I have a new MTH caboose with Operating Signal Man. Until it arrived I was un-aware of the detail issues in it's operation with DCS. I have a single loop layout powered by a single Lionel brick transformer (PH180) going to the DCS Variable channel 1. My only controller for DCS is the WIU and my iPhone running the DCS app. The only way I can figure out how to make the Signal Man to work is using the app on a Conventional Track. That is not acceptable for my interests.
Several on this forum have suggested one of the older "railsounds" buttons. I have one (6-5906). On the back of the button it says "designed for use with common ground wiring. It is not to be used with a Lionel 6-4690 Type MW transformer".
I understand transformer phasing. I'm not sure what the common ground comment is supposed to mean? Especially with a single transformer?
1. If I install this button between the PH180 transformer and the TIU channel 1 input can it harm the TIU when activated?
2. Could it harm the PH180?
3. Given I only have 1 transformer is this even relevant to my situation.
I have spent several hours on the forum archives and Google and I can't fine the answer. Help would be appreciated.
Thanks in advance.
