I love this post. Some of us struggle with compatibility between MTH DCS and Legacy ,,,,, i have both and for the love of me, still dont "get" why there are four inputs and four outputs ... and why the transformer post #1 has to be on
I have four separate loops like @ CurtisH but when i plug loop two into the TIU i am still controlling it from lever one on the transformer
I bought Barry's book, but i am lost ... i am sure that i will figure it out with time
