Extron electronic MPX 866 A Establishing a Connection, Connection Timeouts, Number of Connections

Establishing a Connection

Establish a network connection to a MPX 866 A switcher as follows:

1.Open a TCP socket using the IP address of the switcher.

NOTE: If the local system administrators have not changed the value, the factory- specified default, 192.168.254.254, is the correct value for this field.

The switcher responds with a copyright message including the date, the name of the product, firmware version, part number, and the current date/time.

NOTE: If the switcher is not password-protected, the device is ready to accept SIS

commands immediately after it sends the copyright message.

If the switcher is password-protected, a Password prompt appears below the copyright message.

2.If the switcher is password protected, enter the appropriate administrator or user 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 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 commands on page 73.

NOTE: Extron recommends leaving the default timeout at 5 minutes and periodically

issuing the Query (Q) command to keep the connection active. If there are long idle periods, Extron recommends disconnecting the socket and reopening the

connection when another command must be sent.

Number of Connections

A MPX 866 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 an IP Link device, the number of connections should be kept low and unnecessary open sockets should be closed.

Using Verbose Mode

Telnet connections to a MPX 866 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 “Verbose mode” SIS command on page 73.
