[Select Port]
Select either AUI or 10BASE-T. When connecting to the 10BASE-T connector (LAN) of
V7i, select [10BASE-T]. Select either [10BASE-T] or [AUI] when CU-03 is mounted.

[Memory Protect]
Attach a check mark ( ) when write-protecting the internal memory or memory card.
[Default Gateway]
Attach a check mark ( ) when setting the default gateway.
[Subnet Mask]
Attach a check mark ( ) when setting the subnet mask. When this option is checked, it
is set to [255.255.255.0].

IP Address
This is an address that is used for recognizing each node on the Ethernet and should be unique.
The IP address is 32-bit data which consists of the network address and the host address and can
be classified into A to C depending on the network size.

be classified into A to C depending on the network size.
Notation
A string of 32-bit data is divided into four, and each segment delimited with a period is in
decimal notation.
Example: The IP address in class C shown below is represented as “192.128.1.50.”

Port No.
Multiple applications are running on each node, and communications are carried out for each
application between the nodes. Consequently, it is necessary to have a means to identify the
application that data should be transferred to. The port number works as this identifier. Each port
number is 16-bit data (from 0 to 65535). However, since some numbers are already used, the
setting range available with V7i is from 2049 to 65535. It is recommended to set a greater
number.

Default Gateway
A gateway and a router are used for communicating between different networks. The IP address
of the gateway (router) should be set to communicate with the node(s) on other network.
