Hudson 5432 - ok, I was talking about the powering of the switches, not the controlling of them. So basically, if I want to power all three legs of each switch, two or all three legs get powered by an independent power source that doesn't run through the TIU. That's ok given we don't want to operate them thru an AIU at this point. And if one leg is powered by the one power drop running to terminal block going to TIU, then I could control via AIU. Is that the idea?
