Older  4 Digit Numbering Methodologys

Digital plus by Lenz NMRA DCC locomotive decoders are designed to fully conform to all NMRA DCC Standards and Recommended Practices. This ensures care free interchange of our locomotive decoders with all other NMRA DCC systems. No excuses, no words designed to confuse, just 100% pure NMRA DCC backed up with NMRA conformance and inspection warrants and the industry's best warranty.

All newly released decoders have passed passed all the automated NMRA DCC tests.

We differentiate our locomotive decoders according to the maximum continuous draw of the motor output. While the stall current is an important number if the locomotive motor can actually stall, we have found that most modern locomotives do not stall.  Instead what is important is how much load the motor will place on the decoder during its maximum load. 

New decoder code expansion now shipping!

For future updates all Gold,  Gold+, SILVER+, STANDARD+  decoders can have their software upgraded using the Digital Plus decoder programmer even after the decoder is installed in the locomotive. Future decoder firmware updating is dependent upon the decoder's hardware capability.

*        With our new + Series  each function output supports F0-F28 with simplified function mapping
*        All new + series  decoders also offers   full RailCom NMRA DCC Bi-directional support

To determine the maximum continuous draw of a locomotive, run the locomotive at 16volts DC and hold back the locomotive as you would if you were cleaning the wheels.  The current draw measured is the maximum continuous current draw.  In general HO locomotives draw less than 1 amp continuous and N scale locomotives draw less the  0.5 amps continuous.

Motor Drive Options

Digital plus by Lenz NMRA DCC decoders all have exceptional motor drive capabilities.  \

• GOLD +, SILVER+, and STANDARD+  (Silver + and Standard + are now shipping, Gold + - due out  spring 2010)
•    Gold Series and Silver Series,

The new Gold Series give the ultimate control with three new technologies from Lenz. These three new technologies offer greater precision control with Uninterruptible Signal Processing (USP), Data transmission (RailCom) and automation (Asymmetric  DCC.) A full description of these technologies can be found on the we site under GOLD Series  Decoder and Technical Information.  The Silver Series has the same motor drive as the GOLD decoder and supports Asymmetrical DCC.

• Ultra-Drive (LE1835 and Older STANDARD decoder)

The LE1835 is a high precision silent back emf decoder with 4 function outputs, independent or directional lighting effects that can be dimmed using a function, advanced consist control, extended addressing, operations mode programming and outstanding 128 step motor control.  The combination of Back EMF and Silent Drive allows for a flawlessly smooth, quiet performance.

• XS Silent Drive™ Decoders (older LE080's)

Silent Drive is a  revolutionary motor control circuit that allows the decoder to operate motors extremely quietly and smoothly. No longer will your motor make noise when you operate on DCC.  To achieve this result you need a motor drive that can operate the motor in excess of  20Khz.  Decoders that operate in excess of 20kHz are also recommended by manufacturers of coreless motors. Our XS decoders operate in excess of 22kHz.

·         Drive-Select™ Decoders (older 1014's)

Drive-Select decoders provide user configuration for either Silent Drive for the ultimate quiet drive or Precision Glide Control for smooth low speed operation.  This lets the user select the motor drive type that is best for both the locomotive and user preference.

• Precision Back EMF Load Compensation Motor Control

Back emf is a decoder feature that allows the decoder to adjust the voltage to the motor based on the motor’s load. This provides true prototypical operation at slow speeds and provides the illusion of operating heavy trains. For Ironless Core motors or for installations where exceptionally smooth slow speed operation is desired, we recommend our line of back emf decoders. We are into our fifth generation of back emf control and now pro\vide 12 bit resolution with exceptionally smooth performance.

Plug Type Options

NMRA DCC decoders can come with a variety of plug types.  A plug is a device that allows the decoder to be plugged into the locomotive without wiring.  Most modern HO locomotives and a growing number of locomotives in other scales have come equipped with sockets especially designed for NMRA DCC Decoders.  We currently support three different plug types.

NMRA Small plug -  a 6 pin in line plug used in a growing number of N scale locomotives. These connectors are common in Trix and Roco N Scale locomotives.

NMRA Medium plug -  the common 2 pin by 4 pin socket found in many HO and larger scale locomotives

NMRA JST 9 pin socket - used primarily as a connector between the decoder and the locomotive, this connector is also used in locomotives that have wire harnesses instead of circuit boards.  The Athearn 2-8-2 is an example of a locomotive that uses this connector.  Decoders with JST plugs can also be used with a variety of harnesses produced by other manufacturers.  JST equipped decoders are shipped with a variety of harnesses. The harness type is indicated by the following -HT designations

-JST - no harness included
-WH - a 200 mm JST wire harness is included
-MP - a 88mm long JST harness is included with NMRA 8 pin medium plug

Our older Model Number Identification For Our 4 digit model number decoders

LE 1234H
The LE prefix is our product designation for locomotive decoders.
Next is a 2 digit number (12) that indicates the maximum continuous current rating for the decoder.  For example, 05 means .5 Amps, 10 means 1 Amp and 40 represents 4 amps.

Following the power rating is a single digit (3) that indicates the decoder drive type.

The first of these numbers is the drive type

Following the drive type is a single digit (4) that  indicates the number of functions and construction type

Following the 4 digits is a single letter which represents the type of harness the decoder is equipped with.
