Some info on this subject in the below link. Scroll down a ways. Store the link in Favorites if using IE or Bookmarks if using FF. You will need it. I say that a lot because I see some who have no idea on how to do that, They click on a link but depend on the History in their PC to find the link again and sometimes find out they deleted the History. Argh.
There is a LOT of useful DCC wiring in the link.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
