speed curve / Auxiliary function outputs
5.2.3 Auxiliary function outputs
LokSound decoders have 4 physical function outputs,
two for directional lighting, two for auxiliary loads.
A further 10 functions may be activated by pressing
a button to trigger various sound effects.
If you do not want to use the physical function
outputs AUX 1 and AUX 2 you may control another
two sound effects (12 in total).
In addition the functions „sound on / off“ and
„acceleration on / off“ are available. The latter turns
off the acceleration- and deceleration rate and is often
used for precise control of the engines particularly
while shunting. In „shunting mode“ the speed is halved.
Assignment of function buttons
The outputs may be assigned to the available function
buttons. Each function button is linked to a CV in
which any number of events may be combined. Figure
14 on page 25 shows the different possible
combinations and also the ex-factory setting.
Please note:
• Some functions are directional.
• Your DCC command station may not have all
necessary function buttons.
• Each of the function outputs must be turned on or
off separately.
The value that has to be entered into each individual
control-CV is calculated as follows:
Switching on function outputs
Each of the function outputs can / must be turned
on, before it can be used.
You may program any of eight available lighting effects
for each output:
• Dimmer: normal, continuous power to load
• Blinking light: the output blinks with an adjustable
frequency
• Inverse blinking light: the output blinks as usual but
in opposite sequence. This permits to activate
alternately blinking lights.
• Strobe
• Double Strobe
• Random, fire box
• Smoke, for controlling the intensity of the smoke
generator
• Zoom
• Mars light
• Gyra light
There is a CV (CV 113 - 120) for each output, in which
the desired mode may be stored. Please note that you
may deactivate each output with „0“ if it is not needed.
CVs 117 – 120 are only available on LokSoundXL.
The lighting outputs are factory pre-set to „on“. In
steam engines this is also true for the AUX 1 output
that is assigned to the headlight button.
Dimming of lamps
With LokSound you may dim the lamps in 15 steps to
adapt the brightness optimally to your model. The
lamps are pulsed, i.e.: they are continuously switched
on and off. The brightness of each output may be
adjusted separately. The desired dimming value (0 to
15) has to be added to the value of the corresponding
control-CV (113 - 120) that defines the function mode.
Blinking frequency and duration of „bright
period“
If a function output has been set to „blinking“ or
„inverse blinking“, the duration of the „bright period“
(defines blinking frequency) and the on / off ratio
have to be taken from CV 112 (see chapter 7.1).
The „bright period“ is adjustable in 33 steps. It is
always a multiple of 65.5 milliseconds. The On / Off
ratio is adjustable in 16 steps from 1/16 to 16/16. A
ratio of 8/16 indicates that the light output remains
„on“ for the same period as it is „off“. The value to be
entered into the control-CV 113 is calculated as
follows:
Duration of „On“ period (value: 0 – 15) * 16 +
On / Off ratio
