hello everyone. I am wondering if anyone knows how to program an MTH HO engine with JMRI via digitrax. I have a PR3 that is connected to a DCS 50. the PR3 is in the MS100 mode and the DC50 is connected via Rail A/B to the track. I understand that MTH needs to be programmed on the main but not sure how to configure JMRI and the hardware to do that. I tried selecting POM with JMRI but the proto3 is not responding to jmri. any thoughts would be appreciated.
