Telnet Tips

It is not the intention of this guide to detail all of the operations and functionality of Telnet; however, some basic level of understanding is necessary for operating the MPX 866 A matrix switcher via Telnet.

Open

Connect to the MPX 866 A matrix switcher using the Open command. Once you are connected to the switcher, you can enter the SIS commands the same as you would if you were using the RS-232 of RS-422 link.

Connect to the MPX 866 A matrix switcher as follows:

1.At the Telnet prompt, type open {IP address} and then press <Enter>.

If the switcher is not password protected, no further prompts are displayed until you break or disconnect the connection to the matrix switcher.

If the switcher is password protected, Telnet displays the password prompt.

2.If necessary, at the password prompt, type the appropriate password and then press

<Enter>.

Connection to the switcher via the Ethernet can be password protected. There are two levels of password protection: administrator and user. A person logged on as an administrator has full access to all matrix switcher switching capabilities and editing functions. Users can create ties, set mutes, and view all settings with the exception of passwords. By default, the MPX 866 A matrix switcher is shipped with both passwords set to {carriage return}.

Once you are logged in, the switcher returns either Login Administrator or Login User. No further prompts are displayed until you break or disconnect the connection to the MPX 866 A matrix switcher.

Escape character and Esc key

When Telnet is first started, the utility advises that the Escape character is ‘Ctrl+]’. Many SIS commands include the keyboard <Esc> key. Consequently, some confusion may exist between the Escape character and the Escape key.

The Telnet Escape character is a key combination, the <Ctrl> key and the <]> key pressed simultaneously, which returns you to the Telnet prompt while leaving the connection to the MPX 866 A matrix switcher intact.

The Escape key is the <Esc> key on the computer keyboard.

Local echo

Once connected to the MPX 866 A matrix switcher, by default, Telnet does not display your keystrokes on the screen. SIS commands are typed in blindly and only the SIS responses are displayed on the screen. To command Telnet to show keystrokes, at the Telnet prompt, type set local_echo and then press <Enter> before you open the connection to the switcher.

With local echo turned on, keystrokes and the responses of the switcher are displayed on the same line. For example: 1*1!In1 Out1 All, where 1*1! is the SIS command and In1 Out1 All is the response.

With local echo turned on, all keystrokes are displayed, even those that should be masked, such as the password entry. For example, when entering a password with local echo turned on, you see a display such as a*d*m*i*n*, where admin is the keyed in password and

*****is the masked response.

You can turn off local echo by typing unset local_echo and then pressing <Enter> at the Telnet prompt. If you are connected to the MPX 866 A matrix switcher and need to access the Telnet prompt to turn local echo off, type the Escape character (<Ctrl>+<]>).
