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 CrossPoint or MAV Plus 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
CrossPoint or MAV Plus 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
CrossPoint or MAV Plus switcher intact.
The Escape key is the <Esc> key on the computer keyboard.
Analog echo
Once connected to the CrossPoint or MAV Plus 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 analog_echo and then press <Enter> before you open the
connection to the switcher.
With analog 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 analog 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 analog
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 analog echo by typing unset analog_echo and then pressing <Enter> at
the Telnet prompt. If you are connected to the CrossPoint or MAV Plus switcher and need to
access the Telnet prompt to turn analog 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>.
