Establishing a connection
Establish a network connection to a FOX 4G matrix switcher as follows:
1. Open a TCP socket to port 23 using the switcher's IP address.
N 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.
N 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 4-19.
N 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 FOX 4G matrix 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
stay low and unnecessary open sockets should be closed.
Using verbose mode
Telnet connections to a FOX 4G matrix 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 3. See the "Verbose
mode" SIS command on page 4-19. In verbose mode 3, the Telnet socket reports
changes in messages that resemble SIS command responses.
