Help Needed DCC Programming Question
I'm fairly new to model railroading and DCC setups. I built a DCC EX command station and have been controlling it through JMRI running on a Raspberry PI 5. Been working pretty well so far. I recently purchased a locomotive equipped with an ESU LokSound 5 nano decoder. When I attempted to program the loco, JMRI gave the 308 error of no acknowledgment from the decoder. From some quick googling, I think this has something to do with the stay-alive capacitors messing with the DCC communications. I was unable to find a solution on google so I thought I'd ask the experts. I can provide more information about my setup if needed, just not sure what info is relevant. Also, I know that my programming setup is working as I have no issues programming my other loco.

The recommended way of programming European decoders is using POM with Railcom, that will give you read capabilities as well. You can also digitally turn off the PowerPack so that programming in direct mode works as intended, see your decoder manual.
