New! Gold Series

Locomotive Decoders

Lenz GmbH is pleased to announce the next generation of model railroad control with the world's finest performing  NMRA DCC decoder with 6th generation Load Compensation (or "BACK EMF") , Silent Drive for exceptional quiet performance and with three new DCC technologies from Lenz:

1) Asymmetric DCC for location specific commands using our soon to be released BM Series for Block management

2) USP Technology*: Uninterruptible Signal Processing

3)  RailCom * : Full bi-directional Communication

4) Gold Maxi is new this summer and is now shipping

 

         

Asymmetric DCC:

Location Specific Commands

When operating a model railroad it is often desired to have some trains under operator control and others running in the background. 

Asymmetrical DCC allows your layout to come alive even if you only have one operator.  You can also use asymmetrical DCC to enforce speed control through important sections of your layout or to stop a train in a siding, in the station, or before an occupied rail crossing. In order to achieve the operation you want with Asymmetric DCC, check out the different levels of block management units. (BM-1, BM-2, and BM-3).

 

USP

 (Uninterruptible Signal Processing) ensures continuous data transfer to the decoder even when the electrical contact with the track is interrupted.

An optional USP storage module can be fitted into the locomotive. The decoder and the locomotive are supplied with power from this storage unit when there is a interrupted power supply on the track (e.g. a dead frog or dirty track).

DCC instructions continue to be received by the locomotive even when on dirty track.

 

Full Bi-Directional Capabilities

RailCom introduces a whole new generation of capabilities for DCC by providing for the first time the ability of a DCC decoder to communicate performance information back to the command station.

  • Fast locomotive identification 

  • Decoder initiated information

  • Track train location

  • Fast read back of CV values while programming on the main

  • DCC command acknowledgement

 

Features include:  (please note there is a different of functions, and amperage, see chart below)

 

 Motor control
The decoder has a high-frequency control (23kHz). To adapt it to the type of locomotive used, you can simply choose between different motor types. These individual motor types include parameter sets which have been specially adapted to the respective models. Moreover, it is also possible to carry out fine-tuning via various CVs.

The minimum, maximum and mid speed can be set; the decoder adapts the characteristic speed line dynamically to ensure a steady, even curve. It is also possible to program an individual characteristic speed curve.

Overload protection
The decoders are protected against overloading, short circuits and overheating.

Starting and braking delay
The starting and braking delays can be set independently of each other. These delays can be enabled and disabled via a function by pressing the key of the digital system once.

Constant braking distance
A special feature of the GOLD decoder provides for a constant braking distance independent of the current speed of the locomotive. This feature is important for model railway operators who install automatic stopping sections in their layouts.

Switching speed
The shunting speed can be set via a function; it halves the speed.

 ABC = simple signal stop and slow approach using Asymmetrical DCC

You can carry out a particularly simple signal stop using the ABC braking module. Combined with the constant braking distance, precise on-the-spot stopping in front of red signals is not a problem.

The signal indication "Slow approach/Caution" does not pose a problem; the respective speed can be set via a CV in the decoder.

You can operate all functions during the signal stop or slow approach - you can even reverse away again from the red signal.

Push-pull train control
A push-pull train control can be set if the ABC braking module BM2 is used. There are two different options: push-pull operation with and without intermediate stops. The latter also takes slow-approach sections into account. The stopping time at the end of the track and at the intermediate stops is set at between 1 and 255 seconds via a CV.

USP*
In combination with the optional energy storage, the intelligent USP circuit ensures that your locomotive can run even over dirty track sections or dead frogs. The energy storage is installed separately in the vehicle.

RailCom*
The GOLD decoder is equipped with the RailCom function. In addition to the locomotive address, other data (e.g. speed, CV content) can be transmitted from the locomotive via the track back to the system and displayed.

Function outputs
Four function outputs can be mapped to the functions of the digital system according to NMRA specifications.

Lighting effects
Different lighting effects can be set at the four function outputs:

The S.U.S.I. interface
The S.U.S.I. interface enables the connection of sound or function modules which support this interface.
