Features: Switching Speed, Normal
Direction of Travel & Scalable Speed Stabilization
(Back EMF) Features
Switching speed
is controlled by CV54. The factory setting is 000 for
OFF. To turn on the switching speed feature, program CV54 to a value
of 001. When this feature is on, use F6 to activate and deactivate switch-
ing speed. With the feature on the throttle’s target speed is effectively
reduced by about 50% and the effects of accel and decel programmed
into the decoder are reduced by 1/4. This is useful for yard switching
operations.
Normal Direction of Travel
is controlled by CV29. See your decoder
manual or the Digitrax Toolbox App for additional information on the
settings for CV29.

System
Digitrax SoundFX lets you make your locos sound in scale like the real
thing! The SoundFX sound CVs in the range of CV140 to CV256 let you
customize your decoder without having to reprogram or change the
installed sound scheme. Standard decoder CVs in the range of CV01 to
CV120 operate the same as for a non-SoundF

Digitrax decoders (they
control motor and light functions etc.) CV58 is used as Master Volume,
and CV60 is used to select an alternate scheme, if provided in the sound
project. Sound CV155 is provided to select Diesel engine “notching”
modes. The default of CV155=00 provides “automatic notching” that
changes the diesel RPM settings at 8 distinct throttle speeds that are
controlled by Sound CV132. Sound CV155=01 selects “semi-automatic
notching” mode that allows F6 ON to increase the notch from the current
throttle setting and F7 ON to decrease back towards the lowest current
throttle notch setting. Sound CV155=02 selects “manual notching” mode
that allows F6 ON to increase the notch setting and F7 ON to decrease
the notch setting irrespective of the throttle setting, which controls just
the motor speed. The decoder’s sound scheme can be reloaded using a
Digitrax PR3 programmers and a sound project file from the Digitrax
Sound Depot on our web site. Typical sound downloads take between 50
and 100 seconds depending on the project complexity and file size. The
following tables show the CVs used in this decoder version and how it is
set up at the factory to operate various sounds using your throttle
