Selected SIS™ Commands
You can use Simple Instruction Set (SIS) commands for operation and configuration of the switchers. You can run these commands from a PC connected to a serial port (i, j, and m on pages
Establishing a network (Ethernet) connection
NIf you connect to the switcher via the LAN port, and it is the first time you have done so, you may change the default settings (IP address, subnet mask, and [optional] administrator name and password) of the controller. See "Configuring for Network Communication" on page
Establish a network connection as follows:
1. Open a TCP socket to port 23 using the IP address of the switcher.
NThe factory default IP address is 192.168.254.254.
The switcher responds with a copyright message including the date, the name of the product, firmware version, part number, and the current date and time.
NIf the switcher is not
NIf the switcher is
2. If the switcher is
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 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
NExtron 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, 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
Establishing a USB port connection
A standard USB cable and the Extron DataViewer utility, version
2.0or newer, can be used for connection to the MTPX Plus 128 Configuration port. The USB cable, available at any local electronics store, should be terminated on one end with a mini USB B male connector
NBefore 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 7.7 or newer of the Matrix Switchers Control Program and then run the Found New Hardware Wizard. See “Installing the program,“ on page
Host-to-switcher instructions
The switcher accepts SIS commands through either serial port, the USB port, or the 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.
NThe table that begins on the next page is a partial list of SIS commands. For a complete listing, refer to the MTPX Plus User's Manual.
