Digitrax PR4 Interface DCC

James Ford

Does anyone know if the Digitrax PR4 Interface will program an engine that is equipped with a keep alive device? My club is replacing a DCC Specialties interface because our experience is it will not program an engine with keep alive.  The SoundTraxx PTB-100 will as a member has one, but we have a chance to get the PR4 as a donation.
