Hi Group,
I watched this interesting thread and noticed that none of you recalled the
susceptibility of the system.
We had severe problems with susceptibility of computers with Ethernet coax
connection. As a matter of fact did not find any computer meeting the
requirements for industrial

Ken,
It is a potential shock hazard if the coax run is long and runs from
building to building (for instance) where the ground potentials may be
different in the different buildings. One can develop

If all the ac equipment is powered by the same local source, and all the ac
