Remote Control
Selected SIS Commands
The switchers have Simple Instruction Set (SIS™) commands that you can use for operation and configuration. 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
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.
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, the firmware version, the part number, and the current date/time.
NIf the switcher is not
If the switcher is
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
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, 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
Host-to-switcher instructions
The switcher accepts SIS commands through either serial 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.
