Ethernet (LAN) Port
The rear panel Ethernet connector on the switcher can be connected to an Ethernet
LAN or WAN. Communication between the switcher and the controlling device is
via telnet (a TCP socket using port 23). The TCP port can be changed if necessary,
via SIS. This connection makes SIS control of the switcher possible using a
computer connected to the same LAN or WAN. The SIS commands and the actions
of the switcher are identical to the commands and actions the switcher has when
the computer is communicating with it via a serial port.
Ethernet connection
The Ethernet cable can be terminated as a straight-through cable or a crossover
cable and must be properly terminated for your application (figure 4-3).
• Crossover cable — Direct connection between the computer and the
CrossPoint 450 Plus or MAV Plus switcher
• Patch (straight-through) cable — CrossPoint 450 Plus or MAV Plus switcher
to an Ethernet LAN
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.

Default IP addresses
To access the CrossPoint 450 Plus or MAV Plus switcher via the LAN port, you need
the Extron 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 • DHCP: off
