In order to set the address via the programming jumper / push-button perform the following
steps:
1. SD-34: Bridge the two pins of the programming connector JP1, by putting on the jumper
included in the package. Take it away as soon as the LED flashes.
SD-34.2: Push the programming push-button on the PCB. The LED flashes.
2. Set one of the addresses from the quadruple accessory decoder address block you want to
use for switching the connected accessories at the control unit (e.g. address "10" from the
quadruple accessory decoder address block 9 – 12). Perform a switching command for the
chosen address.
3. As soon as the LED goes out, the decoder has taken over the new address.
Setting the decoder address via CVs
Instead of setting the address using the programming button, you can alternatively set it by
programming the CVs with a DCC control unit. The turnout addresses, via which the switching
commands are sent, result as follows:
Decoder address x 4 = highest address of the quadruple accessory decoder address block
Note: For the control of the decoder in Motorola format "255" is the highest decoder address
(= turnout address 1020).
Note: With some control units the numbering of the turnout addresses does not start with "1" but
with "0". The addresses assigned to an address block are shifted accordingly.

Remarks and tips
The "base value" of the decoder address results
from multiplying the input value by 256.
The decoder address results from the addition of
the "additional value" to the "basic value".
