Selected SIS Commands
The switchers have Simple Instruction Set (SIS
™
) commands that
you can use for operation and conguration. You can run these
commands from a PC connected to either of the switcher’s serial
ports or the Ethernet port. See
b
,
c
, and
g
, on pages 2-5 and
2-6, for connection information.
Establishing a network (Ethernet) connection
Establish a network connection as follows:
1. Open a TCP socket to port 23 using the switcher’s IP
address.
N
The factory default IP address is 192.168.254.254.
The switcher responds with a copyright message including
the date, the name of the product, the rmware version,
the part number, and the current date/time.
N
If the switcher is not password-protected, the device is now
ready to accept SIS commands.
If the switcher is password-protected, the Password
prompt appears.
2. If necessary, enter the appropriate password.
If the password is accepted, the switcher responds with
Login User or Login Administrator.
If the password is not accepted, the Password prompt
reappears.
Connection timeouts
The Ethernet link times out and disconnects after a designated
period of no communications. By default, this timeout value
is set to 5 minutes, but the value can be changed. See the
Configure current port timeout or Configure
global IP port timeout
SIS commands on page 3-7.
N
Extron recommends leaving the default timeout at
5 minutes and periodically issuing the Query (Q)
command to keep the connection active or disconnecting
the socket and reopening the connection when necessary.
Number of connections
A switcher can have up to 200 simultaneous TCP connections,
including all HTTP sockets and Telnet connections. When
the connection limit is reached, the switcher accepts no new
connections until some have been closed. No error message or
indication is given that the connection limit has been reached.
To maximize performance of your switcher, the number of
connections should stay low and unnecessary open sockets
should be closed.
Verbose mode
Telnet connections to a switcher can be used to monitor changes
that occur on the switcher, such as front panel operations and
SIS commands from other Telnet sockets or a serial port. For
a Telnet session to receive change notices from the switcher,
the Telnet session must be in verbose mode 3. See the Set
verbose mode
command on page 3-7. In verbose mode 3,
the Telnet socket reports changes in messages that resemble SIS
command responses.
Host-to-switcher instructions
The switcher accepts SIS commands through either serial port.
SIS commands consist of one or more characters per command
eld. They do not require any special characters to begin or
end the command character sequence. Each switcher response
to an SIS command ends with a carriage return and a line feed
(CR/LF =
]
), which signals the end of the response character
string. A string is one or more characters.
N
The table that begins on the next page is a partial list
of SIS commands. For a complete listing, refer to the
