4You can enter the key used for WEP encryption. Enter the key in
single-byte characters following instructions from the network
administrator for the network in which the projector
participates. The type of character and the number that can be
entered differ according to the WEP Encryption and Format
settings.
128Bit - ASCII: Single-byte alphanumeric, 13 characters.
64Bit - ASCII: Single-byte alphanumeric, 5 characters.
128Bit - HEX: 0 to 9 and A to F, 26 characters
64Bit - HEX: 0 to 9 and A to F, 10 characters
Authentication
TypeSet the WEP authentication type.
Open: Uses open system authentication.
Shared: Uses shared key authentication.
PassphraseEnter the passphrase. You can enter at least 8 and up to 63 single-
byte alphanumeric characters. When the passphrase is entered
and the [
] button is pressed, the value is set and displayed as an
asterisk (*).
When using it with EasyMP Network Projection, you do not
need to input the passphrase in the computer if it is the initial
(default) passphrase.
It is recommended to change the passphrase periodically for the
purpose of security. If the network settings are initialized, it
returns to the initial passphrase.

You can enter up to 32 characters on the Configuration menu.
When entering more than 32 characters, use your Web browser
to enter the text.

In Quick mode, the initial passphrase is set.
Type  of  securityWhen  the  supplied  or  optional  wireless  LAN  unit  is  installed  and  being
used  in  Advanced  connection  mode,  it  is  strongly  recommended  that  you
set  security.  Select  one  of  the  following  security  methods.
•WEP
Data  is  encrypted  with  a  code  key  (WEP  key).  This  mechanism  prevents
communication  unless  the  encrypted  keys  for  the  access  point  and  the
projector  match.
•WPA
This  is  an  encryption  standard  that  improves  security  which  is  a  weak
point  of  WEP.  Although  there  are  multiple  kinds  of  WPA  encryption
methods,  this  projector  uses  TKIP  and  AES.
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  using  a  server.  This
projector  supports  the  latter  method,  without  a  server.
