Installing LX-100 Series (LAN 1394 model)
2-12
About IP Address Settings
Consult your network administrator when connecting the LX-100 series to your network per the following
information. Basic knowledge about the Windows network system is required to set the network connection
parameters.
■ The default settings of the LX-100 Series are as follows. Modify the settings (such as the IP address) as
necessary. How to change: Click the portion of the IP address in LX Network dialogue to display LX Property
dialogue. You can create settings for parameters of the IP address or recorder name (Name). (For detail of
the settings, refer to the next item of “Starting Program” )
IP address: 192.168.0.10
Subnet mask: 255.255.255.0
Gateway: 0.0.0.0
DHCP client: DISABLE
■ To communicate at 100 Mbps, all devices in the path from the LX-100 to the controller PC must support
100 Mbps. Use a cable that is Category 5 or better. To ensure communication quality, we recommend that
you use STP cables and a switching hub that supports STP cables.
■ Depending on the network environment being used, it is possible that you will encounter delays in data
transmission or congestion in processing. In such a case, try the following to improve the situation:
1) If a repeater hub is being used, change to a switching hub instead.
2) Reduce the number of broadcast packets as much as possible.
3) Use a communications path that does not pass through a router as much as possible.
■ However, in a situation such as when the LX-100 is in a remote location and communications are
constrained by low-speed paths, use the LX-100 with a reduced sampling rate.
■ The LX-100 LAN interface carries out TCP connection continuous communications. However, if a packet
from the other party does not arrive within 180 seconds, a timeout occurs and the other party is
automatically disconnected. So, in the event that a normal termination was not possible because of some
problem, such as a PC hang-up or disconnected cable, wait 180 seconds and then try reconnecting.
■ If the PC enters a standby status while LX Navi is being used, communications will cease, and a timeout
will cause a disconnection. If you are using the PC for a long time, make sure that the system standby setting
in the Windows power options is not selected.
■ With the LX-100 LAN interface, the LX-100 can be operated as a DHCP (Dynamic Host Configuration
Protocol) client, but if an IP address cannot be obtained within 30 seconds after startup, the LX-100 starts
those usual operations with a fixed IP address.
■ If you establish a firewall on your PC or install virus check software, you may not connect the LX. Check
the security level of the program on your PC. The ports to be used at LX Navi (LAN model) are as follows:
Control port 49408 (TCP)
Data transfer port 49664 (TCP)
UDP port 49920 (UDP)
For other settings, such as IP address parameter settings and network usage, consult your network
administrator before using the LX-100.
