Checking the Gateway IP Address on Windows
If you’re entering IP addresses manually and need to find out the 
gateway IP address (the IP address of your access point), make sure the 
wireless connection to the access point is currently active, as described 
in the previous section. Then follow these steps:
1. Access your wireless network Properties window. For example, in 
Windows XP you would click 
Start > Control Panel > Network 
and Internet Connections
. Then click the Network 
Connections
 icon. You see a screen similar to this:
2. Right-click the 
Wireless Network Connection icon and select 
Status. 
note
If you cannot identify the 
gateway address using this 
Windows utility, use the 
administrator’s utility 
software that came with 
your access point. 
Right-click and select Status

Making a WPS (Wi-Fi Protected Setup) 
Connection
If you are using a WPS-compatible access point, you can configure the 
settings for the connection between the projector and the access point 
from the projector’s Configuration menu using one of these methods:
■Push Button Method
Press both the 
Enter button on the projector and the button on 
the access point to make the SSID and security settings. This 
method is recommended when the projector and access point are 
close together.
■PIN Code Method
With the PIN code method, you enter an 8-digit code from the 
computer to enable the SSID and security settings. The 
connection between the computer and the access point must have 
already been established. (For connection instructions, refer to the 
manual provided with the access point.) This method lets you 
make the settings without having to press any buttons on the 
projector, and is recommended when the projector is mounted on 
the ceiling.

Using Wireless Security Options 
The projector includes the following network security options which 
you can enable for network projection: 
■Data encryption
WEP and WPA encryption to encode transmitted data.
■Connection limitation (Authentication)
EAP-TLS certificate validation, or LEAP, EAP, or PEAP 
authentication. 
A user’s name and a password are registered in 
advance, which means that only the registered wireless port can 
connect to the network and prevents unauthorized third parties 
from connecting to the network. 
The security functions that can be used with this projector vary 
depending on the connection mode:
■Quick Connection Mode
Encrypted communication
■Advanced Connection Mode
Encrypted communication, WEP, WPA-PSK (TKIP), WPA-PSK 
(AES), EAP-TLS, EAP-TTLS/MD5, EAP-TTLS/MS-CHAPv2, 
PEAP/MS-CHAPv2, PEAP/GTC, LEAP, 
EAP-FAST/MS-CHAPv2, EAP-FAST/GTC 
Make sure the settings you select match the ones used by your 
network; follow the directions from your network administrator. If 
using EAP, you need to make settings at the projector that match the 
authentication server settings. Check with your network administrator 
for details on RADIUS settings.
note
The authentication and 
firewall features are only 
effective when the access 
point for the connection 
destination supports the 
same functions.
