So if you are connecting similar devices and you only have a straight-through cable, you can use it. It's important to have a good understanding of color-coding schemes in crossover and straight-through cable but today almost all networking devices support Auto-MDIX, by which devices can automatically detect which cable is required and switch to it automatically. It's named crossover cable since wires are cross-connected at both ends of RJ-45 connectorsĪutomatic Medium-Dependent Interface Crossover (Auto-MDIX) To sum up pin 1 and 2 from device A is connected to pin 3and 6 of device B, while pin 3 and 6 of device A are connected to pin 1 and 2 of device B. It follows that pin 1 should be connected to pin 3, which is in receiving mode. As pin 1 is transmitting so it cannot be connected to pin 1 at the other end since that too is transmission mode. In Fast Ethernet pin 1 and 2 of the RJ-45 connector are reserved for transmission while pin 3 and 6 of the RJ-45 connector are reserved for receiving. Why to Use different oF crossover cable color codingĪs in UTP, there are eight wires twisted together in four pairs. This is different than straight through cable in which both ends of the cable must have the same color-coding standard at both ends, look for a Straight cable color code.
