For the ocelot sending a 12 volt signal. That would be possible, the sell a multi port relay box that you can controll with Ocelot. So take an small power source, route it through the relay device and you are there.
The RS-232 bobcat is currently send only. I was told this had to do with the software level of the Ocelot, and that it might become 2 way in the future.
ADI sells also somethin like an sensor bobcat. That is a device which can sensen a LED is on or off. You could use that as well to sense the 568 is powered on or off i think. This is quite easy to program for a Ocelot.
