TWISTED PAIR ETHERNET WITH RJ-45 CONNECTOR
If you hold the RJ-45 connector facing you (as if you were going to plug it into your mouth) with the lock tab down, then the pins are numbered 1 to 8 from left to right. The pin usage is as follows:
Pin Number Assignment ---------- ---------- 8 Reserved for Telephone use 7 Reserved for Telephone use 6 Input Data (-) 5 Reserved for Telephone use 4 Reserved for Telephone use 3 Input Data (+) 2 Output Data (-) 1 Output Data (+)
* since it is best to think of the lock tab as always facing down, we put the above pin listing in descending order.
CLIP FACING DOWN - This is how I wire the connector on twisted pair ethernet: Three (3) and six (6) must be a twisted pair.
