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
Notice how the pins are numbered in Figure 12. Be sure to hold the connectors
in the same orientation when connecting the wires to the pins.
Figure 12: Connector Pin Numbers
Each twisted-pair link segment must have a male connector attached to both
ends. According to the 10Base-T specification, pins 1 and 2 on the connector
are used for transmitting data; pins 3 and 6 are used for receiving data, as
shown in Table 4.

*The “+” and “-” signs are used to represent the polarity of the two wires that make up each wire
pair.
