There are only two likely situationsthat would require a crossover cable: to connect two RAVE devices directly, without a repeater or other devicein between; and to cascade repeaters or switches that don’t have uplink ports.RJ-45 pinout for an Ethernetcrossover cableThe wire in UTP cabling is twisted together in pairs. Rather than randomly choosing a wiring scheme for thenetworking cable, it is important to have the RX wires in one pair and the TX wires in another pair, especially inlonger cable runs.AppendixRS-232 PORT INFORMATIONPin assignments of 9-pin female D connector:Pin 2: TX outPin 3: RX inPin 5: GroundPins 1 (DCD), 4 (DSR), and 6 (DTR) are tied together.
