■ What is an IP Address?

The IP Address is a number for identifying devices connected to the network. An IP address must be
assigned to each device using network values.

Connecting the projector and a computer via a wireless connection is the same as the computer and
projector being connected to a wireless LAN network. Therefore, if the projector (and computer) is not
assigned an IP address, they cannot be identified and thus a wireless connection cannot be possible.

192.168.150.150

192.168.150.153

192.168.150.154

192.168.150.151

192.168.150.152

■ Assigning IP addresses

When creating a local network where the projector and a computer are connected in a wireless environment,
192.168.0.1 to 192.168.255.254 can be assigned as the IP addresses for a local network for the devices
connected to that network.
The IP address of the projector is 192.168.0.1 and as long as there are no conflicts, the default settings do
not have to be changed.

Example
• Projector ................192.168.150.150

• Computer (no. 1) ...192.168.150.151

• Computer (no. 2) ...192.168.150.152

This projector comes with a DHCP server function that automatically assigns IP addresses to devices
connected to the network.
For details, see 

Note

• The range of IP addresses that can be assigned in a local network is fixed.

• IP stands for Internet Protocol.

■ What is a DHCP server function?

The DHCP server function automatically assigns IP addresses to devices connected to the network. When
the Network Settings on the computer have been set to Automatically get IP address (DHCP server enabled),
the projector will automatically assign IP addresses.

Make the following settings when using this function

1Set the DHCP server function on the projector to ON.
2Set the start value of the IP address assigned and an expected number of IP address to be automati-

cally assigned (Maximum number to be assigned).

Note

• DHCP stands for Dynamic Host Configuration Protocol.

■ What is a wireless channel?

A wireless channel is a frequency used by wireless LAN PC cards when communicating. For IEEE802.11b
standard, 14 channels can be used. If other wireless LAN networks are being used near the location where
the projector is, make sure that different channels have been set to avoid interference.

■ Assigned wireless channels

If there are no other networks that can cause interference nearby, set either 1, 6, or 11.
If there are no interferences on 11 channel settings, you do not have to change the default settings.

• If the card is removed without selecting

“Eject PC Card” in step 1 above, the data
stored on the PC card may be lost, or the
PC card may be damaged.

• When moving the projector, make sure to

eject the PC card and that the Eject button is
pressed all the way in. If moved with the Eject
button out, the projector may be damaged.
