I am getting ready to hook up my DCS remote. We have read that we can take the TIU and plug in an optional aux. power supply of 18V 1 AMP and not run the transformer thru the TIU. I will be operating two separate loops on my layout split by my #8 Ross Crossover. Power will come from my Z4000 Track One and Track Two. Now there is talk about the use of the TIU for this installation, but do I need two TIUs to be able to run from one loop to the other loop? It sounds like I can use the remote on "Super TIU" to accomplish this; but do I need two TIUs. We are thinking one TIU and use the two outputs numbered one and two. So are fixed voltage separate from one another? If you used two TIUs would they just be fighting eachother?
Thanks for your help!
