Default IP addresses
To access the MTPX Plus switcher via the LAN port, you need the unit’s IP address,
and may need the subnet mask and the gateway address. If the IP address has been
changed to an address comprised of words and characters, you can determine the
actual numeric IP address using the ping (ICMP) utility (see appendix A, “Ethernet
Connection”, for more details). If the addresses have not been changed, the factory-
specified defaults are:
• IP address 192.168.254.254 • Subnet mask 255.255.0.0
• Gateway address 0.0.0.0
Establishing a connection
Establish a network connection to an MTPX Plus 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.
N 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 five minutes but the value can be changed.
See the Configure port timeout SIS commands on page 4-26.
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
An MTPX Plus 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.
