Video Wall  Projection
Info
•Before setting up the video wall projection, install Internet Explorer (version 5.0 or later).
•Video wall is not compatible with resolutions higher than SXGA.
•Image quality may deteriorate when picture signals are input through multiple projectors with an RGB
cable or an RCA cable in a daisy chain connection.
Hub
Usually, a costly image-processing device is required to set up a video wall projection.
This projector has built-in video wall capability that doesn’t require additional equipment.

•The projector will be assigned to the part of
the video wall.
Note
•For more details on the assigned position
and the actual position of the projector, see

Video Wall Setup” (page 44).
5Repeat the same procedure from
the step 1 to 4 for the other three
projectors.
That completes the video wall setup. When
the same image signal is input to all the
projectors, the video wall projection starts.

Notes on the Wide Video Wall Projection
Selecting “2 X 1”, “3 X 1”, “4 X1”, “5 X 1”, “6 X 1”, “7 X 1” or “8 X 1” on “Division” (see page 43 ) allows you to
create the wide video wall.
To  create the wide video wall with three projectors lining up in single file from left to right (as shown above),
select “3 X 1” on “Division”, select a position for each projector, and then input the image which width is
compressed at 1/3 (as shown below).

Setting up the Video Wall Projection  Application
Using “Stack Setting” and “Set Inputs” functions together allows you to control the video wall with one
remote control.
This part shows an example of a connecting procedure for inputting the video signals to the video wall
based on the example in the previous section.

1Change the TCP/IP settings for the
computer as shown below.
(See “Setting an IP Address for the Computer”
on page 19 for the details.)
•IP address : 192.168.150.2
•Subnet mask : 255.255.255.0
•Default gateway : (Do not input any values.)
2Change the TCP/IP settings for
each projector as shown below.
(See “Setting up a Network Connection for the
Projector” on page 21 for the details.)
•IP address Projector 1 : 192.168.150.3
Projector 2 : 192.168.150.4
Projector 3 : 192.168.150.5
Projector 4 : 192.168.150.6
•Subnet mask : 255.255.255.0
•Default gateway : 0.0.0.0
Note
•The TCP/IP settings shown are examples
to make connections following the diagram.
•When using other equipment in the same
network, be careful about the IP address
overlap or other network settings.
•Consult your network administrator for as-
sistance with the network settings.
3Connect the computer and the pro-
jectors as shown below.
■Preparation
•Follow the procedure below after setting up the basic connection.
•When “User Name” and “Password” have been set to the projector, reset them before the stack projection
setup. To set “User Name” and “Password”, use the same user name and password for both of the
master and slave projectors. (See page 25.)
•Set “Data Port” with the same number for both of the master and slave projectors. (See page 26.)
Info
•Do not use network software or equipment while it is accessing the projector via the port of the same
number used for the master or slave projector, otherwise you cannot properly control multiple projectors
with one remote control.

16Make connections following the
diagram shown on page 46.
17Turn on the projectors first, then
turn on the computers and the
video equipment.

Communication cannot be established with the projector
When connecting the projector using serial-connection
\Check that the RS-232C terminal of the projector and a computer or the commercially
available controller are connected correctly.
\Check that the RS-232C cable is a cross-over cable.
\Check that the RS-232C port setting for the projector corresponds to the setting for the
computer or the commercially available controller.
When connecting the projector to a computer using network (LAN)-
connection
\Check that the cable’s connector is firmly inserted in the LAN terminal of the projector.
\Check that the cable is firmly inserted into a LAN port for a computer or a network device
such as a hub.
\Check that the LAN cable is a Category 5 cable.
\Check that the LAN cable is a cross-over cable when connecting the projector to a computer
directly.
\Check that the LAN cable is a straight-through cable when connecting the projector with a
network device such as a hub.
\Check that the power supply is turned on for the network device such as a hub between the
projector and a computer.
Check the network settings for the computer and the projector
\Check the following network settings for the projector.
•IP Address
Check that the IP address for the projector is not duplicated on the network.
•Subnet Mask
When the gateway setting for the projector is “0.0.0.0” (Not Used), or the gateway setting for
the projector and the default gateway setting for the computer are the same:
•The subnet masks for the projector and the computer should be the same.
•The IP address parts shown by the subnet mask for the projector and the computer should
be the same.
(Example)
When the IP address is “192.168.150.2” and the subnet mask is “255.255.255.0” for the
projector, the IP address for the computer should be “192.168.150.X” (X=3-254) and the
subnet mask should be “255.255.255.0”.
•Gateway
When the gateway setting for the projector is “0.0.0.0” (Not Used), or the gateway setting for
the projector and the default gateway setting for the computer are the same:
•The subnets for the projector and the computer should be the same.
•The IP address parts shown by the subnet mask for the projector and the computer should
be the same.
(Example)
When the IP address is “192.168.150.2” and the subnet mask is “255.255.255.0” for the
projector, the IP address for the computer should be “192.168.150.X” (X=3-254) and the
subnet mask should be “255.255.255.0”.
•Data Port
Other computers should not use the data port of the projector.
The data port should be used for communication during the stack projection.
Note
•The factory default setting of the network setting for the projector
IP address : 192.168.150.2
Subnet mask : 255.255.255.0
Gateway address : 0.0.0.0 (Not Used)
•For network settings for the projector, refer to page 21.
