RE: [ECS] ECS X-10 Interface... Devlin Tue, 5 Jan 1999 03:15:54 -0800

I actually have an Ethernet connection from my computer and hub to my kids
computer, which is right next to where I would want to put the HV box.  So I
could put another hub at my kids computer and connect it to the HV box. Can
you easily use ECS to work with the HV box over a LAN?  Can you connect HV
to a LAN?

Thanks,
Jim Devlin

I'm not sure what kind of connection Home Vision uses - is it serial? If it
is, I believe 150 feet is still within the specifications of a regular
RS232 - I'm not positive, though. Furthermore, not all serial ports provide
the necessary voltage that the RS232 specification calls for. Nowadays,
it's almost unusual to have the full + and - 12 volts. Twisted pair will
probably work. It wasn't invented for serial-port use, but nowadays is
fairly commonly used for that purpose. So, bottom line, my *guess* is that
150 feet should work, but you won't know for sure until you try it.

You CANNOT use a LAN hub unless you have an actual LAN connection; hubs
only work if traffic occurs at the specified 10 MBit per second. They have
some circuitry in them that relies on this.
