Cable Requirements
A.1 Ethernet Cable
A CAT 3~7 UTP (unshielded twisted pair) cable is typically used to connect the Ethernet device to the router. 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. ( Table A-1 )
