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
Fiber Matrix switcher via Telnet.
Open
Connect to the Fiber 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 link.
Connect to the Fiber 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 Fiber Matrix.
If the switcher is password protected , Telnet displays the password prompt.
2 . If necessary, at the password prompt, type {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 Fiber Matrix switching
capabilities and editing functions. Users can create ties, set mutes, and view
all settings with the exception of passwords. By default, the Fiber Matrix
switcher 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 Fiber 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 E 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, that returns you to the Telnet prompt while leaving the
connection to the Fiber Matrix switcher intact.
The Escape key is the
E key on the computer keyboard.
Local echo
Once connected to the Fiber 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 switcher’s responses 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 Fiber Matrix switcher and
need to access the Telnet prompt to turn local echo off, type the Escape character
(
Ctrl
+
]
).
