Straight-Through
OR
Crossover Twisted-Pair cable may be used.
Shielded Twisted-Pair (STP)
OR
Unshielded Twisted-Pair (UTP) may be used.
Pins 1&2 and 3&6 are the two active pairs in an Ethernet network.
RJ-45 Pin-out: Pin 1 = TD+, Pin 2 = TD-, Pin 3 = RD+, Pin 6 = RD-
Use only dedicated wire pairs for the active pins:
(e.g., blue/white & white/blue, orange/white & white/orange, etc.)
Do not use flat or silver satin wire.
