Mike,
Thanks for your response. Sorry about the lack of information.
MTH DCS TIU system. When I purchased it I was under the impression I could run MTH Locomotives,TMCC equipped locomotives and conventional locomotives.
I am powered by a Postwar ZW which runs my TMCC just fine.
I walked away from the MTH DCS system a few ago because it would just never work. As I said previously very frustrating. I even bought the DCS companion from Barry a few years ago to no avail.
I understand most have upgraded to smart phone applications and I am behind the technology but I decided to try again to get this **** thing working.
