note

Use either ESSID ad hoc

(computer-to-computer) mode

or Access Point (infrastructure)

mode when you set up your

projector. Channel ad hoc

mode is not supported for

Macintosh.

7. Check to make sure AirPort is turned on.

8. Select your projector’s ESSID from the pull-down menu.

If you don’t see the projector’s ESSID, see page 8 for

troubleshooting tips.

See the User’s Guide for

information about the ESSID.

Projecting Wirelessly

Before you begin, make sure you’ve inserted the EPSON wireless

(802.11b) card in the projector and followed the steps beginning on

page 5 to set up your Macintosh.

1. Double-click the EMP NS Connection icon in your Applications

folder.

You see a screen similar to the following:

Select projector

This box indicates

projector status

If the connection is working properly, you see your projector

listed. If you have additional EPSON projectors on the network,

they are also listed.

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

2. Select your projector and click Connect.

note

You can connect to a projector

that is being used by another

person; however, doing so

automatically disconnects the

other user.

If more than one projector is listed, you can select up to four

projectors and connect to them at the same time.

3. If you turned the projector keyword on when setting up the

projector, enter it when prompted and click OK. (It’s the

four-digit number displayed at the bottom of your projector

screen.)

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:

note

Position your pointer over a

button for a description of its

function. For more detailed

descriptions, see the User’s

Guide.

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.

■

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).

note

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.

In Access Point mode, your

projector’s ESSID name and

IP number are shown at the

bottom of the EasyMP

Network Screen.

■

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.
