DCC Update - from System/1 to NCE
Installing the new system was easy and so far everything seems to be working fine. I did have to reset several of my locomotive decoders back to factory default and re program them. I use a SPROG 2 to record all the settings but given the previous systems were set using 23 volts, I played it safe and re programmed all decoders and recorded them on DecoderPro. DecoderPro is a JMRI tool that keeps all the settings on your computer, so if you ever need to reset a decoder you can just copy the settings using the SPROG2 to talk to the locomotive.
3. Also connect up a short detector as you connect every wire to the main bus. This will identify a fault on installation. Alan Gartner (Wiring for DCC) and others strongly recommend this but it is easy to let haste take over and connect a wire incorrectly.
4. If isolating the frog on switches, test the wiring and insulation before installing. I discovered one "properly" wired switch had some metal filings on top of the insulation and gap I had created, and this caused a small short.
DCC is terrific and really makes operation and general running more fun and realistic. But, it can come with issues. Following the basic rules for wiring should produce many years of reliable running.
