Premier EF-3 Electric Engine w/Proto-Sound 3.0
Programming Track (for DCC operation)
Your MTH Proto-Sound 3.0-equipped locomotive does not program well on
Programming tracks due to the inclusion of super capacitors utilized in the locomotive's
electronic package. The super capacitors provide backup power to the electronics,
allowing the locomotive to better negotiate track sections suffering from poor electrical
conductivity. This ensures that sounds continue to play, the locomotive continues to
move forward and lighting remains lit. During power shutdowns, the super capacitors
provide power to allow the locomotive shutdown sounds to continue playing through
their conclusion. Unfortunately, the super capacitors require that operators ONLY
program engine CV’s using Programming on the Main (PoM).
Loading Engine Firmware
Your new MTH PS3.0-equipped O-Gauge engine affords you the ability to load Engine
firmware. Loader version 2.30 or later will allow you to do this. Please refer to the
Loader program’s instructions for more details. So, as MTH releases new features or
updates you will be able to take full advantage without having to ship your favorite
engine anywhere. All new updates are available on our website. MTH will make
announcements as they are available. Not all updates will apply to all engines.
NOTE: Requires a TIU w/version 4.20 or later firmware, and requires Consumer
Loader version 2.30 or later.
