ISM 482 Integrated Scaling Matrix Switcher • Programming Guide 32
Ethernet Link
The rear panel Ethernet connector on the switcher can be connected to the an Ethernet
LAN or WAN (see figure 27). This connection makes SIS control of the switcher possible
using a computer connected to the same LAN or WAN.
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 that is wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.

Ethernet Connection
The cable can be terminated as either a patch cable or a crossover cable (see figure 27) and
must be properly terminated for your application:
• Patch (straight) cable — Connection of the ISM to an Ethernet hub, router, or
switcher that also hosts a controlling computer
• Crossover cable — Direct connection between the ISM and a computer
Default Address
To access the switcher via the Ethernet port, you need the switcher’s IP address. If the
address has been changed to an address comprised of words and characters, the
actual
numeric IP address can be determined using the front panel (see IP Information on
page27) or the Ping utility (see
Pinging to Determine the Switcher IP Address or Ping
to determine the Web IP address on page 70 for more details). If the address has not
been changed, the factory-specified default is 192.168.254.254.
