Establishing an Ethernet Connection
Establish a network connection to the SMX as follows:
1.
Open a TCP socket to port 23 using the SMX IP address.
NOTE:
The SMX responds with a copyright message including the date, the name of the
product, firmware version, part number, and the current date/time.
NOTES:
2.
If the SMX is password-protected, enter the appropriate administrator or user password.
3.
If the password is accepted, the SMX responds with
Administrator
4.
If the password is not accepted, the
Connection Timeouts
The Ethernet link times out after a designated period of no communication. By default, this
timeout value is set at 5 minutes but the value can be changed (see the
IP port timeout
NOTE:
Number of Connections
An SMX can have up to 200 simultaneous TCP connections, including all http sockets
and Telnet connections. When the connection limit is reached, the SMX 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 stay low and unnecessary open sockets should be closed.
Using Verbose Mode
Telnet connections to the SMX 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 SMX, the Telnet session must be in
verbose mode 1 or 3 (see the
If the local system administrators have not changed the value, the factory-
specificed default, 192.168.254.254, is the correct value for this field.

Extron recommends leaving the default timeout at five minutes and periodically

idle periods, Extron recommends disconnecting the socket and reopening the
connection when another command must be sent.
