Ethernet Link
The rear panel Ethernet connector on the MPX 866 A matrix switcher can be connected to
an Ethernet LAN or WAN. This connection makes SIS control of the switcher possible using a
computer connected to the same LAN.
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 (see figure 69).

Patch (straight-through) cable — Connection of the MPX 866 A matrix 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.
