If you're having the typical issue of Digitrax accessory decoders not working after the bus has been shorted (and perhaps you tried to send them a command while it was shorted), they just lost their programming. Program their address again, and they'll be fine. Pain in the a$$, but a cheap, if temporary, fix. My layout-in-progress is small enough (HCD) that I can reach all of my switches okay. But I am considering eventually controlling them through JMRI via DCC or LCC.
Thanks Andy i have not tried to reprogram yet. ive been heavily involved in building a portable self contained command station for my test track. im still waiting on motor shields and the nce switch kat to arrive plus some other odds and ends. I think im gunna wait till i get the switch kat before i reprogram that turn out then test the switch kat at that time.
