<Problem>
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 cards (NIC) being
used with the same computer?
Set only the network 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"
씮
"System"
씮
"Device Manager"
씮
"Network Adapter" and then click [Properties
(R)] and set the device usage to "Not used".
<Problem>
Sometimes it takes a long time for screen transmission from the
personal computer to the projector. (IEU 1.0)
Check Points
Countermeasures
• 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 performance 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.
The resolution of MT1065, MT1060, LT260 and
LT240 is 1024 x 768 dots.
The resolution of LT220 is 800 x 600 dots.
