Figure 6-11. Ethernet Cable Construction

To make a straight Ethernet cable, perform the following steps (see Figure 6-11).

Follow standard practices for Ethernet connections.

Use RJ45 connectors.

Use cable rated for Category 3 (CAT3) or better.

Use straight cable wiring, with identical pin connections on both plug ends.

Use twisted pair wires for receive pair and transmit pair.

Use continuity tester to verify pin connections.
