To everyone on my post... I am so sorry that I never responded back to your answer to my problem. DCC Loop Problem dated back in March 15, 2020. I was new to this Forum back then [in fact any Forum] and I'm not sure how to set up to get responses to me in my Email. I will investigate this and try to fix it so I will receive responses. When next I have a question or a problem. I think I fixed it, so respond if you would like. I would like to here from you all. Thank you Fuzzy49

Well here go's... First, I am a new member and new to DCC. I have a Roco z21 White system as a starter set, just to get to know the way DCC works. To me at this point it is very "Confusing". But I am learning as I go. Now I need to know...I made a sample LOOP track [see picture] and when I move the engine from the main track around the Loop and back onto the main track going the other way the engine reverses and stops. I am using an ATLAS INSULFROG Turnout [without their point motor]. How then do I wire up the Cobalt IP Digital so it can change the polarity when I exit the Loop? Cobalt Digital IP point motor to the Turnout using a Red and Black wire to connect to the Buss Line to power it, this I got so far. But where do I hook up the Green Frog wire to the Turnout and Cobalt so it can switch the polarity of the track? The turnout has an insulated Frog. Or is there some other way to achieve this? I was told that for a return loop you would need to use an auto revers-er, connected to the loop this changes the polarity automatically. But what is the best choice and most reasonable for a system? I don't want to go broke doing this. I will be expanding my layout too. Not quit sure just how big yet. My old DC system was two 4' x 8' a 3' x 2' a 8' x 2' and a 8' x 6' sections in my basement. I do have it listed on Craigs list, but if I can't get rid of it then I will re-do the whole set up to DCC.
