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 repeater or other device
in between; and to cascade repeaters or switches that don’t have uplink ports.

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 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
