
projector’s ESSID name and
IP number are shown at the
bottom of the EasyMP
Network Screen.
