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 33).
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 33). In verbose mode 3, the Telnet socket reports
changes using messages that resemble SIS command responses.
Establishing a USB Port Connection
A standard USB cable and the Extron DataViewer utility, version 2.0 or
newer, can be used for connection to the MTPX Plus matrix switcher
Configuration port. The USB cable, available at any local electronics
store, should be terminated on one end with a mini USB B male
connector
NOTE: Before you use the USB port for the first time, install the
USB driver on your computer. The simplest way to do this
is to install version 8.0 or newer of the Matrix Switchers
Control Program and then run the Found New Hardware
Wizard. See "
Installing the Program " on page 34 and
" First-time Connection Considerations " on page 35.
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, see the
MTPX Plus 6400 Series User Guide.
