Setting the Encryption and Authentication Methods
for Wireless LAN Access Point Mode
You can select one encryption/authentication method from the following
available options when using wireless LAN access point mode and running
Network Screen.
• WEP
This uses an encryption key (WEP key) to encode the data.
It works so that if the encryption keys at the access point and the
projector are not identical to each other, data cannot be transmitted.
• WPA
This is an encryption standard that improves security which is a weak
point of WEP. Several different types of encryption method can be used
with WPA, and this projector uses TKIPg. TKIP uses PSK to
automatically update the encryption key at a regular fixed interval, which
makes it harder to break compared to WEP which uses a constant
encryption key.
WPA also includes user authentication functions. WPA authentication
provides two methods: using an authentication server, or authenticating
between a computer and an access point without the server. The EasyMP
supports the latter method (without the server).
• LEAP
This is an authentication method that uses the CCXg wireless LAN
security technology developed by Cisco Systems which combines a
unique user authorisation function and an encryption function.
You can't use LEAP without an authentication serverg (RADIUS
serverg). LEAP uses passwords for authentication without using
electronic signatures.
PROCEDURE
Insert a wireless LAN card into the card slot of the
projector.
Set the projector to EasyMP standby screen.

EasyMP Network Setup Guide
•
Follow the instructions from the network administrator for the
network you are using when making these settings.
•
If using LEAP, you need to make settings at the projector which
match the authentication server settings. Check with your network
administrator for details on RADIUS server settings.
•
You can use an Internet web browser to access a browser page for
setting and controlling the projector, and you can make the network
settings on that browser page (EasyWeb). Because you can use the
keyboard to enter setting values with EasyWeb, it is useful to use in
order to avoid the inconvenience of entering values using the remote
control. sp.60
