1. General Information
The 7286 Conventional Märklin Turntable
can be converted with the 7687 Digital
Retrofit Kit to the easy-to-use control of the
7686 digital turntable. The turntable does
not have to be removed from the layout or
taken apart for this conversion. Turntables of
other makes are in general not equipped,
as delivered from their manufacturer, for the
installation of the 7687 Digital Retrofit Kit.
The 7686 turntable can be used for conven-
tional and for digital operation. A 6020
Central Unit or a Control Unit 6021, and a
6040 Keyboard are required for digital con-
trol of the turntable. It is also possible to
control the layout with a computer (6050 or
6051 Interface) and with a track diagram
control board on a computer screen (Com-
board 60511).
By digitally controlling the turntable, each
existing track connection (spoke track) can
be accessed directly with the track indexing
feature. The turntable deck can be turned to
the next spoke track in single steps. At the
push of a button a locomotive on the deck can
also be turned 180° in either direction. The
special digital decoder and control electro-
nics are integrated in the turntable receiver
delivered with the unit.
Information:
The description before you explains in parti-
cular the use and operation of the digitally
equipped turntable.
Please note in addition the information on
the installation, on the operation of locomo-
tives on the turntable, and on maintenance
of the turntable in the current instructions for
the 7286 turntable!

2. Installation on the layout
The turntable receiver can be screwed di-
rectly onto the mounting posts under the turn-
table pit or next to the turntable on the layout
base board. The 30 cm (1') ribbon cable is the
maximum distance that the receiver can be
from the turntable. The existing terminal
strip on the 7286 Conventional Turntable is
no longer needed when converting this turn-
table with the 7687 Digital Retrofit Kit.
