Communication cannot be established with the monitor
When connecting the monitor using serial-connection
\ Check that the RS-232C terminal of the monitor 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 monitor corresponds to the setting for the computer
or the commercially available controller.
When connecting the monitor to a computer using network (LAN)-connection
\ Check that the cable’s connector is firmly inserted in the LAN terminal of the monitor.
\ 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 monitor to a computer
directly.
\ Check that the LAN cable is a straight-through cable when connecting the monitor 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
monitor and a computer.
Check the network settings for the computer and the monitor
\ Check the following network settings for the monitor.
• IP Address
Check that the IP address for the monitor is not duplicated on the network.
• Subnet Mask
When the gateway setting for the monitor is “0.0.0.0” (Not Used), or the gateway setting for
the monitor and the default gateway setting for the computer are the same:
• The subnet masks for the monitor and the computer should be the same.
• The IP address parts shown by the subnet mask for the monitor 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
monitor, 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 monitor is “0.0.0.0” (Not Used), or the gateway setting for
the monitor and the default gateway setting for the computer are the same:
• The subnets for the monitor and the computer should be the same.
• The IP address parts shown by the subnet mask for the monitor 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
monitor, 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”.
Note
•When “DHCP Client” is set to “OFF” on the monitor
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 monitor, refer to page 14.
