Appendix A: Cable Requirements
A CAT 3,4 or 5 UTP (unshielded twisted pair) cable is typically used
To connect the Ethernet device to the converter.
A 10Base-T cable often consists of four pairs of wires, two of which are
used for transmission. The connector at the end of the 10Base-T cable is
referred to as an RJ-45 connector and it consists of eight pins.
The Ethernet standard uses pins 1,2,3 and 6 for data transmission
purposes.
