Digitrax Products/Digitrax Throttles

The R suffix indicates the throttle is radio equipped. R Throttles are also simplex mode, operating in the same way as an IR throttle. Radio communications require the UR91 panel.
The D suffix indicates a Duplex mode radio throttle. They function exactly the same way as a wired throttle. The first time they are used during an operating session they must be plugged into a utility panel, so the system can identify and configure the throttle. Once that process is completed, the throttle can by used wirelessly for any operation, including programming. Duplex throttles require the UR92 panel to operate wirelessly.
=== DT602 Advanced Super Throttle ===
This throttle has a number of new features. First is a completely new, more ergonomic case. While very similar to the DT500 series, it has been completely redesigned, with a larger colour LCD and much fewer pushbuttons. For wireless operations it uses three AAA cells instead of a 9V battery, and features an On/Off button. The throttle has power saving modes, and will accept rechargeable AAAs as well. While it does have a cord for connection to the layout, it unplugs from the throttle. 
==== DT602D Advanced Duplex Super Throttle ====
The DT602D features Duplex Scanning to find available networks and signal strengths. It does not need to be tethered to do join a throttle network wirelessly. 
==== DT602DE ====
European wireless model with CE certification.
==== Videos ====
:Also see the video review of the DT602D.
=== UT6 ===
The UT6 Family appeared in late 2020. The UT6 is the tethered version with a UT6D and UT6DE being wireless duplex throttles.
The UT6 features:
* Colour 1.5” LCD Display
* Numeric keys
* Forward/Reverse toggle switch with braking
* On/Off Switch, uses AA cells or BP600MH battery
* 29 Functions
* Infrared operation with UR90/91/92 (All models) 
* Locomotive Recall 
* Detachable LocoNet cable and Lanyard
The UT6 replaces the UT4 series of throttles.
=== DCS52 All-in-one Command Station/Booster/Throttle ===
Otherwise known as the Zephyr Express, Zephyr Xtra (DCS51) and Zephyr (DCS50).
=== WTL12 All-in-one Command Station/Booster/Throttle/Sound System for Walthers' Trainline RailTech Train Set ===
Simple DCC system sold by Walthers. Similar to the Zephyr in concept. Fully expandable with Digitrax products.

Digitrax Products/Radio Panels

== Radio Panels ==
===UR91 Radio Equipped/IR Receiver Unit===
The UR91 (Discontinued) adds simplex radio operation. Operates in the 900 MHz band, can support up to 10 radio/IR throttles. Supports simplex radio and IR simultaneously.
Usually only one is needed for radio operation. Simplex throttles must be connected to the panel by their cable to program, select or dispatching a locomotive. 
===UR92 Duplex Radio Transceiver/IR Receiver===
The UR92/UR92CE (retired in February 2021) is a duplex radio so that throttles do not need to be tethered to select or dispatch a locomotive. Supports up to 20 duplex throttles. Most installations will only require one UR92. Also supports the IR throttles.
Duplex radio operates in the 2.4 GHz band, simplex is not supported. Includes Group Mode, to minimize interference at shows when several Digitrax Duplex systems are in use. 
====UR92CE Duplex Radio Transceiver/IR Receiver for Europe====
Version for the EU.
=== UR93 Radio Panel ===

=== Notes ===
# LocoNet ID: See LocoNet page for details about the LocoNet ID. The UR9x series use this feature.
# The DT602 supports IR operation, the location of the IR emitters on the throttle's body result in erratic operation. 
==== UR90 ====
This is the Infrared Equipped Panel that can work with any throttle. Several will be needed as they are line of sight units.
Supports up to 10 throttles.
==== UR91 ====
Simplex Radio, 900MHz. Most layouts require only one UR91. IR is also supported.
===== Simplex Notes =====
Throttle must be physically connected to select, dispatch or program a locomotive. 
==== UR92 ====
Duplex Radio in the 2.4GHz band. Range is approximately 900 feet. IR operation is also supported. UR92CE is the same unit built to European Standards

Distributed Power

Distributed Power is another form of Multiple Unit Consisting, which has origins in the 1960s.
Instead of all the motive power being located on the front of the train, locomotives will be located in the middle of the train as well. They are controlled from the head end via radio control. Older consists used a robot to control the mid train locomotives. Robots were usually converted B unit locomotives, whose prime mover had been replaced by radio equipment. A common radio control system was Locotrol
The greatest benefit of distributed power—and the reason for development of the original concept—is the reduction of draw-gear draft forces, permitting a wholesale increase in the size of trains without exceeding draw-gear strength, through the use of mid- or end-of-train locomotives.
This can be modelled using Digital Command Control's ability to consist locomotives.
Ditch Lights

Ditch Lights are small headlights mounted on the pilot, designed to illuminate the portion of the right of way not normally illuminated by the headlight beam. 
First appearing in Canada, where it was noticed that when the ditch lights were on while approaching a road crossing the ROW, motorists assumed the train was much closer and didn't attempt to beat the train when crossing the track. After investigating their effectiveness in reducing collisions with automobiles, regulations were drafted requiring the ditch lights be illuminated whenever the train approaches a level crossing.
In time this practice was adopted in the United States.

Doehler and Haass

Doehler & Haass Control Systems GmbH & Co. KG is a European manufacturer of command control components.
They make a number of decoders that work with Selectrix SX1 and SX2, as well as NMRA DCC. Many of their products also support Asymmetric DCC. 
D&H developed the Selectrix command control system, and are the sole supplier of the ICs required. They shopped Selectrix to various manufacturers in Europe beginning in 1980, with no interest. In 1987 Trix began selling and supporting SelecTRIX under an exclusive marketing agreement. 
See their website for more information. 
Note: Website is in German.
==Company Description==
From their website:
(Translated from the original German text.)
Since 1975, Doehler & Haass (D&H) has been developing, producing and selling components for the digital control of model railway layouts.
As early as 1982, TRIX was the first series manufacturer to present the "SelecTRIX" system developed by Doehler & Haass. This was a fully functional digital system that already had a load control system that enabled authentic driving operation for the first time. It took many years before competitors were able to offer this decoder technology.
During this time, Doehler & Haass developed a special, customer-specific circuit (ASIC). As early as 1984, it was possible to produce what was then the world's smallest locomotive decoder. Since then, this ASIC technology has been consistently further developed and ensures, among other things, the excellent motor control (Super Soft Drive / SSD)®, which is widely praised by customers.
Doehler & Haass products support all common model railway standards, such as SX1, SX2, DCC, MM, ABC and RailCom. Not only are they represented on the market under the name Doehler & Haass, but well-known manufacturers also incorporate them into their own components (OEM business). The product development is continuously continued and thus offers customers a constantly expanding product range that meets all wishes.
As a special service, Doehler & Haass provides free software updates over several years, as well as the free download of sound projects from the studios of renowned sound designers.
Almost all system components offered are manufactured in Germany. Particular attention is paid to the use of high-quality materials and careful workmanship, which ensures a particularly high level of reliability. And all this at a very attractive price!
Dynamic CV

These Configuration Variables are subject to change.
== Dynamic Configuration Variables 880-895 == 
CVs 880-891 are currently reserved by the NMRA for future usage. Currently there seems to be little usage of these CVs. CVs in this range are dynamic and are used for Unsolicited Decoder Initiated Transmission. 
=== Decoder Load, CV 892 ===
This specifies the current load on the decoder as a 7-bit number. Bits 0-6 indicate the load, zero being no load. Bit 7 indicates a positive or negative load.
This CV is volatile and is lost during a power interruption.
=== Flags, CV 893 ===
Up to 8 dynamic flags can be transmitted. Bits 0 to 7 are reserved for future use.
=== Fuel/Coal, CV 894 ===
A value stored here indicates the level of fuel, such as oil or coal, onboard. The locomotive will stop when it reaches zero. A value of 254 means a full load of fuel. If the value is 255, it means this feature is not supported and the contents of the CV are not to be transmitted.
=== Water, CV 895 ===
Same idea as the Fuel variable, it indicates the amount of water onboard. When the water is consumed (0), the locomotive should stop, as it would in real life. Many accidents occurred when the water level in the boiler decreased to a dangerous level, usually resulting in the failure of the crown sheet and an explosion.
== SUSI ==
Configuration Variables 896-1024 SUSI (Serial User Standard Interface).
:Note from the NMRA
:;Reserved until March 2005 for use by SUSI to define CVs for Sound and Function auxiliary modules. See Technical Note TI-9.2.3 for details.

E-Stop

E-STOP or Emergency Stop is a special speed step defined in the NMRA Digital Command Control Specifications.
For more information see the page on DCC Packets.
 
==E-Stop Command==
Speed Steps 	Speed Steps
C S3 S2 S1 S0	Speed
00000 	Stop
10000 	Stop*
00001 	E-Stop
10001 	E-Stop*
Inside the DCC Packet is a set of bits reserved for speed step information. If all of the bits are set to a value of zero (0000 for 28 and 14 speed steps) the addressed decoder moves to the stop position.
If the Least Significant Bit (S0) is set to one (0001), the value is the E-Stop command. E-Stop is a Broadcast command, meaning that all decoders will immediately change to STOP and all moving trains halt.
By pressing the Emergency Stop button on your throttle the command station generates a broadcast packet with the E-Stop command and that is immediately transmitted to the booster and onto the rails. Everything in motion will immediately stop. The Standard states that the decoder shall immediately cease applying power to the motor.
 The E-Stop command does not disconnect power to the rails. A valid DCC signal remains. Any multifunction decoders set to allow Analog operation could be set their locomotive in motion by a corrupted DCC signal, and may not respond to the E-Stop command. 
* These commands are optional, and can be ignored for direction sensitive applications.

== Operational modes ==
The ECoSBoost is connected directly to the ECoSlink jack, from where it gets its control signals. Basically it is capable of amplifying and delivering to the track these data formats: DCC, Motorola, Selectrix® and mfx®.
== Models Replaced ==
This version replaces the 50010 4amp and 50011 8amp models which have been discountinued.
ECoSLink Terminal

The ECoSlink Terminal is connected to the ECoS or central station. It offers on the front panel two jacks for hand controllers and on the back are four sockets for devices mounted under the layout. These include ECoSBoost booster and ECoSDetector feedback modules.
==Features==
The ECoSlink Terminal can provide power to all attached devices either from the ECoS power supply, or from an external power supply through the ECoSlink themselves. 
If more than one ECoSlink Terminal is used, the terminals can be connected to each other with standard Ethernet patch cables. 
=== Flexibility ===
The ECoSlink Terminal can be used on ECoS and central station®. The is passively distributed together with the supply and booster cables and the termination is ensured. 
=== Compatibility===
* ESU ECoS 50000
* ESU ECoS 50200
* Märklin® 
** Central Station 60212 with original Märklin® software 
** Central Station 60212 with ESU firmware 3.0.0 "Reloaded"
** Central Station 60213 "Central Station 2"
ECos 50200

The ECoS 50200 is already the second generation of our successful ECoS command station. With the latest ECoS command station, ESU continues to offer state-of-the-art digital technology combined with contemporary functional range and easy handling all this for a fair price-performance ratio.
As a multi-protocol command station, ECoS supports DCC, Märklin® Motorola®, Selectrix® and the M4 data protocol. M4 drives and controls locomotives equipped with mfx® decoders without any restrictions. M4 is completely compatible. You can even continue to use almost all of your present loco decoders. ECoS is therefore the only digital command station worldwide that unifies 4 data protocols.
ESU/Statement Regarding Multifunction Decoder failures

From a statement published on the ESU forums:
Frying Decoders
06.12.23
Thanks for you explaining your situation and sorry for the late reply. We found that some LokSound 5 decoders we produced at the beginning of 2023 have been used a power supply IC that was not up to our standards, either a fake or "B grade" component. If the component fails, the MCU will not be powered, thus the decoder fails. While extensive testing was done in our lab, we were not able to make the decoders fail. Unfortunately a small portion of these decoders have failed in the field. The failure has nothing to do with the locomotive, the programming process, nor the decoder firmware used. The component may never even fail which we have found is the vast majority. 
ESU continues to stand behind its products and our industry leading 2-year ‘no questions’ asked warranty applies of course. Every customer can send decoders to our ESU LLC office for replacement directly. Please note that OEM decoders must be exchanged under the warranty of the OEM manufacturer. 
The chip crisis has been hard on the industry as a whole but is recovering. We apologize for any inconvenience caused by this issue and want to thank you for your strong support.
Mit freundlichen Grüßen
Ihr ESU Support Team

==Description==
The LokPilot V4.0 DCC is a "thoroughbred" DCC decoder. Except for the Motorola® and Selectrix® protocol, it supports all functions of the LokPilot V4.0. In analogue mode, it can only operate on DC-powered layouts.
The LokPilot V4.0 DCC is best suited for the DCC purist who does not require multi-protocol operation and does not want to pay for it either.
ESU 54615 SW1200RS

Category:ESU
Category:Decoder
 
==Rapido GMD SW1200RS Decoder Matching ==
Rapido goes through each and every sound project and sets it up to best work with what they want for lighting and motor control in that project. 
For this reason there are a quite a few changes from the default settings which is why they recommend getting their decoders preprogrammed. Some functions are only available on ESU decoders, this is the reason for the ESU recommendation. If MU’ing (consisting) with a factory sound equipped loco those features would not be available in a non ESU decoder. When consisting it is always easier to use the same brand in each loco in the consist.
=== Setting Up an ESU 54615 LokPilot V4.0 DCC decoder ===
This is a list of CVs which would need changes in the 54615 to match the sound equipped LokSound Selects in the SW1200RS. This list is long and will be tedious to manually enter, though it is possible…. As you can see from below, this is why a pre-programmed decoder is recommended on the Rapido products.
:If you attempt this, do it in the sequence below as the order of the index CVs (31 and 32) is important. 
If needing a reset: Setting CV8 to a value 8 ON THE PROGRAMMING TRACK, not on the Main, will allow you to start over if a mistake occurs.

=== Acknowledgements ===
Thanks to ESU LLC for all the details.
As the list demonstrates, purchasing a Rapido locomotive with the ESU decoder installed is much easier, or purchase the ESU decoder from Rapido directly if you are retrofitting a locomotive.
==== LokPilot/LokSound v4 Obsolescence ====
The v4 decoders became obsolete in 2019 when parts required to manufacture them were discontinued. The LokSound V5 DCC replaced them.
