I have been trying to wire both tmcc-dcs using bpc's and tpc not an easy task for me!
but I have figured it out and thought I'd share my findings with all here. I have 6 bpc's that need power to inner and outer loops, now on the tiu set all 4 channels to fixed then connect channels 1&2 inputs together same for channels 3&4.
on output side of tiu run channel 1's power to first bpc to t-1 then use a jumper connecting it to t-2 on the first bpc, now connect channel 2 power to t-2 on second bpc and jumper to t-2 on the second bpc and so on. I know it's confusing but trust me it works and my signal strength is 10's all around and I also have a tmcc and legacy engine running on outer loop at same time no signal problems or commands not working I ran this for an hour worked flawlessly. if I could figure out how to post a diagram without it being so small you need a mega magnifying glass to see it I would.
hope this helps those that want both and still be able to use tpc's to run conventional too.

CB&Q,
Thank You for your valuable information.
I had not seen any of your posts lately, so I figured you were busy for Christmas and Little Christmas, making and delivering the goodies.
Thank You, for taking the gift orders, from my wife and family and delivering them to me of more 'Train Goodies.'
Merry Christmas, Healthy, Happy New Year, Merry Little Christmas and a Healthy, Happy Little New Year,
Ralph
