Model Railway Control Unit
Example 1: You switch turnout number 1 during the programming process. All eight outputs of the switch decoder are then pro-
grammed in ascending order to turnout numbers 1 to 8.
Example 2: You switch turnout number 2 during the programming process. All eight outputs of the turnout decoder are also pro-
grammed in ascending order to turnout numbers 1 to 8, because turnout number 2 is in the same group of four as turnout number 1
from the first example.
Example 3: You switch turnout number 10 during the programming process. All eight outputs of the turnout decoder are then pro-
grammed in ascending order to turnout numbers 9 to 16: first the group of four from 9 to 12 for the first four outputs, followed by the
group of four 13 to 16 for the next four outputs.
The first output is therefore always numbered at the beginning of a group of four. The beginning of the groups of four is calculated
automatically when programming the switch decoder.
Factory setting: numbered in ascending order from 1.
6.1.2 Option 2 – Program address for outputs 5 to 8
This option is used exclusively to program the second decoder address for outputs 5 to 8. Outputs 1 to 4 remain unchanged. Only use
this option when you do not want to number all 8 outputs of the decoder consecutively.
1. Keep the programming button held down for at least 3 seconds until the white "Program" LED begins to flash. Then release the
programming button.
The white "Program" LED will then flash normally once (short, pause; short, pause; etc.), and the green LED will be lit continu-
ously.
The switch decoder is then in "Configuration mode, option 1".
2. Keep the programming button held down for at least 3 seconds again until the blue "Status" LED and white "Program" LED
begin to flash together. Then release the programming button again.
The white "Program" LED will then flash normally twice (short, short, pause; short, short, pause; etc.), and the red LED will be
lit continuously.
The switch decoder is then in "Configuration mode, option 2".
3. Now switch a magnet accessory of your choice. The magnet accessory can be switched via the Z21 app or another input
terminal, such as the multiMAUS.
4. As soon as the switching command has been notified by the switch decoder, the new address is applied to outputs 5 to 8 and
configuration mode is exited automatically. The white LED goes out and the blue LED indicates normal mode.
The turnouts numbers for outputs 5 to 8 are programmed here again exclusively set up in groups of four.
Factory setting: numbered automatically consecutively again from output 4.
6.1.3 Option 3 – Set addressing mode
This option is used to select between "ROCO" or "RCN-213" turnout addressing mode.
1. Keep the programming button held down for at least 3 seconds until the white "Program" LED begins to flash. Then release the
programming button.
The white "Program" LED will then flash normally once (short, pause; short, pause; etc.), and the green LED will be lit continu-
ously.
