Question: Can my TCS DCC decoder run on DC power?

Yes! All TCS decoders are capable of operating on DC track power. This configuration is enabled by default on all non-sound TCS decoders. CV 29 can be modified to enable or disable DC operation on any TCS decoder.

Question: Why is my WOWSound decoder not operating sound functions on DC?

With the exception of OEM decoders/projects such as the Bachmann ACS-64 and Streamlined K4, version 4 and older WOWSound decoders do not feature DC sound operation.

Question: Can I program lighting effects on DC?

While it is not possible to perform CV programming or Audio Assist programming on DC, any configurations set on DCC will carry over to DC. For example, if your engine has been programmed to operate a Mars light, firebox flicker, or directional lighting, those settings will carry over into DC operation and behave as if on DCC.

Question: My DC motor/lighting is reversed but it works fine on DCC. Why?

On DCC, the track power is AC with encoded data and as such is not polarized. Due to this, the engine and decoder are only aware of what direction they are/should be going based on the information sent by the command station. Therefore, "forward" is merely a perspective. Conversely, on DC the track power is polarized. TCS decoders detect the (+) track power rail and base the direction of the motor and lighting depending on which rail is positive. If the track power leads (Red and Black) or motor leads (Orange and Grey) are connected backwards of their intended polarity, the decoder's interpretation/assumption of polarity will be backwards of reality and should be fixed. Make 100% sure your wires are connected properly if you plan to run on DC frequently or exclusively.
