Figure 3: HyperTerminal Configuration Screen #3

8.2 Telnet

The console is also accessible via a Telnet interface for remote administration over Ethernet once the unit is communicating on the network. The Telnet console uses well-known port 23. Note that although only 1 telnet console session can be active at any given time, the telnet console and RS232 console operate independently and can be used simultaneously.

8.2.1 Requirements

All that is needed is a computer with telnet software that can access the ETH-100 over the Ethernet network. Telnet software is typically included as a standard component of Microsoft Windows and other PC operating systems.

8.2.2 Connection

No special connections are required, other than the PC running the Telnet application must be able to logically connect to the ETH-100 to be configured.

8.2.3 Application Configuration

Although any software vendor’s Telnet client application can be used, the configuration example given here will use the Microsoft Windows Telnet application. To start the Telnet application, simply type “telnet” at either a DOS (command) prompt or in the “Start…Run” window. Once the telnet client screen opens, the target device can be accessed simply by typing “open” at the Telnet prompt with the ETH-100’s IP address as an argument. Refer to Figure 4.
