Some DCC decoders
can only operate on DCC layouts. Most DCC decoders will operate on
DCC or Analog layouts. However, Power-Source Conversion (CV12) allows
for operation on other types of layouts as well. |

There are five different conversions available (unless more have been added since this was written) as shown at right: Most of these options exist because the manufacturer of those systems wanted a way to provide decoders that would work on a DCC system as well as their proprietary system. If CV12 is implemented for any of the above conversions, it is activated when you program CV1 (the short address) to zero. To get a decoder that will convert between DCC and one of these proprietary systems, you'll have to purchase that company's decoder. |

Even though Analog is included in this CV12 provision, it doesn't mean that this provision has to be used to have analog operation on a DCC decoder. Many decoders have Automatic Analog Conversion. With this activated in CV29, one only has to take the loco from one layout to the other. CV1 doesn't have to be reprogrammed, nor anything else, providing the default CV29 setup has not been changed to exclude analog operation. Two more obscure conversions exist with Digitrax's Chief and Digitrax's now-discontinued DH140U decoders. Digitrax's Chief allows for Märklin Motorola Trinary decoders to run along with DCC decoders. The Digitrax DH140U also allowed for automatic conversion to run on a DCC layout or Märklin Motorola Trinary layout. All of this illustrates that when you have processor-controlled decoders, there's not much limit to what can be done. There only has to be a need and some decoder manufacturer will fill it. |

| Equipment Requirements for Power-Source Conversion |

If you have a need to run on any of the above proprietary systems, you must be sure to get a decoder that's capable of doing so. Most companies make decoders that will run on DC Analog without implementing CV12. Also, most companies don't make decoders to implement any of the other systems listed above. Typically, if you want a decoder that will do DCC and Trix, for example, you'll have to buy a Trix decoder. None of the decoders carried by Loy's Toys have CV12 implemented. Digitrax, Train Control Systems, NCE, and Lenz decoders will all convert to DC Analog automatically unless programmed not to do so. Throttle Up! SoundTraxx decoders do not have Power-Source Conversion implemented nor do they convert to DC Analog. Power-Source Conversion is
not intrusive. You do not need to bother with it unless you want to
use it. |
