Article #360 - What pins are used for Ethernet connection?
Updated:03-09-2006 - Views: 217
Ethernet uses 4 pairs of wires, defined as follows:
1 & 2 Send and recieve
4 & 5 Send and recieve
3 & 6 Termination
7 & 8 Termination

Ethernet connection and communication can exist without the two pair of termination connections but we recommend all eight wires be used.
