Connecting to the DXP (Open command)
Connect to the DXP switcher using the
Open
command. After 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 DXP as follows:
1.
At the Telnet prompt, enter
open
IP
address
.
•
If the switcher is not password-protected
, no further prompts are displayed
until you disconnect from the DXP switcher.
•
If the switcher is password-protected
, Telnet displays the password prompt.
2.
If necessary, enter the password at the password prompt.
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 DXP switching
capabilities and editing functions.
•
Users can select test patterns, mute or unmute the output, select a blue screen,
and view all settings with the exception of passwords. By default, the switcher is
delivered with both passwords set to “carriage return.”
When you are logged in, the switcher returns either
Login
Administrator
or
Login
User
. No further prompts are displayed until you disconnect from the DXP switcher.
Escape character and Esc key
Many SIS commands include the keyboard <Esc> key. Consequently, some confusion may
exist between the
Escape
character and the <Esc> key.
When Telnet is first started, the utility advises that the
Escape
character
is
“
Ctrl+]
.” This
means that the Telnet
Escape
character is a key combination: the <Ctrl> key and the
<]>
key pressed simultaneously. Pressing these keys displays the Telnet prompt while leaving
the connection to the DXP switcher intact.
Local echo
Once your computer is connected to the DXP switcher, by default Telnet does not display
your keystrokes on the screen. SIS commands are entered blindly, and only the SIS
responses are displayed on the screen. To command Telnet to show all keystrokes, enter
set
local_echo
at the Telnet prompt before you open the connection to the switcher.
With local echo turned on, keystrokes and the switcher responses are displayed on the
same line.
Example:
1*1!In1
Out1
All
,
where
1*1!
is the SIS command and
In1
Out1
All
is the response.
Note that 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.
Local echo can be turned off by entering
unset
local_echo
at the Telnet prompt. If your
computer is connected to the DXP switcher, and you need to access the Telnet prompt to
turn local echo off, enter the
Escape
sequence (<Ctrl + ]
>
).
