IP address defined other than its own. If the ARP table is empty, the command will return an error

message. Type ARP -A at the DOS command prompt to verify that there is at least one entry in the

ARP table.

If the local machine is the only entry, ping another IP address on your network to build a new entry

in the ARP table; the IP address must be a host other than the machine on which you are working.

Once there is at least one additional entry in the ARP table, use the following command to ARP the

IP address to the Ethernet Interface:

TELNET TO PORT 1

Now open a Telnet connection to Port 1. The connection will fail quickly (3 seconds). But the

Ethernet Interface will temporarily change its IP address to the one designated in this step.

TELNET TO PORT 9999

Finally, open a Telnet connection to port 9999 and set all required parameters.

CLEARING THE ARP TABLE

Clearing an entry in the ARP table should be performed before and after setting the IP Address that

you will be using. In command prompt, type the following (insert your IP Address). Then press the

Enter key.

NOTE: This IP address is temporary and will revert to the default value when the Ethernet

Interface's power is reset, unless you log into the Ethernet Interface and store the changes

permanently.

Configuration

Certain parameters must be configured before the Ethernet Interface can function on a network. The

Ethernet Interface can be locally or remotely configured using the following procedures:

Use a Telnet connection to configure the unit over the network. The Ethernet Interface's

configuration is stored in nonvolatile memory (NVRam) and is retained without power. The

configuration can be changed at any time. The Ethernet Interface performs a reset after the

configuration has been changed and stored.

As mentioned above, to configure the Ethernet Interface over the network, establish a Telnet

connection to port 9999. From the Windows Start menu, click Run and type the following

command, where x.x.x.x is the IP address and 9999 is the Ethernet Interface's fixed network

arp -s 191.12.3.77 00-20-4a-xx-xx-xx

telnet 191.12.3.77 1

telnet 191.12.3.77 9999

arp -d 191.12.3.77
