A.3 10BASE-T PIN ASSIGNMENTS

An Ethernet twisted-pair link segment requires two pairs of wires.

Each wire pair is identiﬁed by solid and striped colored wires. For

example, one wire in the pair might be red and the other wire, red

with white stripes.

Connectors

Refer to the diagram below and note how the pins are numbered.

Be sure to hold the connectors in the same orientation when

connecting the wires to the pins.
