always made with the audio redirected. In such an operation, the switcher automtatically ties the audo to an output in the
computer/audio outputs group (outputs 1 through 6) as follows:
� If video is tied to output 7, audio is tied to output 1. � If video is tied to output 10, audio is tied to output 4.
� If video is tied to output 8, audio is tied to output 2. � If video is tied to output 11, audio is tied to output 5.
� If video is tied to output 9, audio is tied to output 3. � If video is tied to output 12, audio is tied to output 6.

Command/Response Table for SIS Commands
Connection timeouts
The Ethernet link times out and disconnects after a designated period
of time of no communications. By default, this timeout value is set
to 5 minutes but the value can be changed (see the Configure port
timeout SIS command on page 21).
NOTE: 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 the
performance of your switcher, keep the number of connections low
and close unnecessary open sockets.
Verbose mode
Telnet connections to a switcher can be used to monitor for 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 1 or 3 (see the Set verbose mode SIS
command on page 21). In verbose mode 3, the Telnet socket reports
changes using messages that resemble SIS command responses.
Host-to-Switcher instructions
The switcher accepts SIS commands through its serial port, its USB
port, or its LAN port. SIS commands consist of one or more characters
per command field. 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.
NOTE: The table that begins on the next page is a partial list
of SIS commands. For a complete listing, refer to the
