8. CV Programming
CV programming must be done on the programming track.
We recommend creating a fictitious locomotive for pro-
gramming 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.
fx (MM)
Before doing any programming, the turnout to be program-
med must be switched with the Keyboard. After that the CVs
are changed immediately with the Control Unit or the CV
configuration on the Central Station. After that the program-
med turnout is to be switched 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 ->

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