Ethernet crossover cable pinout


Do you need to connect two computers directly without a switch or router? Then, you need an Ethernet crossover cable. It enables two devices to communicate directly, without the need for an intermediary device.


What is an Ethernet Crossover Cable?


An Ethernet crossover cable is a type of cable that connects two devices of the same type. It swaps the transmit and receive wires in the cable, allowing the two devices to exchange data. An Ethernet crossover cable looks similar to a regular Ethernet cable, but the internal wiring is different.


Pinout of an Ethernet Crossover Cable


The pinout of an Ethernet crossover cable is different from a standard Ethernet cable. On one end of the cable, the transmit pins are connected to the receive pins on the other end, and vice versa. The pinout of an Ethernet crossover cable is as follows:



  • Pin 1: Transmit + (TD+)

  • Pin 2: Transmit - (TD-)

  • Pin 3: Receive + (RD+)

  • Pin 4: Not Used

  • Pin 5: Not Used

  • Pin 6: Receive - (RD-)

  • Pin 7: Not Used

  • Pin 8: Not Used


It's important to note that not all Ethernet devices support crossover cables. Most newer devices have automatic crossover detection, allowing them to work with either a straight-through or crossover cable. However, if you're having trouble connecting two devices directly, try using an Ethernet crossover cable to see if that solves the problem.
