I use a Pricom Design "Layout Lighting Solution" (LLS) board as a DCC/DMX gateway. It connects directly to the DCC bus and translates turnout commands from JMRI to control DMX devices. It has an Ethernet web server where you configure the lighting scenes (dimming rate). I have panels in panel pro that control the whole mess. I divide the 24 hour day into 12 scenes and a Jython script automates the sequence. See attached. I'd be happy to share all the software/coding. You can probably get Bob at Pricom to come down on the price of the LLS. He is asking like $700 (yes, $700) but he gave me one for free (yes, free). This approach works very well for my needs. -- Vinny DeRobertis ~ Apex, NC New York & Hudson Valley RR
