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.
1000BASE-T Pin Assignments
The table below shows the 1000Base-T pinouts for a
straight-through cable connection. These ports require that all four
pairs of wires be connected. Note that for 1000Base-T operation, all
four pairs of wires are used for both transmit and receive.
