<DIV><FONT face=Calibri>Having used and developed systems with X10 power line
systems, here is a little input. In North America house power is divided in two,
signals on the same half (phase) generally work well but suffer from poor
connections at plugs and switches. When crossing phases without any cross
over hardware the signal must travel to the nearest outside transformer and
may even be interfered with by a neighbor with similar equipment. Cross
over capacitors as advised must be carefully installed to be effective (they are
often disguised in a black box type of connection). The biggest issue is
however brown outs and power surges. Most homes have no protection (whole home
isolation) from the outside world, this would involve a transformer for each
house. This means that most equipment is vulnerable to power surges. Placing an
inline surge protector will interfere with any signals on the power line.
X10 switches (the lower cost non-commercial type) seem to die after
a few years.</FONT></DIV>

<DIV><FONT face=Calibri>So yes you can make this type of connection work, but
you are taking a chance with your equipment. Possibly some of the more expensive
equipment may have built in protection. If you have a forced Air ducting system
you can buy cat 6 cable that is designed to run in duct work and can be safely
installed in the return air duct work in your home. This is an effective route
for retrofitting Ethernet cable since the power on the cable is low wattage
and there is always a route from lower to upper floors, Attics and Basements are
often accessible from the return air duct work.</FONT></DIV>
