CV Programming
CV programming must be done on the programming track.
We recommend creating a fictitious locomotive for program-
ming 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.

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 configura-
tion on the Central Station. After that the programmed 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 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.
