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.
