The TurnTable-Decoder TT-DEC receives the power supply via the two clamps at the
very left side of the 11-poles connection clamp. The voltage can be between 16 and
18 Volt~ (alternated voltage of a model railway transformer). Both clamps are marked
accordingly.
The decoder receives the digital information via the third and fourth clamp (counted
from the left side) of the 11-poles connection clamp. Supply the digital information
directly from the control-unit or from a booster respectively from the digital ring
conductor “switching” which has been connected to all accessory decoders. To assure
that the TT-DEC receives interference-free data do not take the digital information
directly from the rails.
One of the two digital clamps has been marked with red and K and the other has been
marked with brown and J. The colors red and brown respectively the marking J and K
will be used by most command stations.
The red LED will flash after switching-on the power-supply until the decoder
recognize a digital voltage at the digital input. Then the red LED will glow constantly.

All Fleischmann turntables and the Roco turntable 35900 contain a 5-poles flat
ribbon cable. The two yellow wires on the right side are for the supply to both bridge
rails. For a simple connection this wires can be connected to the digital ring conductor
“drive”.
If you want to change the polarity of the bridge rails automatically via the TurnTableDecoder TT-DEC (problems of the reverse loop by bridge turning of 180º) the two wires
have to get the digital current supply from a permanent power switch unit DSU
(DauerStromUmschalter). Additional information is available within the chapter
“Change the bridge track polarity on Fleischmann turntables”.

The direction to connect the plug to the 6-poles pin bar of the TT-DEC has to assure
that the flat ribbon cable shows away from the decoder. The cable should not be
twined around the plug. The connection to the turntable is correct if the brown single
wire of the flat ribbon cable shows in direction to the 11-poles clamp bar.
The manual turntable switch, supplied together with the Märklin turntable, shall not be
connected in this case.
For an installation of the decoder at a larger distance to the turntable you can use our
extension cable “Kabel s88 0,5m”, “Kabel s88 1m“ or “Kabel s88 2m” with a length of
0,5 meter, 1 meter respectively 2 meter. For a correct installation of the extension you

4. Programming the TurnTable-Decoder TT-DEC:
For the first start please take care that you follow exact the sequences of the
programming as described below.
4.1. Programming of the basic address and the data format:
The TurnTable-Decoder TT-DEC will be controlled by accessory addresses (turnout
addresses) which will be used as well for switching of turnouts or signals.
-6-
TT-DEC – Manual
The command structure of the TT-DEC is compatible to the commands of the Märklin
turntable-decoder 7686. It does not matter if you actual want to digital control a Märklinor a Fleischmann turntable.
The indication of the data format for the control of the TurnTable-Decoder TT-DEC from
the command station (Märklin-Motorola or DCC) is not required. The data format will be
automatically recognized from the TT-DEC during the following programming process
of the basic address.
With reference to the Märklin turntable decoder 7686 is the TurnTable-Decoder TTDEC able to use two address sections. If you use a PC-model railway software for the
control of the turntable you find mostly for the two address sections the indication of
14 and 15. With this selection is it possible to operate 2 turntables via 2 TurnTableDecoders TT-DEC on your layout.
The address section 14 covers the addresses 209 till 224 and the section 15 covers
the addresses 225 till 240. Only by using the full capacity of the turntable with 48 track
connections all addresses within the selected address section will be required.
If you use a multi protocol command station which is able to send several data formats
you have to take care that all addresses within the selected address section will be
adjusted uniform to Märklin-Motorola or DCC.
A table showing the coherence between address section, address and turntablefunction can be found at chapter 4.7. “Programming- and Control-Table” within this
operation instruction. This table gives you as well the information about the symbols (if
required) your model railway software uses for the various turntable functions.
Programming process:
1. Switch-on your digital-layout and the TurnTable-Decoder TT-DEC. If you want
to perform the programming of the TT-DEC via your model railway software you
have to switch-on those and adjust the turntable if required at first in
accordance to the relevant instruction of the software. It is important that your
model railway software supports the Märklin-turntable decoder 7686 because
the TT-DEC is compatible to the commands of the Märklin decoder.
2. Please press shortly 1-times the key S1 which is located at the right side next
to the TT-DEC heat-sink. Now the yellow LED will flash.
3. Send now several times the command >Drehrichtung< (Turning Direction) at
clockwise direction or anti clockwise from your command station or from your
model railway software in accordance to the programming- and control table
(chapter 4.7.). If the TT-DEC has recognized the command after several
sending intervals this will be indicated by a switched-off yellow LED.
4. The TT-DEC will leave the programming mode automatically. All three light
emitting diodes will glow.

TT-DEC – Manual
4.2. Adjusting the turntable bridge-speed and the cycle-frequency:
Because every turntable contains different mechanical and electrical characteristics
is it required to adjust a safe and realistic operation via the TurnTable-Decoder TTDEC with two potentiometer.
The factory setting of both potentiometers is in middle position the arrow of the
setting slit shows to the top (12:00 o`clock). The potentiometer P1 for cycle
frequency (illustration 1) can be adjusted from the right side after detaching the
housing cover. The potentiometer P2 for the turntable speed (illustration 2) is
located at the rear left side next to the heat sink.

Adjustment:
1. Set both potentiometers into middle position by using a suitable small screw
driver (12:00 o`clock, factory setting) because this position covers the
requirement of most turntables.
2. For a 180 degree turning of the turntable bridge send now the command >Turn<
from your command station or from your model railway software in accordance
with the programming- and control table (chapter 4.7).
3. Each possible track connection should initiate a clicking noise and the bridge
shall turn by 180 degree.
4. If you hear no regular clicking for each track connection the bridge will stop
early and the red LED flashes.
Then turn the potentiometer P1 “frequency control” onto position 11:00 o`clock
and send the command >Turn< again. If the bridge will still not turn by 180
degree adjust the “frequency control” potentiometer onto position 10:00
o`clock.
On this way you will find the optimal position of the “frequency control”
potentiometer to assure that the bridge will turn by 180 degree after each >Turn<
command.
-8-
TT-DEC – Manual
5. With the potentiometer P2 “turntable bridge speed” is it possible to change the
turning speed of the bridge. The clicking of each track connection shall be
audible. Change the turning direction of the bridge with the command
>Drehrichtung< (turning direction) and correct the turning speed with the
potentiometer P2.
6. Control: After further >turn< commands in both directions with and without
locomotive the turntable bridge should turn each time by 180 degree to the
same track connection. If necessary repeat the adjustment as described under
1 to 5 with a little higher turning speed. If the turning bridge is turning generally
unevenly please check the mechanical components of your turntable.
4.3. Programming track connections:
Please attend:
The adjustment of the turntable bridge speed and the cycle frequency has to be
completed in accordance to section 4.2 to assure a reliable turning of the turntable bridge
by 180 degree by each >Turn< command in both turning directions before starting
with the programming of the track connections.
By programming the track connections you should prepare your TurnTable-Decoder
TT-DEC to be able to recognize all available track connections and turn the turntable
bridge to the required track connection during the operation. During the
programming process please define one track connection as track 1 as a so-called
reference track.
Programming process:
1. Press shortly the key S1 2 times. The green LED flashes.
2. Send now the command >Input<. The red LED will be shortly switched-off and
the turntable bridge turns eventually to the last programmed reference track.
3. Turn now the turntable bridge with the commands >Step< (clockwise or anti
clockwise) to the track 1 (reference track).
4. Send now the command >Clear< to store the position track 1 (reference track).
The red LED will be switched-off shortly.
5. Turn the turntable bridge with the command >Step< clockwise to the next
required track connection. Please consider eventually as well single opposite
track connections.
6. Store the track connection with the command >input<. The red LED will be
switched-off shortly.
7. Prepare further track connections on the same way.
8. If you have completed the programming of all track connections send the
command >End<. The turntable bridge will turn to track 1 (reference track)
and the programming mode will be automatically finalized. If the turntable
bridge will not return to the defined reference track you have to repeat the
programming process.
-9-
TT-DEC – Manual
Programming Sample
According to the programming sequence item 3 the turntable has been turned into the
reference position. The bridge will be situated in level with the little housing on the left
side.
With the command >Clear< the position of track 1 (reference track) will be stored
(programming sequence item 4).
With the command >Step< clockwise the bridge will turn to the next available track
connection. This will be a single opposite track connection (track 2). With the
command >Input< will be the track connection 2 stored. (programming sequence
item 5 and 6).
With the command >Step< clockwise it will go-on to the track connections 3, 4, 5 and
6. Each track connection will be stored via the command >Input<.
The track connection 6 is the last track connection to be programmed because this
is the last track connection before the bridge will stay at the next >Step< clockwise
again on the reference track, but turned by 180 degree (the little house will be then
be located on the right side).
Therefore shall be additionally the command >End< transmitted at the track
connection 6. The turntable will turn to the track 1 (reference track) and the
programming mode will be left automatically (programming sequence item 8).

If Fleischmann or the Roco turntables 35900 will be used on a digital layout with 2conductor track the four track contacts of the bridge, which connect electrically the
bridge track with the track, shall be removed.
Alternatively is it possible to isolate each rail on both sides behind the track
connections.
If the bridge track has been electrically separated from the track connections by using
one of the above methods is the constant supply with digital current of all tracks to
the turntable possible. A constant supply of the tracks with digital current can be
recommended because on this way is it possible to switch specific loc-functions on or
off even inside the locomotive shed.
But if the turntable bridge turns by 180 degree there will be a short circuit in case the
polarity of the bridge track will not be adapted to the polarity of the contacted track
connections.
The TurnTable-Decoder TT-DEC is able to change the polarity of the bridge rail. For
this purpose will be the TurnTable-Decoder combined with a permanent power switch unit
(DauerStromUmschalter) DSU.
The permanent power switch unit DSU has to be connected with the clamps “G”,
“COM” and “R” to the TurnTable-Decoder TT-DEC as shown at the below sample
connection. The bridge track receives digital current via the DSU.

At the upper half circle (dotted line) will be always the red digital cable connected to
the first rail, looking at the wiring in clockwise direction.
If the turntable bridge is passing the parting line between the two wiring sections is a
change of the polarity of the bridge track required because the turntable bridge rails
get digital current supply as well. This can be done by the TurnTable-Decoder TT-DEC
via the permanent power switch unit DSU if it knows the parting line.
Programming sequence:
1. Press shortly 2-times the key S1. Now the green LED will flash.
2. Turn the turntable bridge with the command >Step< clockwise to the track
segment with the imaginary parting line. The position of the turntable bridge
shown at the PC screen or on the display does not matter provided that
- 12 -
TT-DEC – Manual
the adjustments will be carried out via your model railway software or via your
command station with turntable indication.
3. Send the command >Drehrichtung< (turning direction) clockwise or anti
clockwise. The position of changing the polarity will be stored and the
programming mode will be closed. The turntable bridge will turn
automatically to the track connection 1.
4. Control: Send the command >Turn<. If the turntable bridge is passing the
parting line the red LED will shortly switch off. If already a permanent power
switch unit (DSU) for the change of polarity of the bridge track has been
installed to the TT-DEC the relay of the DSU relay will give a click.
4.5. Synchronizing the reference track:
If the indication of the turntable bridge position of the model railway software or on
the display of the command station does not conform to the real position of the
turntable bridge is it possible to carry out a synchronization process.
Synchronization process:
1. Press shortly 1 time the key S1. The yellow LED will flash.
2. Turn the turntable bridge with the commands >Step< (clockwise or anti
clockwise) to the track 1 (reference track). The position of the turntable indicated
on the PC screen or on the display does not matter.
3. Send the command: turn directly to track 1. The turntable bridge does not
turn. The turntable symbol on the screen or on the display indicates now also
track 1. If the position of the control housing is not correct please send again
the command turn directly to track 1.
4. Send now the command >Drehrichtung< (turn direction) clockwise or anti
clockwise. The synchronization process is now completed and the yellow
LED will be switched off.
4.6. Special function: Turntable test / Factory setting:
4.6.1. Turntable test:
Press the programming key S1 approx. 4 seconds until the red LED will switch off.
The bridge will turn by 360 degree after releasing the key and will stop shortly on
each programmed track connection.
4.6.2. Factory setting:
If the programming-key S1 will be depressed for 2 seconds during switching-on the
TT-DEC, all adjustments will be deleted and the factory setting will be restored (basic
address 225, data format DCC, all 24 respectively 48 track connections are
programmed in accordance to the adjusted type of turntable re. chapter 2).

TT-DEC – Manual
5. Feedback reports:
The Turntable-Decoder TT-DEC is able to send the information “position reached” and
“bridge track occupied” to the feedback modules. Those feedback information can
be used by a digital command station or a model railway software for further
automatic control operation of the turntable.
After the turntable bridge reaches the wanted position the TurnTable-Decoder
TT-DEC creates a feedback signal on the 2-poles clamp KL5 marked with “feedback”
for the evaluation of the model railway software.
The information “bridge track occupied” will be realized by the 3-conductor rail via a
contact rail (one isolated bridge rail) and by the 2-conductor rail via a track
occupancy report by use of current measurement.
With reference to the installed turntable and digital system there will be different
feedback modules used for the two feedback information “position reached” and
“bridge track occupied”.
The (colored) wiring samples on the following pages and further samples for the
thematic feedback can be found as well on our Web-site at the section “sample
connections” for the Turntable-Decoder TT-DEC.
