In this video, I go over in detail how I program a Digitrax DH123 DCC decoder, using a DT602 throttle on a Digitrax system.

I will program the 4 digit address on the programming track, which is wired to the programming track outputs on our DCS100 command station.

Once finished with that, I move the engine over to the main line and show you how to adjust the start and max voltage, and add momentum.

Towards the end I briefly discuss the Quick Decoder Setup utility built into the 602 throttle which might make it easier to program 4 digit addresses and make changes to CV29.
