feature is available it is worth changing some functions to momentary for extra play
value and thus giving much finer control over things like horn sounding duration and
buffering-up/coupling noises.
Careful consideration has gone into planning the function button assignments in
this highly specified sound project. Whilst the main sounds and actions have been
kept to lower numbered functions, it has been designed to use
all
available buttons
(F0 to F28) as per NMRA standards. Systems with access to all buttons include ZIMO,
NCE PowerCab, Lenz v3.6, Hornby Elite, Gaugemaster Prodigy, later ESU ECoS)
If your DCC command station is lesser specified and is unable to access buttons
above F20, then you will not be able to operate the tail lights or cab interior lighting.
Here are some work-arounds if you require these lamps illuminated. CV436 = 29 will
put the front markers and tail lamps on together (at opposite ends and directionally
controlled). To switch them all on or off use F0. To revert to front markers only, set
CV436 = 21. For cab lighting, make CV159 = 60, CV160 = 60 & CV454 = 29. This will
set the cab lights to come on whenever the marker lights are switched on, and will
change ends when the direction change button is activated. To compensate for the
fact that you do not have full control of the cab lights, they will only illuminate when
the loco is stationary. As soon as the throttle (speed step) is greater than zero, they
will extinguish. If the marker lights are ‘on’ when the locomotive comes to a halt, the
cab lights will illuminate automatically.
Analogue sound operation (running on DC)
It is a shame to start with a warning, but it is vitally important. Out of the box, your
ZIMO sound-fitted model is configured to run on 12V direct current if required.
All DCC decoders are susceptible to damage if exposed to high frequency track
cleaners (e.g. Relco). Operation may also be erratic if PWM or Feedback type
controllers are in use. For the safety of your decoder, ensure that the track is fed only
with a pure DC supply.
The sound will commence or be maintained at around 5V, whilst the motor will
require a little more to start. By subtle use of the controller, you may, therefore, have
sound playing (and lights) without any movement. Increasing voltage will increase
engine power sounds and vice versa. Automatic and random sounds will play, but you
will not be able to initiate any sound that requires the use of a function button. The
decoder is also set to operate on DC using inertia and back-EMF speed regulation.
uncouple (F8) from the stock, press F6 off to simulate the power handle being moved
to off, and then shutdown the engine (F1 off). The combined pump F13 should be
allowed to run for a short while whilst the hand brake is applied F14. Then its home
for tea, with the cab door F11 being opened and closed.
Scenario 4: Pulling away from a signal check (on a basic 28 speed step setting).
You are on a train, held at a caution signal. The signal clears and you need to apply
power to get the train moving again. Not knowing what the next aspect will be, you want
just to overcome the rolling resistance of the train and ease back on power ready to make
your next driving decision.
This action demonstrates the ease and simplicity of using our sound project, reflecting
the fact that it is not essential to employ 128 Speed Steps (although recommended)
and you don’t have to get into intricacies if you don’t want to. With your train stopped
at the signal, simply and quickly apply 7 Speed Steps on the throttle, as soon as the
signal changes, and leave the speed there. The loco will power up, the train will begin
to move, and once rolling along steadily, the engine power will automatically spool
down. All this is accomplished ‘automatically’ with just one input to the handset.
We love these features, especially in combination, and we’re confident that you will
enjoy the realism they can provide. Of course, you can learn a lot by experimentation,
and develop your own techniques. If you find a new way to utilise the buttons, we
would very much like to hear about it.
Some useful suggestions
User choice and variety is why we made the sounds so versatile in the first place so
we don’t want to dictate how you use your model. However, because this project is
such a radical departure from anything previously offered, a few suggestions and
recommendations are offered here.
We strongly suggest that you only consider changing CV1 & CV29 until you
become familiar with all the nuances and features of your new model. More
importantly, do not assume that any given CV will have the same effect as with other
decoder brands – many are ZIMO specific.
The model is delivered with its locomotive identity/decoder address (CV1) set to 3.
Typically, your DCC controller will allow you to change this to something more
suited (For example, the last three or four digits of the running number).
CV29 is set to 6 to allow for both digital and analogue operation. If you will not be
using conventional control at all, we recommend changing the value of CV29 to 2.
This can enhance integrity of the DCC signal and avoid possible ‘runaway trains’.
DCC systems and handsets vary in specification, some allowing function buttons
to be allocated as ‘momentary’ actions as an alternative to ‘latching’ switches. If this
