Hate to rain on your parade, but I have a friend who experienced exactly the same symptoms. He sent his PR4 back to DT, where it was for quite? long while due to the hurricane, but they finally sent it back saying they could not find anything wrong with it. There are some who claim that it DOES work, although I suspect they may be using it in the connected mode and programming through a DCS base station. Another person on the forum insists that there is no difference for JMRI between a PR3 and the PR4. However, for my friend, we were able to program normally using my PR3, but as soon as we replaced it with his PR4 we were not able to program. So something is different in that hardware.
DT will say that they do not support JMRI and their testing is using the DT SoundLoader software. It would be nice if one of the JMRI gurus in the forum could look into this problem, perhaps give those experiencing issues some instructions on capturing logging data to see what is going wrong.
