I also started out with the digital version of Barry's book. Soon after I ordered the printed copy and have been buying/using those ever since. You can take them to the layout or where ever you need them and I just like the books better for reading as well. The digital copy is nice for finding things faster using the search. I now usually purchase both whe a new version comes out. Lots of good info in those books! The DCS video is good, I got it in 2011 or so, but it is a bit outdated now. The book is more current and Barry usually updates it as new features are added.
As John P explained above, I did the same as he says. One pair of wires from one TIU channel to each MTH terminal strip and from there as many pairs as I needed for my blocks being fed from that terminal strip.
