Configuration
Addresses
The decoder follows the addressing by
◆
output.
A freely selectable address can be assigned to the
◆
output.
The programmed address is used jointly by DCC
◆
and Märklin Motorola.
If you only want to assign addresses to the decoder, it
is easier to use the automatic
learning mode.
Calculation of CV values
As only values from 0-255 can be stored in a CV,
◆
the addresses must be divided into two CV values.
The addresses of the outputs of accessory decoders
◆
are stored as an 11-bit address, i.e. from a value that
can be represented by 11 bits.
A CV value consists of only one 8-bit value.
◆
To be able to save an address of an output of an
◆
accessory decoder, the first 8 bits of a total of 11
bits of the address are saved in a CV value and the
remaining 3 bits in another CV value.
The first 8 bits are referred to as 8 LSB
◆
The next 3 bits are referred to as 3 MSB
◆

Default setting
On delivery, the decoder is programmed with
◆
the internal address 4-11.
In some central units, the decoder can be
◆
addressed with addresses 1 to 8 (e.g. Märklin
Mobile Station 2).
In other control centers, the decoder is connected
◆
to the
Addresses 5 to 12 can be addressed (e.g. Roco
Multimaus with track box).
Determination of 8 LSB and 3 MSB
3 MSB= Output address / 256 rounded down 8
LSB= Output address - (3 MSB * 256)
Example
Output address 9
3 MSB= 9 / 256 rounded= 0
8 LSB= 9 - (0 * 256)= 9
Example
Output address 934
3 MSB= 934 / 256 rounded= 3
8 LSB= 934 - (3 * 256)= 166
Example
Outgoing address 270
3 MSB= 270 / 256 rounded= 1
8 LSB= 270 - (1 * 256)= 14
