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 

TDPJ 

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)
