Step 2. Network Cable
Connections
Before connecting a network cable to the DE-528CT adapter, ascertain that
the network cable medium is
Twisted-Pair
1
or
Thin Coaxial

cable. Then refer to one of the two sections following, according to your
network cable type.
Twisted-Pair Cable
Ascertain that you have a straight

twisted-pair cable, UTP cable (Cat. 3 ,4 ,5)
or EIA/TIA-568 non-standard 100-ohm STP cable, not more than 100 meters
(328 feet) in length for the network connection. The cable will have an RJ-45
plug on each end. The stations are connected in a star topology.

Twisted Pair (TP) cable features RJ-45 connectors, and is available with or without EM
shield. TP cable without EM shield is also known as 10BaseT cable or UTP (Unshielded
Twisted-Pair) cable. TP cable with EM shield is known as screened twisted-pair cable, and
the EM shield may be either an aluminum sheath or a copper braid enclosing the twisted-pair
bundle.

Thin Coaxial
features BNC connectors and is known by a variety of other names,
including 10Base2 cable, BNC cable, and RG-58 cable.

Pins 1 and 2 must be a pair (the connected wires must be a twisted pair in the cable makeup)
and pins 3 and 6 must be a pair. Each pin must connect straight through the cable (that is pin
1 through to pin 1 of the opposite connector, pin 2 to pin 2, pin 3 to pin 3, and pin 6 to pin 6;
pins 4, 5, 7, 8 are not used).
