LAN port — If desired, for IP control of the system, connect the
matrix switcher to a PC or to an Ethernet LAN via this RJ-45
connector. You can use a PC to control the networked switcher
with SIS commands from anywhere in the world. You can also
control the switcher from a PC that is either running Extron’s
Windows-based control program or that has downloaded HTML
pages from the switcher.
Ethernet connection indicators — The Link and Act LEDs indicate the status
of the Ethernet connection. The Link LED indicates that the switcher is
properly connected to an Ethernet LAN. This LED lights steadily. The Act
LED indicates transmission of data packets on the RJ-45 connector. This LED
flickers as the switcher communicates.
Cabling and RJ-45 connector wiring
It is vital that your Ethernet cables be the correct type cables, and that they be
properly terminated with the correct pinout. Ethernet links use Category (CAT) 3,
CAT 5e or CAT 6, unshielded twisted pair (UTP) or shielded twisted pair (STP)
cables, terminated with RJ-45 connectors. Ethernet cables are limited to a length of
328' (100 m).

Do not use standard telephone cables. Telephone cables will not support
Ethernet or Fast Ethernet.
Do not stretch or bend cables. Transmission errors can occur.
The cable used depends on your network speed. The switcher supports both
10 Mbps (10Base-T — Ethernet) and 100 Mbps (100Base-T — Fast Ethernet),
half-duplex and full-duplex, Ethernet connections.

• 100Base-TFastEthernetrequiresCAT5eUTPorSTPcableatminimum.
The Ethernet cable can be terminated as a straight-through cable or a crossover
cable and must be properly terminated for your application (figure 2-8).
• Crossover cable — Direct connection between the computer and the
matrix switcher.
•
Patch (straight) cable — Connection of the 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.
