The default address for DCC operation is “03”.
The default address assigned to the LokSound decoder is 3. Simply set your
controller to this locomotive number and place it on the mainline. If everything is
set up properly, the “Princess Royal Class” should react as shown on the table 3.1.
If you use a DCC system which supports RailComPlus
®
, it will most likely ask
you to change the locomotive address. All function button icons will be displayed
correctly after the assignment of the new address.
The default address assigned to the LokSound decoder is 3. Simply set your
controller to this locomotive number and place it on the mainline. If everything
is set up properly, the “Princess Royal Class” should react as shown on the
table 3.1. Usually, under Motorola
®
system, you can control the function buttons
F0, F1 to F4 only. However, you can enable a LokSound special feature. Besides
the normal locomotive address the decoder then “listens” also for the next
address. If you use this address with your 6021, you can activate the functions F5 to
F8 by pressing F1 to F4. To enable the second Motorola
®
address, you may change
CV49, Bit 3 (see programming table).

Each LokSound decoder requires a definite address to be addressable for the
central unit. Depending on the type of decoder and the digital system, there are
several possibilities how to allocate addresses. The LokSound may be setup to
listen to either the primary address (also called “short” address), which provides
a range of 1 to 127 or the extended (“long”) address, which has a range of up to
9999. Based on your preferences and your command station’s capabilities, you may
select either the primary address or the extended address for usage. Be aware that
some DCC systems do not support the full range of available addresses. Bit 5 in
CV 29 switches between short and long address. The decoder can only respond to
one address at a time.
If CV 29, Bit 5 is cleared, the decoder listens to the primary address stored in CV 1.
If CV 29, Bit 5 is set, the decoder listens to the extended address stored in CV
17 AND CV 18.
Normally you would control LokSound decoders with the short address that is
stored in CV 1. In DCC mode, the permitted values range from 1 to 127. In order
to enable the decoder to “listen” to the short address you must delete bit 5 in
CV 29.
Some digital systems (e.g.: ROCO
®
Lokmaus2, Lenz
®
digital plus, Lenz compact)
only support the values 1 - 99 as short addresses.
You can also operate LokSound decoders with extended addresses (4-digit
addresses). The supported values range from 128 - 10239. The extended address
is stored in CVs 17 and 18. You must activate the usage of the extended address
by setting bit 5 in CV 29.
If you want to use your LokSound with the extended address it is practical to
programme this address directly with your digital system: most modern digital
systems have a menu for programming long addresses. The command station
not only programmes CV 29 correctly but also assures the correct storage of
the values for the long address in CV 17 and 18.
Both the primary and the extended address may be changed at any time using
service mode (on the programming track).
Some DCC systems (such as ESU ECoS, ESU Navigator) will allow the decoder
address to be modified using Programming On The Main. LokSound will accept
the programming commands, but the following restrictions apply:
l
If the decoders primary address is enabled, the decoder will accept a new
primary address and follow this immediately.
l
If the decoders primary address is enabled, the decoder will accept a new
secondary address (write of CV 17, 18)
l
If the decoders extended address is enabled, the decoder will only accept a
new primary address. You can not change an extended address to another
number using Programming On The Main.
You can also operate LokSound decoders with the Motorola
®
format. The address
for this operating mode is stored in CV 1.
This address is identical to the short address in DCC mode. The LokSound
decoder responds both to commands in DCC and in Motorola
®
mode at the
same time.
Märklin
®
digital devices (6020, 6021, Delta
®
) can only work with addresses
from 1 to 80. Should you have entered a higher value in CV 1 you will not be
able to drive this locomotive with these central units.
3. Decoder settings
Have a look at the explanations for CV 29 in the table on page 10: firstly, decide
which options should be active. The column “Value” has two numbers for each
option. If the option is switched off, the value is 0. Otherwise, it is a number
between 1 and 128. Add all the values for the respective options to arrive at the
correct value for this CV.
LokSound decoders support all NMRA programming modes as there are the
programming track modes (Direct Mode, Register Mode, Paged Mode) and the
mode for the main (“POM”, “Programming on the Main”).
Programming on the Main (also called “Operations Mode programming”) enables
you to programme your decoders comfortably without having to remove
the locomotive from the layout. In this case, the command station talks directly
to the decoder by using its locomotive address, for instance:
“Locomotive number 50, write the value 7 into CV 3!”. Thus knowing the
locomotive address is a precondition.
This programming mode usually requires the locomotive to be placed on a special
programming track output of the command station. CV’s can only be read on the
service track unless your DCC command stations supports RailCom. You can
also reprogramme the locomotive address without knowing the old address
since the command station simply transmits the command “Write value 7 in
CV 3!”
In order to be able to read back the CV values from your decoder, the motor
terminals must be properly connected to the motor. The motor is used to produce
the “feedback” current detected by the command station.
As each DCC system is different, the procedure for changing a CV will vary
depending upon the system. We are very sorry that we are unable to provide
detailed instructions to cover every system on the market. We need to assume
that you are familiar with your system. Please consult your DCC system manual
for detailed specification. We tested the LokSound with almost every DCC
system available on the market (as of end of 2010), so there should not be any
general problem.
The LokProgrammer 53450 / 53452 offers the easiest and most comfortable
way of setting the CVs of the LokSound decoders: simply by a few mouse clicks
on an MS-Windows
®
computer. The computer helps you look for the various
CV numbers and values. More information is contained in the manual for the
LokProgrammer.
You can access all properties of ESU decoders with the LokProgrammer. You
even can erase the sound and download a new soundpackage. Please see our
website for more details.
Although we highly recommend the use of a DCC system in order to enjoy all
features of the LokSound, you may also use your conventional DC or AC
controller. You will be able to control the motor of the locomotive and will also
hear the engine sounds. However, you can not control any additional sound
effects such as horn because of the lack of any function buttons.
The table starting on page 10 covers setting of the most important parameters
of the LokSound decoder. A full list of CVs can be found in the reference manual
available for download under
www.esu.eu
The hardware determines some features such as the number of function outputs as
well as the maximum permitted current of the motor output and therefore they
are not programmable. Nevertheless, there are plenty of possibilities to influence
the behaviour of the LokSound decoder by adjusting software-governed properties.
There is at least one memory space within the decoder reserved for each
adjustable parameter where numbers or letters can be stored.
You could visualise the storage spaces as index cards in a large file box. In order
to enable you to find the right card again, they all have numbers and / or names
outlining the properties of this particular card such as “locomotive address” or
“maximum speed.” Then imagine that you can write information onto these cards.
Adjusting the settings means nothing else but erasing one entry and replacing it
with another. Moreover, you could do that at any time. However, you cannot
write onto every card: some bits of information like the manufacturer’s code
are firmly encoded.
Thus, you can determine the content of the storage spaces in the decoder even
during operation and of course, the decoder will follow the instructions. Via the
procedure known as “Programming”, you can enter the desired data into the
storage spaces.
The LokSound decoders follow the CV concept developed in the US. CV stands
for “Configuration Variable” and indicates that the storage cells described above
are not only variable but they also determine the behaviour of the decoder.
The NMRA (National Model Railroad Association) has defined which CVs
determine certain parameters of a decoder. The DCC standard allocates fixed
numbers for certain CVs (adherence is obligatory). This greatly simplifies things
for the user since decoders of most manufacturers comply with this standard
and therefore dealing with CVs requires the same process with the same CV-
numbers regardless of the manufacturer.
The DCC concept permits you to enter numbers ranging from 0 to 255 into
CVs. Each CV carries only one number.
While the position number is predetermined, the range of values may vary. Not
all CVs must accept values ranging from 0 to 255. The permitted values for
LokSound decoders are listed in the table staring on page 10. showing the most
important available CVs.
Most CVs contain numbers: CV 1 for instance contains the locomotive address.
This can be any number between 1 and 127. While most CVs expect numbers
to be entered, some others are rather like a “collection point” of various “switches”,
that administer different functions in one CV (mainly “on” or “off”): CVs 29 and
49 are good examples: you must calculate the value for these CVs yourself.
The value depends on which settings you want to programme:
