TCP/IP Module

5] SETTINGS AND MENUS

The TCP/IP module settings listed in the following sections can be confi gured using one or
both of these methods.
- "Confi guring Via Serial Port" on page 5,
- "Confi guring Via Serial Port" on page 5,
- "Confi guring Via Web" on page 11.

Local IP Address

This is the Internet Protocol (IP) address of a device communicating on a LAN. Each TCP/
IP module must have a unique Local IP Address. The address entered must be recognized
by the LAN and must not be used by another device. A Local IP Address is entered as four
sets of three digits (000-255) separated by periods (i.e. 206.104.032.006). Speak to your
Network Administrator about obtaining an IP address.
Serial Port: Yes (Menu [1], [2])
Web Page: Yes (Network Settings tab)
The fi rst time you set the module's Local IP Address, you must do so using the serial port method
as described in "Confi guring Via Serial Port" on page 5.

Local Port Number

The Local Port Number is assigned to the data transfer application program that
communicates through the TCP/IP module's physical serial connector for initiating remote
connections with the LAN. Enter a value between 0 and 65535. Do not use Well-Known
Ports, which are port numbers used by everyone. For example, port 80 is used for HTTP
traffi c (Web traffi c). Speak to your Network Administrator about obtaining a port number.
Serial Port: Yes (Menu [1], [2])
Web Page: Yes (Network Settings tab)

Subnet Mask

Whenever the TCP/IP module wants to communicate with another device on the LAN, it will
compare its Local IP Address with that of the device. The result is then matched with the
assigned Subnet Mask number to determine
whether the device's IP Address belongs to the same subnet (LAN segment) as the module.
If not, data will be directed towards the Gateway Address (see below) to redirect the data
to the correct subnet via a router. A Subnet Mask is entered as four sets of three digits
(000-255) separated by periods. A common Subnet Mask number is 255.255.000.000.
Speak to your Network Administrator about obtaining a Subnet Mask number.
Serial Port: Yes (Menu [1], [2])
Web Page: Yes (Network Settings tab)

Gateway Address

The Gateway Address enables the TCP/IP module to communicate with other LAN segments.
Enter the Local IP Address of the router connected to the same LAN segment as the TCP/
IP module. The Gateway Address must be within the local network. A Gateway Address is
entered as four sets of three digits (000-255) separated by periods (i.e. 206.104.032.006).
