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 FOX 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 FOX 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
FOX matrix switcher intact.
The Escape key is the <Esc> key on the computer keyboard.
Local echo
Once connected to the FOX 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 FOX matrix switcher and need to access the
Telnet prompt to turn local echo off, type the Escape character (<Ctrl>+<]>).
Set carriage return-line feed
Unless commanded otherwise, Telnet transmits a line feed character only (no carriage
return) to the connected switcher when you press the <Enter> key. This is the correct
setting for SIS communication with the switcher. The Telnet set crlf command forces
Telnet to transmit carriage return and line feed characters when <Enter> is pressed, but if
crlf is set, the SIS link with the switcher does not function properly.
Close
To close the link to the switcher, access the Telnet prompt by typing the Escape character
(<Ctrl>+<]>). At the Telnet prompt, type close, and then press <Enter>.

For Telnet command definitions, at the Telnet prompt, type ? and then press <Enter>.
