Addresses
The decoder follows the addressing by
◆
output.
Freely selectable addresses can be assigned to
◆
the outputs.
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
◆

Address range
DCC 0-2047

Default setting
On delivery, the decoder is programmed
◆
with the internal addresses 4 and 5.
In some central units, the decoder can be addressed
◆
with addresses 1 and 2 when delivered (e.g.
Märklin Mobile Station 2).
In other central units, the decoder is delivered
◆
with the addresses 5 and 6
(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
