a. Pins 4, 5, 7, and 8 are tied to termination resistors on the Control. Standard
Ethernet cables contain 8 wires. The Control only uses 4 of these wires as
shown. Connecting the 4 unused wires to pins 4, 5, 7, and 8, (as will be done in
a standard Ethernet cable) reduces noise that can be induced from the unused
wires to the Transmit and Receive wires.
