An Ethernet twisted pair link segment calls for two pairs of
wires, with each pair differentiated by color. Each twisted
pair link segment must have an RJ-45 male connector
attached to both ends. Pins 1 and 2 on the RJ-45 connector
are for transmitting data while pins 3 and 6 are for receiving
data. See chart below:

1 Tx+ 1 Rx+
2 Tx- 2 Rx-
3 Rx+ 3 Tx+
6 Rx- 6 Tx-
* The “+” and “-” signs are used to represent the polarity of
the two wires that make up each wire pair.
