C.1.2 Wiring Conventions
For Ethernet connections, a twisted-pair cable must have two pair s of wires. Each wire pair is
identified by two different colors. For example, one wire m ight be red and the other, red with
white stripes. Also, an RJ-45 connector must be attached to bot h 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.
