Normally, you are required to change them because they are located on a different local network
from that of your development workstation. Without changes, you cannot connect to them directly.
Use the netconfig utility to complete the task. Type netconfig -h to get help on this utility.
\> netconfig -h
Usage: netconfig –n <“LAN1” or “LAN2”> [-m <netmask>] [-d <DNS server>] [-g <gateway>]
[-i <IP address>]
For example, your development workstation has a LAN port at 192.168.1.x and the Domain Name
Server (DNS) is at 192.168.2.6. Execute the following command.
\> netconfig –n LAN1 –i 192.168.1.5 –m 255.255.255.0 –g 192.168.1.254 –d 192.168.2.6
Use command netconfig to view the new settings.
\> netconfig
LAN1 Interface Configuration:

Operating Your UC-7400-CE Computer Via Telnet Client
Before operating your UC-7400-CE computer using the Telnet client, we suggest that you change
the network settings of the computer (see the earlier section) to have at least one of the two
network ports situated in the same LAN as your development workstation.
Use a cross-over Ethernet cable to directly connect your development workstation to the target
computer, or a straight-through Ethernet cable to connect the computer to a LAN hub or switch.
Next, use a telnet client in your development workstation to connect to the telnet console utility of
the target computer. Upon a successful connection, type the login name and password as requested
to logon to the computer.
After logging in via the console port or a telnet client, you have a list of busybox commands
available to operate the computer. Use HELP to display all the commands, or type HELP
[command name] to display extended help for the selected command. Some of these commands
such as DATE and TIME are very useful to you to easily manage the system time of the computer.
Others commands such as DIR and MKDIR are good utilities for file management. For example,
to inspect the file structure of the root directory, type DIR
\> dir /b
