ETHERNET CABLING
This diagram shows the pinout for standard unshielded
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.
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
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.
