Projection to the screen is not possible when using the LAN environment. (DIU 2.0, IEU 1.0)
Check PointsCountermeasures
Have LAN cards (i.e., adapters) been put into both the personal
computer and the projector?Put LAN cards (i.e., adapters) into both the personal computer
and the projector.
Have the LAN settings (for both the personal computer and the
projector) been completed?Perform the LAN settings for both the personal computer and
the projector.
Are a wired LAN and a wireless LAN being used simultaneously
with the same personal computer?Please cancel either one of the LAN connections. When a built-
in type is used, set it to "not used" under Properties.
Image Express Utility 1.0 does not support the following:
(1) Software using Direct X
(2) MS-DOS screens
(3) Microsoft Office assistant
(4) IME
(5) When starting a moving video application first or using some computer’s environments, sending a moving video image may not
be possible.
 Operation of this projector software becomes unstable. (DIU 2.0, IEU 1.0)
Check PointsCountermeasures
When the network settings of the projector or personal
computer are changed while this projector software (i.e.,
Dynamic Image Utility 2.0 or Image Express Utility 1.0) is
starting or running, the operation of the projector software may
become unstable.Please restart the projector and the personal computer. When
changes are to be made to the network settings, exit the
projector software before making the changes.
An application error occurs under Image Express Utility 1.0
when the screen resolution is changed during Continuous
Transmit.When changes are to be made to the screen resolution, exit
Image Express Utility 1.0 before making the changes.
The colors become strange when Windows is set to 256 colors. (IEU 1.0)
Check PointsCountermeasures
Image Express Utility 1.0 does not support 256 colors. Please set the Windows number of colors setting to High Color
(15 bit) or higher.
6. Using the Projector in a Network
On the LT260K and LT240K, images cannot be sent from the
“Dynamic Image Utility 2.0” on a PC to the projector on the
Continuous Transmit of the Image Express Utility 1.0.Quit the Continuous Transmmit in the Image Express Utility 1.0
and then send the image from Dynamic Image Utility 2.0. 
						

							6-10
 The projector cannot be found with "General search". (IEU 1.0)
Check Points Countermeasures
Are the wireless LAN settings appropriate?
Are the channel numbers for the personal computer and the
projector set to the same number?
When WEP (encryption) has been set, has the same value been
set for both the personal computer and the projector?Please check the access points, the personal computer setting
values and the projector [LAN Mode] setting values.
When using the infrastructure or 802.11 Ad Hoc, please set to
the same character string since SSID distinguishes between
upper and lower case characters.
Are radio communication conditions satisfactory? Check whether there are obstacles located between the
access point and the personal computer. Try moving the
personal computer closer to the access point.
Are the TCP/IP settings (e.g., IP address, sub net mask, etc.) of
the personal computer and the projector correct?Check whether the network settings are within the same
segment.
Are more than one network interface cards (NIC) being used
with the same computer?Set only the network interface card (NIC) that is connected to
the projector to "Valid".
For a network card that is not connected to the projector, click
the network card name under "Control Panel" 
 "System" 

"Device Manager" 
 "Network Adapter" and then click
[Properties (R)] and set the device usage to "Not used".
 Sometimes it takes a long time for screen transmission from the personal computer to the
projector. (IEU 1.0)
Check PointsCountermeasures
• Transmission time may be long depending on the image
pattern.
• When screens are sent to multiple projectors simultaneously,
a larger number of projectors will result in longer transmission
times.
• The transmission time may vary depending on the network
environment.
• The transmission time may vary depending on the perfor-
mance of the personal computer as well as other application
software that is running at the same time.
Transmission time will be longer when the resolution of the
personal computer and that of the projector differ since there
will be an increase in resolution conversion processing.We recommend that the resolution of the personal computer
and that of the projector be set to the same setting value
(except GT6000).
The resolution of GT5000, MT1065, MT1060, LT260, LT240,
LT260K, LT240K and WT600 are 1024 x 768 dots.
The resolution of LT220 and MT860 are 800 x 600 dots.
Select the resolution to 1024 x 768 on your PC for sending an
image to GT6000.
 Cannot follow the screen switching processing of the PowerPoint slide show, etc. (IEU 1.0)
Check PointsCountermeasures
Smooth screen switching processing or animation effects
cannot be followed because in Image Express Utility 1.0, the
screen condition of the personal computer is sent to the
projector at a fixed time interval.Use the software with " the PowerPoint screen switching
effects, animation effects, and other settings set to "None".

							6-11
6. Using the Projector in a Network
 When used in the LAN environment, the projector cannot be detected. (DIU 2.0, IEU 1.0)
Check PointsCountermeasures
If you have a personal firewall installed on your computer, the
personal firewall may not allow for communication with the
projector.Try setting the personal firewall to allow for communication with
the projector.
For procedures for setting the personal firewall, read the on-line
help or the user guide included with the personal firewall.

z Stacking and Connecting the Projectors
Master projector
Slave projector
NOTE: Up to two units can be gravity stacked without external support. In some
cases, however, two images will not align on the screen correctly. This will become
more apparent when displaying small text and detailed graphics.
NOTE: Do not stack both the GT5000 and GT6000 projectors together.
CAUTION: To prevent the projectors from falling, install them in a place and fasten them in a
way with sufficient strength to support the two projectors. The projector with a lens weighs 21
kg/46.3 lbs.
z-1. Assigning Projector IDs
You can operate multiple projectors with the same remote con-
trol.
To do so:
z-1-1. Select [Projector Options] →[Link Mode] →[Settings]→
[Projector ID] a-nd assign an ID number to each projector. See
also page 8-18.
z-1-2. Select the same communication speed for both the pro-
jector.
NOTE: Do not turn on [Master] or [Slave] at this time.
z-1-3. On the remote control specify the ID number of the pro-
jector to be adjusted. Press and hold the CTL and press
MENU (ADDRESS) button to enter the ID number.
You can operate the projector assigned the same ID number
as the remote control.
NOTE: Specifying "None" for projector ID allows you to operate multiple projectors
concurrently. However, some projectors may not synchronize to the other projec-
tors.

Recommended Throw Distances for Double Stack
NOTE:
• The optional lenses for GT6000/GT5000 have different geometrical distortions in wide zoom and tele. Select the best zoom position for stacking where the geometrical
distortion is as small as possible.
• The optional lens GT06RLB and GT10RLB do not support stacking.
For double stacking, follow the instructions described below.
z-2. Stacking the Projectors
Place the projectors at the proper height for best screen to projector relationship. Make sure that all projectors have the same display
orientation.Screen Size
