Decoder Installation; Cv Programming - Märklin 74466 Installation

Decoder Installation

The following work steps may only be done in a voltage-free
work environment:
• Plug the cable included with the decoder (pay attention to
the track system) in the socket provided for it – see page 36
(Märklin). Now follow the illustrated instructions.
The digital installation decoder for three-way turnouts requires
2 addresses. The sequential address is automatically assigned
to the first address set. Please note that this sequential address
may not be use for any other accessories. Failure to adhere to
this rule may lead to malfunctions.
See the section "CV Programming" for changes to other charac-
teristics in the fx (MM) protocol using CV programming or to the
DCC CV programming.
Note: Settings with the DIP switches are to be only when the
voltage is turned off. The digital installation decoder does not
recognize the current switch settings until the voltage is turned
on.
Starting on page 39 you'll find the table for setting addresses
with DIP switches.
See page 28 for information on installing the digital installation
decoder in three-way turnouts.

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.
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 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.
