CV Programming
CV programming must be done on the programming track.
We recommend creating a fictitious locomotive for programming
purposes. Values in parentheses are the factory settings.
The turnout lantern connected to the digital installation decoder
will blink as a control check during the data transmission.
The programming can be done optionally with fx (MM) or DCC.
In fx (MM), we recommend setting the address by means of DIP
switches (see 39ff).
fx (MM)
Before doing any programming, the turnout to be programmed
must be switched with the Keyboard. After that the CVs are
changed immediately with the Control Unit or the CV configu-
ration on the Central Station. Immediately after that, switch the
newly programmed turnout again with the Keyboard. At this
point the programming is accepted and is functional.

The procedure for programming with the 6021 Control Unit is the
same as locomotive programming (www.maerklin.de -> Service

Setting and generating addresses larger than 255:
Example: Address 1044 -> 1044:256=4,078125 . The value before
the comma (4) is to be entered in CV 9. The value after the com-
ma (0,078125) is multiplied by 256, 078125x256=20. The value of 20
that is generated must be entered in CV 1.
