Wiring Conventions
For Ethernet connections, a twisted-pair cable must have two pairs of wires.
Each wire pair is identified by two different colors. For example, one wire
might be red and the other, red with white stripes. Also, an RJ-45 connector
must be attached to both ends of the cable.
Each wire pair must be attached to the RJ-45 connectors in a specific
orientation. The following figure illustrates how the pins on an Ethernet RJ-45
connector are numbered. Be sure to hold the connectors in the same
orientation when attaching the wires to the pins.

Ethernet connections, use only twisted-pair cables with RJ-45
connectors that conform to FCC standards.
