IP Access Configuration & Operation

Telnet Console

The CAT-32 IP firmware features a Telnet server that enables a user to connect via a standard Telnet client. If the Telnet program is using a VT 100, VT 102 or VT 220 terminal or appropriate emulation, it is even possible to perform a console redirection, as long as the CAT-32 IP host is using a text mode screen resolution.

Connecting to the CAT-32 IP is done as usual and as required by the Telnet client, for instance in a UNIX shell:

telnet 192.168.1.22

Replace the IP address by the one that is actually assigned to the CAT-32 IP. This will prompt for the username and password in order to log into the device. The credentials that need to be entered for authentication are identical to those of the web interface. That means the user management of the Telnet interface is entirely controlled with the appropriate functions of the web interface.

Once you have successfully logged into the CAT-32 IP a command line will be presented and you can enter management commands directly.

In general, the Telnet interface supports two operation modes: the command line mode and the terminal mode. The command line mode is used to control or display some parameters. In terminal mode the pass-through access to serial port 1 is activated (if the serial settings were made accordingly). All inputs are redirected to the device on serial port 1 and its answers are displayed on the Telnet interface.
