I shut the railroad down for a while over the past year and a half to make some changes. I have them completed and put my known, at the time, DCC equipped engine on the test track and get no response. The rear light comes on but that’s it. I’ve made a small change to the decoder program to see if the jmri decoder pro sees it. It writes to the decoder with no errors. Not sure where else to start looking. Any help would be appreciated. Thanks and hope all have managed to stay healthy.
