Connecting to the LAN Port
When connecting a computer to the DXP LAN port, it is essential that you use the correct
Ethernet cables, and that they be properly terminated with the correct pinout (see figure 4).
Ethernet links use Category (CAT) 3, 5e, or 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 the cables; this can cause transmission errors.
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 or pair assignments are swapped.
Both ends of the cable can be T568B (as shown)
or T568A (not shown).

RJ-45 Connector and Pinout Tables
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.
The Ethernet cable must be properly terminated for your application as either a crossover or
a straight-through cable.
•
Crossover cable
— Direct connection between the computer and the DXP switcher
•
Patch (straight-through) cable
— Connection of the DXP to a network via a network
switch
