    *As these models have optional Wi-Fi functionality only, the optional Epson Wireless LAN unit is required - see your projector's User Guide for more information.





In order to set up a connection between your projector and a computer, you must install the Wireless LAN unit in the projector. Also, install EasyMP Network Projection (formerly EMP NS Connection) from the supplied EPSON Projector Software for Meeting & Presentation CD-ROM onto your computer. To use the full EasyMP functions, install all the software from the CD-ROM. See your projector's User Guide and EasyMP Guide for help.

There are two methods of connecting the projector and a computer via a network by using EMP NS Connection; 'Advanced Connection Mode' and 'Quick Connection Mode'.

Advanced Connection Mode is an infrastructure connection, and connects to an existing network system via a network cable. If you install the Wireless LAN unit, in the projector, you can connect to the network via a wireless LAN access point. Advantages of this mode include:

  • From a conference room, you can open and project a file stored on a computer or file server in another room.
  • You can use the Internet.
  • You can monitor and control projector's on a network from the computer.

Quick Connection Mode only runs when you install the optional wireless LAN unit in the projector. It temporarily assigns the projector's SSID to a computer creating an Ad hoc connection, and after disconnecting restores the computer's network settings. If you want to use the Quick Connection Mode, see Related Article "How to set up a quick Ad hoc wireless connection between a computer and the projector" for help.


Prior to setup, make sure that the driver for your computer's wireless LAN card/adapter is installed and it is set up for use. Normally, when a computer has previously been used to connected to a wireless network/device, you do not need to make computer network settings.

  • For Windows: Make network settings for the computer by using the utility software supplied with the wireless LAN adapter, or Windows' own software. For more information, see the Windows documentation or the User's Guide supplied with your wireless LAN adapter.

  • For Macintosh: Set the network port and communication station. For more details on setting the communication status, see the User's Guides for your computer or the AirPort card. Select System Preferences > Network from the Apple menu. The Network settings screen is displayed. In Port Configuration, click into the checkbox beside AirPort so it is ticked. Then click Apply Now. Close the screen.

Please check that you have noted the Network name (SSID), security protocol (e.g. WEP, WPA-PSK (TKIP) etc.), and wireless Security Key.


If you do not have the SSID, security type, or security key please contact your network administrator, Internet provider, or refer to your access point's documentation for assistance.

Setting up the Projector

Before connecting the computer to the projector, you must make some network settings on the projector. These should be the same settings you would use for the infrastructure network you want to connect to (e.g. the network used to connect to the Internet).

You can use the remote control, using the 4-way button to move and the [Enter] button to confirm.

  1. Press the [Power] button on the remote control to turn on the projector. Press the [Menu] button on the remote control. The configuration menu is displayed.

  2. Select Network. The network menu is displayed.


    When Network Protect is set to On in "Password Protect", a message is displayed and the settings cannot be changed. You can make changes after setting "Network Protect" to Off.

  3. Select To Network Configuration. The Network Settings screen in displayed.

  4. Select Basic and set Projector name and Projector keyword.

    • When you later come to connect to the projector via the computer, the name set here is displayed in the projector list by the Epson software. 'EMPxxxxx' (where 'xxxxx' is a specific number) is displayed by default. Change it to a name that is easily remembered. Enter alphanumeric characters e.g. EPSON001.

    • Make a note of the Projector keyword. When set to 'ON', a keyword must be entered when connecting to the network. This can prevent computer from making unscheduled connections and interrupting presentations. Only one computer can connect to one projector at a time.

    • It is not necessary to set 'PJLink Password' or 'Web Control Password'.

  5. Select Wireless LAN from the Network menu. Make the following settings:

    • Connection mode: Set this to Advanced Connection Mode in order to make an Infrastructure network connection.

    • Wireless LAN system: This should be set according to the wireless mode used by your access point/router. The letters 'g', 'b' and 'a' signify a different speed and/or different frequency range.

    • SSID or ESSID: This should match the SSID (name) of your Infrastructure network. This is the same SSID that all wireless devices, including your computer/laptop, uses to connect to the wireless network.


      SSIDs are case sensitive.

    • Antenna level: This displays the electromagnetic wave strength for the wireless LAN.

    • DHCP: This is usually set to On by default. This allows the router/access point to automatically allocate an IP address to the projector, so if you want to manually specify an IP address for the projector you must set it to Off.

    • IP address: The IP address is normally allocated automatically if the access point/router was automatically detected and 'DHCP' is On. If the access point wasn't added automatically or 'DHCP' is Off, you will need to manually enter an available IP address to the projector.

    • Subnet Mask: This should match the Subnet Mask of the access point/router.

    • You do not normally need to specify the 'Gateway address' and 'DNS server (primary)/DNS server (secondary)' settings.

  6. Next, scroll to the Security menu. Select the security mode used by your wireless network. Select 'No' if wireless devices are not required to enter a passkey to connect to the network (unsecured network). If a passkey if required to connect wireless devices to the network, you must select the security mode. The most common are WEP, WPA-PSK (TKIP), WPA-PSK (AES), WPA2-PSK (TKIP), or WPA2-PSK (AES). Other security protocols are also available for selection.

  7. If you select WEP or WPA, you will need to enter some further details including the Encryption Key (WEP) or PSK (Passkey, for WPA). Enter the key or password of your access point/wireless network. This is the same passkey used by other wireless devices.

    Screen when WEP is selected: Screen when WPA is selected:

    Our projectors support the 802.1x standard (with RADIUS server for authentication). Protocols supported are LEAP, EAP-TLS, EAP-TTLS/MD5, EAP-TTLS/MS-CHAPv2, PEAP/MS-CHAPv2, PEAP/GTC and the Cisco protocols LEAP and EAP-Fast (MS-CHAPV2 or GTC).
    If you select one of these protocols, you may need to add a certificate inside the projector (using the USB key) and/or enter the user name and password for your projector:

  8. Scroll down to the Setup complete tab. Select Yes to save the network settings and return to the configuration menu.

  9. Press the [Menu], [EasyMP] or [LAN] button on the remote control. The configuration menu closes. While the configuration menu is displayed, network connection becomes invalid.

Operating the Computer

In the following explanations, unless otherwise noted, Windows screen images are used. You see the same screens even when using a Macintosh computer.  Please also note that EMP NS Connection is now known as EasyMP Network Projection.

  1. Start EasyMP Network Projection.

    • Windows: Select Start > Programs (or All Programs) > EPSON Projector > EasyMP Network Projection.

    • Mac OS X: Double-click the Applications folder of the hard drive volume in which EasyMP Network Projection is installed, and then double-click the EasyMP Network Projection icon.

  2. The EasyMP Network Projection window is displayed. Select Advanced Connection Mode and then click OK. If preferred, tick the box beside 'Set the selected Connection Mode as the default mode for future connections.'. Advanced Connection Mode will be set as the default and this window will not shown again and therefore you will not have the option to choose a mode next time.

    • If the following screen is displayed during startup, click the Yes button.

      When you click Yes, a firewall exception is created for EasyMP Network Projection and it can then be used.

    • If EasyMP Network Projection is started while PowerPoint is running, the message "If PowerPoint is not restarted you may not be able to execute a slide show." is displayed. In this case you need to close PowerPoint and reopen it after starting EasyMP Network Projection.

  3. The projector search results are displayed. Select the projector you want to connect to, and then click Connect. If the projector you want to connect to is not displayed in the search results, click the Automatic search button. The search takes about 30 seconds.

  4. If you have set a keyword on the projector, check the keyword displayed on the EasyMP standby screen, and enter the projector's keyword.

You can now project images. Please refer to your User's Guide and EasyMP Guide for information on projecting images, movies and PowerPoint Presentations, using EasyMP SlideMaker2, Multi-Screen Display, and other EasyMP features.
