Note
• The wireless LAN settings take effect the moment you closes the menu.
● Details on individual items
• [Mode]
Your projector is set to Ad hoc in the factory. Change the setting if you want to use the
projector in Infrastructure mode.
• [Channel]
Usually, you do not have to set this item. If a network group having the same SSID
already exists in the projector’s coverage, the channel is changed automatically to the
channel of that network group.
Note 1: If a set channel is in bad connections for wireless connection, try the other
channels to avoid the effects of radio waves to select the one in possibly the
best communication conditions.
Note 2: To communicate in Ad hoc mode with a computer that cannot change the
channel, start up the projector before the computer.
• [SSID]
This is an ID code for connecting to specific individuals over a wireless LAN. This may
also be called “Network group” or “Network name”. Please read the following carefully.
Note 1: The SSID is set to DPJ when shipped from the factory. If you leave this setting
as it is, security may be compromised due to access by a third party using the
“Wireless Utility” within the projector’s possible communication area. Before
using the projector, therefore, be sure to set SSID to a character string different
from the default.
Note 2: When you use the Ad hoc communication mode, if there is a similar SSID
network group (for example DPJ, DPJ1, DPJ2, etc.) in the possible communi-
cation area, it is possible that your projector name will not be displayed in the
Wireless Utility projector list column. If this is the case, set SSID to a com-
pletely different character string.
• [Encryption]
Enable or disable encryption for security purposes.
Note: Encryption is factory-set to Off. If you use the projector with this setting left
unchanged, security may be compromised due to access by a third party using
the Wireless Utility within the projector’s coverage. Before using the projector,
therefore, be sure to set Encryption to On.
• [Key]
When you have set Encryption to On, the encryption key must be set. For use at an
encryption level of 64-bit, specify a string of 5 arbitrary characters or a string of ten
characters in hexadecimal notation. For use at the 128-bit level, specify a string of 13
arbitrary characters or a string of 26 characters in hexadecimal notation.
Note: Alphabetic characters (A to F, a to f) used in hexadecimal notation are case
insensitive; the uppercase characters and their lowercase equivalents are
handled to be identical.
The higher the number of bits, the stronger the encryption, and hence the harder it will
be for a third party to decipher your communications. However, setting higher encryp-
tion levels may slow down communication speed. To set the highest security level,
specify a 128-bit encryption key. For higher security, avoid using a word found in a
dictionary and change the key sometimes.
Set the following item if you have set the communication mode to Infrastructure.
• [DHCP]
If you set DHCP to Use, the IP address of the projector is assigned automatically by the
DHCP server. If your network environment does not assign IP addresses automatically,
set DHCP to Not use, then set the following item TCP/IP manually.
• [TCP/IP]
If you have set DHCP to Not use, ask the network administrator to check for the
following items, then perform the TCP/IP settings manually.
• IP address
An IP address is a unique number assigned to a terminal for connection to the
Internet. The format is a string of four dot-separated three-digit numbers. (Example:
111.112.xxx.xxx)
