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 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
◆
Outputs
Address range
DCC 0-2047

Märklin Motorola 1-320
◆
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 central units, the decoder can be
◆
addressed with addresses 5 to 12 (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
