Cabling
It is vital that your Ethernet cables be the correct cable type and that they be properly
terminated with the correct pinout. Ethernet links use Category (CAT) 3, 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 10).
•
Crossover cable — Direct connection between the computer and the DMS matrix
switcher
•
Patch (straight) cable — Connection of the DMS 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 that is wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.
