• For information about the Wireless Connection 3 procedure to simultaneously project images from multiple computers and to perform other operations, see “Wireless LAN Connection Operations” (page 25). C 16 7. To close Wireless Connection 3, click the close button in the upper right corner of its window. • If the message “The projector is still projecting. OK to exit?” appears, click [OK]. • This closes the Wireless Connection 3 window and returns the projected image to the Wireless standby screen. Note • When a computer finds multiple projectors that can be connected to, a Projector List dialog box appears after the “Connecting” message. When this happens, select the SSID of the projector to be connected to by clicking it, and then click [OK]. • To re-establish a wireless LAN connection with a projector configured with a default SSID after a previous connection was terminated, perform the above procedure from the beginning. The login number is updated to a new one whenever the projector is re-started. This means you will need to check the login number each time you connect. • Configuring security settings eliminates the need to enter a login code when establishing a wireless LAN connection between the projector and a computer. Once you enter a character string called a “passphrase” (or WEP key) the first time you connect, you will not need to re-enter it from the next time you connect from the same computer. Establishing a Wireless LAN Connection from Multiple Computers After establishing a wireless LAN connection between the projector and one computer, you can establish connections with a second, third, and even fourth computer. The procedure for establishing a connection with the second and subsequent computers is the same as the procedure from step 3 under “To use a default SSID to connect a computer to the projector via wireless LAN” (page 15). Note, however, that the display contents of subsequently connected computers will not appear automatically if the display contents of the first computer are being projected. To project the screen contents of subsequently connected computers, click the button on the Wireless Connection 3 window. For information about the Wireless Connection 3 procedure to simultaneously project images from multiple computers and to perform other operations, see “Wireless LAN Connection Operations” (page 25). 17 Configuring Security Settings for a Wireless LAN Connection Configuring Security Settings for a Wireless LAN Connection Configuring security settings prevents unauthorized access to a computer or projector over the wireless LAN. Settings are configured with the projector’s System Admin page, which can be accessed with a computer’s web browser. This section explains only the security settings of the System Admin page. For details about other System Admin page operations, see “System Admin Page Operations and Settings” (page 33). Security Setting Flow To configure security settings, you first need to establish a wireless LAN connection between the projector and computer. For information about establishing a connection between a projector that does not have security settings configured and computer, see “Using a Default SSID to Connect a Computer to the Projector via Wireless LAN” (page 15). Establishing a wireless LAN connection between the projector and computer On the computer, log in to the projector’s System Admin page. On the System Admin page, select “Setup” and then “Wireless Setup”, and configure the following settings. • Assign a new SSID to the projector. • Select a security protocol (WPA-PSK, WPA2-PSK, or WEP). • Enter the passphrase (or WEP key). Apply (register) the above settings to the projector. (At this time the wireless LAN connection between the projector and computer will be terminated.) Click the Wireless Connection 3 [Reconnect] button. On the dialog box that appears, enter the passphrase (or WEP key). This will establish a wireless LAN connection provided with security in accordance with the selected protocol. 18 Configuring Security Settings This section explains the procedure for logging in to the projector’s System Admin page from a computer and configuring wireless LAN connection security settings. To log in to the projector’s System Admin page 1. Perform the procedure under “To use a default SSID to connect a computer to the projector via wireless LAN” (page 15) up to step 6 to establish a wireless LAN connection between the projector and computer. 2. On a Wireless Connection 3 window, click the function menu button and then click [Admin Screen] on the menu that appears. Function menu button • This starts up the computer’s web browser and displays the projector’s top System Admin page. 3. Click “System Admin”.
