There are two primary types of Cat5 wiring diagram schemes: straight-through and crossover, which determine how wire terminals are configured at each RJ45 connector on both ends of the cable.
- Straight-through Cat5 Wiring Diagram: Straight-through Cat5 wiring uses identical pinouts at both connectors, connecting wire pairs straight from one end to the other, enabling connectivity when a computer is directly linked to a network switch, router, or Ethernet wall port.
- Cross-over Cat5 Wiring Diagram: The crossover Cat5 wiring diagram swaps the transmit (Tx) wires on one connector with the receive (Rx) wires on another, reversing transmit and receive pairs between interfaces. This enables connectivity between like devices without a need for a central network device and is used to link two computers or switches directly.
In summary, the specific Cat5 wiring diagram is essential for configuring straight-through and crossover Cat5 cable connections.
