Network Wiring
Network wiring is no different than simple wiring, except that all units
are wired together in a "daisy-chain". The EOL jumper must be
enabled on the last unit in the chain.

Power and communication wires are connected from one unit to the
next unit in the "chain", as illustrated in the drawing: the wires come in
to the unit from the "previous" unit and can be wired from that unit to the
"next" until the network is complete.
LON (TP/FT10) communication connections are not polarity sensitive.
Please consult the Echelon documentation for further LON connection
details (http://www.echelon.com/support/documentation/manuals/
routers/078-0167-01B.pdf).
