Cable Requirements
Cable requirements for Adaptec DuraLAN NICs vary according to
network speed, cabling standard, and the connector to be used. The
table below identifies appropriate cabling, based on these
variables. The table applies to both Half Duplex and Full Duplex
(for selected models) environments.
Straight-through Cables
The majority of twisted-pair environments use twisted-pair cables
that are wired straight-through. This means that each pin of the
modular plug connector is wired to the same pin on the opposite
end of the cable (pin 1 is wired to pin 1). Straight-through cables
connect workstations and servers to repeaters and switches. Cables
for 100BaseTX use two pairs (pins 1, 2, 3, and 6).
