Ethernet (LAN) Port
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application (see “Ethernet Connection“ in the
“Installation” section).
• Crossover cable — Direct connection between the computer and the MTPX Plus
switcher.
• Patch (straight-through) cable — Connection of the MTPX Plus switcher to an
Ethernet LAN.
Default IP addresses
To access the MTPX Plus switcher via the LAN port, you need the IP address for the unit, 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 “Ethernet Link” on page 146 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 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.
NOTES: • 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 five minutes but the value can be changed. See the
Configure port timeout SIS commands on page 95.
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.
