The Cross-Over CAT5 Cable is a specialized networking cable that facilitates direct communication between two devices of the same type. Unlike regular straight-through cables, which connect different devices (like a computer to a router), the cross-over cable swaps the transmit (TX) and receive (RX) pins at one end.
In a cross-over cable, the TX pin on one end is connected to the RX pin on the other end, and vice versa. This clever arrangement allows two devices to talk directly to each other without any intermediary network equipment.
