Ethernet Connection
NOTE: This port and TP cable carries control signals, not the video, audio, serial signals
carried by the RJ-45 (item
a
).
k LAN port — If desired, for IP control of the switcher, connect the 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 running the Extron
Matrix Switchers Control Program or has downloaded HTML pages from
the switcher.
Ethernet connection indicators — The Link and Activity LEDs indicate
the status of the Ethernet connection. The Link LED indicates that the
switcher is properly connected to an Ethernet LAN. This LED should light
steadily. The Activity LED indicates transmission of data packets on the
RJ-45 connector. This LED should flicker as the switcher communicates.
Cabling
It is vital that your Ethernet cables be the correct cable type, and that they be properly
terminated. Ethernet links use Category (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 feet (100 m).
NOTES: • Do not use standard telephone cables. Telephone cables do 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.
• 10Base-T Ethernet requires CAT 3 UTP or STP cable at minimum.
• 100Base-T Fast Ethernet requires CAT 5e UTP or STP cable at minimum.
RJ-45 connector wiring
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 13).
• Crossover cable — Direct connection between the computer and the switcher
• Patch (straight) cable — Connection of the MTPX 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 that is wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.
