IE-CS(T)-2TX-xRS232/485
IE-CS(T)-2TX-xRS232/485 will not have a valid connection to the network). First time users may refer to
Chapter 3, Initial IP Address Configuration, for more information.
You can choose from four possible IP Configuration modes—Static, DHCP, DHCP/BOOTP, and
BOOTP—located under the web console screen's IP configuration drop-down box.

IP address
Setting
E.g., 192.168.1.1 (IP
addresses in the form
x.x.x.0 and x.x.x.255
are invalid.)
An IP address is a number assigned to a network device (such as a computer), which works as a permanent
address on the network. Computers use IP addresses to identify and talk to each other over the network.
Choose a proper IP address that is unique and valid in your network environment.
Netmask
Setting
E.g., 255.255.255.0
A subnet mask represents all the network hosts at one geographic location, such as all the hosts in a building
or on the same local area network. When a packet is sent out over the network, the IE-CS(T)-2TX-xRS232/485
will use the subnet mask to check whether the desired TCP/IP host specified in the packet is on the local
network segment. If the address is on the same network segment as the IE-CS(T)-2TX-xRS232/485, a
connection is established directly from the IE-CS(T)-2TX-xRS232/485. Otherwise, the connection will be
established through the given default gateway.
Gateway
Setting
E.g., 192.168.1.1
A network gateway acts as an entrance to another network. Usually, the computers that control the traffic
within the network or at the local Internet service provider are gateway nodes. The IE-CS(T)-2TX-xRS232/485
needs to know the IP address of the default gateway computer in order to communicate with hosts outside the
local network environment. To obtain correct gateway IP address information, consult your network
administrator.
