N Scale H15/16-44 DCC Decoder

The N-scale H15/16-44 DCC decoder can be used with all popular NMRA-compliant DCC systems. This decoder is in full conformance with all NMRA Standards and Recommended Practices and has been augmented to work well with all major DCC systems on the market.

The N scale H15/16-44 decoder is packed with all the features that you expect in a high-end decoder:

Special lighting effects for front and rear headlights including directional, independent, dimming, Mars light, Gyro light, single Strobe, and double Strobe.

Directional bi-color (green and red) front and rear marker lights.

Supports both short (2-digit) and long (4-digit) addressing.

Advanced consist control (operating and controlling several locomotives as if they were a single entity by sending speed and direction commands to a common consist address that is stored in the decoder of every locomotive in the consist).

Operations mode programming (programming on the main line).

Full support for all the various motor speed-step modes, including the 128 speed-step mode.

Choice of either Precision Glide Control or Silent Drive for motor control.

Many characteristics of the H15/16-44 decoder can be programmed to customize the decoder to its locomotive. Please read The Configuration Variables and their Definitions section for details on the configuration variables supported by the H15/16-44 decoder. The H15/16-44 decoder supports all forms of programming described in NMRA Recommended Practice 9.2.3, including the user friendly direct CV (Configuration Variable) programming mode and operations mode programming. For example, you can operate the decoder with the factory-default speed curve, or you may specify your own customized speed curve. You can also set which end of the locomotive is to be the forward end. You can even decide whether or not you want to be able to operate the locomotive on conventional DC layouts. If your DCC system supports operations mode programming, you can change the values of all CVs

(except for the locomotive’s 2-digit, 4-digit, and consist addresses in CV1, (CV17 and CV18), and CV19; respectively) while the locomotive is on the main line.
