Description

An example of a locomotive decoder (LokPilot)
ECoS controller

Electronic Solutions Ulm (known as ESU) is a German manufacturer of accessories for model trains, especially known for their locomotive decoders.

The products include the LokPilot and LokSound series of decoders and recently the Märklin company has teamed up with ESU for the manufacture of the decoders for their new generation of mfx locomotive decoders. ESU is also an OEM supplier of decoders for a number of manufacturers.

ESU was one of the first manufacturers to produce decoders capable of sound - a feature that has become very popular with model railroaders. Their LokSound v3 decoders have the added benefit that end-users can re-program the sound files used by the decoder, using a LokProgrammer.

Some of their decoders such as the LokPilot and LokSound are multiprotocol in that they support the Motorola format as well as Digital Command Control (DCC) and also Märklin style analog AC current. Their LokPilotDCC on the other hand is a pure DCC decoder and will not work in a pure Märklin/Motorola environment. The ECoS DCC system supports NMRA DCC, Marklin/Motorola format and Selectrix modes.

ESU Products

ECoS

ECoS is a combined command station/throttle which features a number of innovations, such as the graphical display with a large colour LCD. This system is mainly focussed on the European market.

mfx

The ESU mfx format was designed by Marklin, but information is hard to come by. They describe it as a bi-phase format.

It looks a lot like DCC with a zero pulse being 100 milliSeconds in duration, and a logical one represented by a 50 mS pulse. Polarity is not an issue.

Multifunction Decoders

Main article: Electronic Solutions Ulm/Statement Regarding Multifunction Decoder failures

ESU is a supplier of both retail and OEM Decoders. Unlike many other decoder suppliers, ESU doesn't supply different versions of OEM and retail decoders. The decoders are identical. For the Australian and North American markets, the Select OEM decoder is used and identical to the retail decoders. The user can replace the sound files (as long as they are Select sound files.)

LokSound decoders are supplied without any software. The manufacturer or retailer can load software for a specific application. They can also set the defaults for that decoder's application.

A notable user of LokSound decoders with custom sound files is Rapido Trains.

Electronic Solutions Ulm FAQs

Q: "Bricked" LokSound Decoder

Bricked refers to an incident occurring during the software update of an electronic device, rendering it unresponsive.

After updating the firmware in a LokSound decoder using the LokProgrammer, the decoder may be unresponsive. It is possible some Configuration Variables have been altered.

  • Before allowing a firmware update, read and save the decoder configuration to your computer.
  • Upon completion of the firmware update write the saved configuration back to the decoder.

There is a possibility when the firmware update was performed some CVs were changed and those have now become the defaults. A reset will not fix that.

Recovering a Bricked Decoder

In some cases the decoder will require return to the manufacturer for reformatting.

  • The following suggestions are not guaranteed to work.

Firmware Reload

Before making plans to return the decoder, attempt to reload/update the decoder's firmware. Several attempts may be required. If successful, the next step would be to reload the sound project.

Firmware Downgrade

Another method would be to attempt to load an older version of the firmware. Sometimes the LokProgrammer will refuse to update the firmware, stating it is the current version.

Downgrading is done using an older version of the LokProgrammer software. If successful it will downgrade the firmware on the decoder. It can then be updated to the current firmware using a newer version of the LokProgrammer software

Decoder Swap

Sometimes the decoder does not acknowledge the LokProgrammer, which is the root of the issue.

Using an identical decoder, let the LokProgrammer initialize using it, then swap the new decoder for the faulty one. This will fool the LokProgrammer, getting around the issue of the decoder not being recognized.

Additional Resources

See the LokProgrammer page for more details and videos regarding its usage.

Q: Adjust Chuff Rate, LokSound5 Multifunction Decoder

It is possible to adjust the LokSound 5's Chuff Rate.

The CVs used are CV 57 and 58. A stopwatch, calculator and flat section of track are necessary.

Q: What is a LokProgrammer

The LokProgrammer is a combination of hardware and software which is used to configure and load project files for ESU LokSound multifunction decoders.

Loading new projects into the decoder, including sound files, requires the LokProgrammer hardware. The software can be used to determine the configuration, and either manually entered into the decoder or exported and loaded into JMRI.

It can also load new firmware into an older decoder, as well as define the decoder's defaults.

The biggest advantage of the LokProgrammer is the speed at which it can read and write data to the decoder.
