Telnet tips

It is not the intention of this manual to detail all of the operations and functionality of Telnet; however, some basic level of understanding is necessary for operating the ISM 824 via Telnet.

Open

Connect to the ISM 824 using the Open command. Once your computer is connected to the switcher, you can enter the SIS commands the same as you would if you were using the RS-232 link.

Connect to the ISM 824 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 ISM 824.
	If the switcher is password protected, Telnet displays the password prompt.
2.	If necessary, at the password prompt, type in your 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 ISM 824 switching capabilities and editing functions. Users can select video and/or audio for output, select test patterns, set RGB and audio mutes, select a blue screen, and view all settings with the exception of passwords. By default, the ISM 824 ships 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 ISM 824.

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 Ekey. 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, that returns you to the Telnet prompt while leaving the connection to the ISM 824 intact.

The Escape key is the Ekey on the computer keyboard.
