IP Setup If the projector is connected to a DHCP 
network, select Obtain an IP address 
automatically.
 If the projector is used with a static IP, 
select Use the following IP address:, and 
then specify the values for IP Address, 
Subnet Mask, and Default Gateway.
 You cannot specify prohibited IP addresses 
such as 0.0.0.0 and 255.255.255.255.
DHCP Server Setup If the projector is connected to computers, 
it functions as a server and can assign IP 
addresses to the computers. If you want 
the projector to assign IP addresses, select 
Auto.
 If you select Auto, select Obtain an IP 
address automatically for the TCP/IP set-
tings in the computer.
 The range in which the IP addresses are 
assigned is displayed in Start IP and 
End IP. These IP addresses are changed 
automatically if the IP address of the pro-
jector is changed.
Wireless Setup You can choose Enable or Disable for 
Wireless LAN. If you selected Disable 
for Wireless LAN, you can enable it again 
by connecting using Wired LAN or perform-
ing NETWORK RESET in the WIRELESS 
menu of the projector.
 You can specify a value of 14 digits that fol-
low Wireless Projector as a SSID.
 If you enable SSID Broadcast, you can 
search Wireless Projector automatically. 
Also, you can disable SSID Broadcast for 
security improvement. If you selected Dis-
able for SSID Broadcast, you can enable 
it again by connecting using Wired LAN or 
performing NETWORK RESET in the 
WIRELESS menu of the projector.
Channel The model for North America has 11 chan-
nels, and that for Europe has 13 channels. 
If you select Auto, you can select a chan-
nel, which is in an optimum radio wave 
environment, from the above channels.
 If the radio wave environment is poor dur-
ing use, switch to another channel manu-
ally.
WEP You can improve security for the wireless 
communication by encrypting it between 
the projector and computers.
 If you use the WEP function, select 128-bit 
(ASCII: 13 characters), 64-bit (ASCII: 5 
characters), 128-bit (Hex: 26 digits), or 64-
bit (Hex: 10 digits). Specify a key according 
to the number of the characters/digits.
 You are required to enter the above speci-
fied key when connecting the projector

TCP/IP Transmission Control Protocol/Internet Protocol 
(TCP/IP) is the standard protocol used for network-
ing. Protocol is a set of technical rules for the trans-
mission of information between computers.
IP Address IP Address is the numbered address to identify a 
server for networking. Internet Protocol (IP) is the 
protocol to transmit data over the Internet, and the IP 
Address, which consists of exactly same numbers as 
the other address in one network, is not available.
DHCP Dynamic Host Configuration Protocol (DHCP) is the 
protocol dynamically allocating IP addresses to com-
puters on a local area network. The computer with 
DHCP server can assign IP address to each com-
puter on a local area network automatically.
Subnet Mask Subnet is the separated part of network, and subnet 
mask is a number that defines a range of IP 
addresses that can be used in the network.
Gateway Gateway is either hardware or software that acts as 
a bridge between two networks. Gateway is a sys-
tem for transmitting data across networks that are 
incompatible and use different protocols.
WEP Wired Equivalent Privacy (WEP) is a security proto-
col that adds security by encrypting data. The 
encryption key enables only the authorized systems 
on the network to recognize the data.
SSID Service Set ID (SSID) is the identifier for wireless 
local area networks, which identifies the access 
points necessary for transmitting. Some wireless 
local area network card uses [ESSID (Extended Ser-
vice Set Identifier)] or network name as SSID.Settings Contents
Resolution The resolution of this projector is fixed at XGA.
Color DepthYou can specify the number of colors for the pro-
jected images.

or High (32 bit) (16,777,216 colors).
Screen Refresh Rate The rate of this projector is fixed at 75 Hz.
Login CodeYou can specify the login code to connect to the 
projector wirelessly.
 Disable: You can connect to the projector wire-
lessly without entering the login code.

How to use wired LAN connection
The function described in the previous section for the wireless connection can be applied also to the wired LAN connection similarly.
When the wireless connection is poor and the network settings cannot be configured, use the function.
For Ethernet connection  
1. Connect one end of the Ethernet cable to the LAN terminal of the projector.
 Use a cross cable.
 Use a Category 5 cable.
2. Connect the other end of the Ethernet cable to the Ethernet port of the computer.
 To project images, use the connection software. For details, see the sections B - F and G. Projecting images in Projecting images wire-
lessly. (See page 21 and 22.)
Important: When the wireless environment is poor, if you want to configure the network settings securely, or in other cases, use the connection.
 When turning on the devices, turn on the projector first, and then turn on the computer after the screen of the projector appears. If you turn on 
the computer first, the projector may not operate properly.
 Specify the settings for the Internet Protocol (TCP/IP) properties in Local Area Connection according to those specified in Changing the net-
work settings (See page 27). In the default settings, Obtain an IP address automatically is selected.
 When you use the wired LAN connection, the MONITOR OUT terminal, AUDIO-IN terminal, and AUDIO-OUT terminal cannot be used.
 Do not touch the LAN terminal directly with your hand as you may be shocked by static electricity.
