The function numbers entered here must be set up, using function mapping, so they do not
switch other outputs on. It must also be ensured that the outputs used for the red lights can
not be controlled by other function keys, due to function mapping, i.e. the function mapping of
function keys set up here must be set to zero. So that the lights are switched off correctly,
both CVs 107 and 108 must always be programmed accordingly. If one of CVs 107 or 108 is
programmed with a value of 0, the function is deactivated.
The value for programming CVs 107 and 108 is determined by two factors. Firstly, on which
of the outputs A1 o A2 the light is to be switched off, and secondly, with which function key f1
to f12 is the light to be switched. Since a CV can only be programmed with a single value,
these factors are combined into the value according to the following schema:
Light Assinment: A0f = white light front, A0r = white light rear
CV107 for red light front
CV108 for red light rear
Calculation: Output * 16 + Function key
Example
: The front red light is to be connected to A1 and switched with f5.
CV 107 = 1 * 16 + 5 = 21
The rear red light is to be connected to A2 and switched with f6.
CV 108 = 2 * 16 + 6 = 38
Märklin braking section
The decoder reacts to a Märklin brake section (brakes with analog power on the track), if
CV29 bit 2 and CV49 bit 7 are set to 1 (factory setting 1 and 0).
Programming the Sound decoder
In factory default state, all decoder options are changed using configuration variables (CV’s)
according to the DCC standard. The decoders can be programmed by an Intellibox, DCC
Centre and Motorola Centre
.
Programming with the Intellibox
Irrespective of the format to be driven later, we recommend that the decoder be programmed
via the programming menu for DCC decoders.
The Intellibox supports DCC programming with a simple input menu. Long addresses do not
have to be laboriously calculated, they can be entered directly. The Intellibox automatically
calculates the values for CV17 and CV18.
For the exact process please read the appropriate chapter in the Intellibox manual
.
Special case locomotive addresses 80 to 255 in Motorola format
In Motorola format the Intellibox supports an address range of 255. Addresses 1 to 80 can
also be programmed easily using DCC programming mode. If an address above 80 is to be
programmed however, it must be done as described in the chapter “Programming with a
Märklin Centre”.
With this programming technique CV 1 will be set to 0 and the decoder will use the Motorola
addresses higher than 80
.
Programming with DCC devices
Use the programming menu in your DCC Centre to program the decoder CVs in either
register, direct CV or page programming mode. It is also possible to program the decoder on
the main line using a DCC Centre.
Refer to the manual for your control centre for full instructions on the process.
Programming of long Addresses without the Programming Menu
For programming with a centre which does not support programming with an input menu, the
value for CV17 and CV18 must be calculated. Here is an example for programming the
address 2000.
•
Divide the addresses by 256 (2000:256 = 7 remainder 208).
•
Take the result (7) and add it to 192.
•
Program this value (199) into CV17.
•
Program the remainder (208) into CV18.
Important: Set Bit 5 of CV 29 to 1, so the decoder uses the long address.
