Figure A-1 show the PCI 10/100BaseTX RJ-45 Connector Pin Assignments

Note: The Pin assignments are identical for 10Base-T and 100Base-TX, by using UTP cable.

Network cabling

In Fast Ethernet 100Base-TX, the cable, quality, distance, and connectors must comply with the EIA/TIA 568 “Commercial Building Wiring Standard”.

IEEE 802.3u Specification: The 100Base-TX specification supports 100 Mbps transmission over two of four pairs of twisted Ethernet wiring. In two pair wiring, one pair of wires is used for transmission, and the second is used for collision detection and receiving.

Figure B-1 show the Unshielded Twisted Pair Wiring

Note: For the 10/100 Mbps twisted pair cable, pins 1&2 must be a pair and pins 3&6 must also be a pair. Each pin must connect straight to the other end of the
