Preparation
Preparing an Internet Environment
Since the protocol UDP (user datagram protocol) is used for WIRES-X communications via the Internet, some menu settings are
required depending on the Internet connection method.
Setting the PC and the router
Why is the setting required?
●
Opening communication port
The WIRES-X server communicates with the PC used as a node station via specified ports (46100, 46110, 46112, 46114, 46120 and
46122).
When using a router to connect the PC to the Internet, the UDP port must go through the router as well; however, communications
using these ports are generally prohibited on commercially available routers in the default setting.
Therefore, if you are using a router, make sure that the UDP ports are “open” for passing UDP traffic.
Tip
If you do not use a router, this setting is not required. In this case, after installing the WIRES-X software, perform the internet access permission setting
(See page 20) to use WIRES-X immediately.
●
Assigning a static IP address
Generally, the DHCP (Dynamic Host Configuration Protocol) function of the router assigns an IP address automatically because of
the Internet connection setting on Windows PCs by default. In this setting, every time you start the PC, a new IP address may be
assigned.
If a new IP address is assigned automatically to the node PC when starting the PC, the address may be different from the one
specified on the router. It disables communications with the WIRES-X server.
On the other hand, when ports are open on the router, the communication destination of the port (a PC) is specified with an IP
address.
To enable communications, assign an IP address to the node PC and specify this address when opening ports on the router.
Setting an IP address on the PC
●
Selecting an IP address
The IP address set on the node PC differs depending on the router.
The steps are shown as follows:
1
Click the Windows Start button
2
Click [Control Panel]
3
Click [Network and Internet], then [Network and Sharing Center]
