10BASE-T/100BASE-TX Pin Assignments

With 10BASE-T/100BASE-TX cable, pins 1 and 2 are used for

transmitting data, and pins 3 and 6 for receiving data. The “+” and

“-” signs in the tables below are used to represent the polarity of

the wires that make up each wire pair.

ports has an internal crossover, the two pairs of wires must be

straight-through.
