Will have to buy a module though to get ATO going.
The breakout box was hard to find. I emailed every supplier on Neptune's website to find it. This was within the past 2 weeks, so maybe they've made up some more since then.
Personally... the snaps to plug wires into the BObox are pretty flimzy. If I was more patient (and I really wanted the ATO functional right away after hooking up the Apex), I would have built my own using the various instructions on the neptune forum here rather than buy one. I don't think I'd have saved that much money building my own... but the build quality would have been much better. Just thought I'd throw it out there.
