Yes to all of the a fore mentioned questions. This morning with first one, then two, then three MTH engines all reset to address (0) sitting the longest distance from the power source on the layout. With the DCS-RC connected passively to the track and applying power, all three remained dark and silent. When the startup command was sent out all three woke up, and when commanded to blow their whistles they did, when commanded to move they all moved in a very bad looking consist. When commanded to shut down, they all did. I would say at this point I do have a working test bed with both the DCS-RC and the full DCS-TIU systems.
I even checked that with the very bad consist running around the loop of track, I could also fire up a Legacy TMCC engine on a siding connected to the same loop.
How much time does it take from the application of power to the DCS-RC to the start of the watchdog burst?
I am ready for the boards to return from their vacation out east.
