TCP/IP Module IP Address/Configuration Using Telnet
Overview
Telnet and ARP are utilities available in Windows operating systems and are used in the TCP/IP addressing
procedure:
Telnet
- Telnet is a terminal emulation program for TCP/IP networks such as the Internet. The Telnet program runs
on your computer and connects your PC to a server on the network. You can then enter commands through the
Telnet program and they will be executed as if you were entering them directly on the server console. This enables
you to control the server and communicate with other servers on the network.
ARP
- ARP is a TCP/IP protocol used to convert an IP address into a physical address (called a DLC address),
such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the
TCP/IP network. The host on the network that has the IP address in the request then replies with its physical
hardware address. ARP will only work when the console and PC share the same subnet.
Port Number
- This setting represents the source port number in TCP connections. It is the number that identifies
the channel for remotely initiating connections. The range of permissable port numbers is 1 - 65535, except for the
following reserved port numbers:
Do not use any of the reserved port numbers on any version of the TCP/IP board.
In addition to the IP address configuration instructions provided in this manual, it may also
be possible to use the Lantronix device installer found in the Lantronix website
(
www.lantronix.com
) to configure your TCP/IP module’s IP address.
