ETHERNET CABLING
This diagram shows the pinout for standard unshielded twisted-pair (UTP) network cable. Both ends of the cable
are wired identically.
A crossover cable has the RX and TX wire pairs switched around at one end. There are only two likely situations
that would require a crossover cable: to connect two RAVE devices directly, without a hub or other device in
between; and to cascade hubs that don’t have uplink ports.

RJ-45 pinout for an Ethernet
crossover cable
The wire in UTP cabling is twisted together in pairs. Rather than randomly choosing a wiring scheme for the
networking cable, it is important to have the RX wires in one pair and the TX wires in another pair, especially
in longer cable runs.

Pin assignments of 9-pid female D connector:
Pin 2: TX out
Pin 3: RX in
Pin 5: Ground
Pins 1 (DCD), 4 (DSR), and 6 (DTR) are tied together. Pins 7 (RTS) and 8 (CTS) are also tied together. DCE (receives
on TD) operation; parity bit not checked.
