Troubleshooting

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 ﬁ rmly inserted in the LAN terminal of the projector.

?Check that the cable is ﬁ rmly 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.

?If all of the above are unsuccessful, restart the network function using “Network” - “Restart Network”. (See page 55 of the projector’s operation manual.)

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)

Note

•When “DHCP Client” is set to “OFF” on 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 15.
