NOCH 66250, Manual

Page: 8 / 28

ATTENTION: The motor is not designed for non-stop operation. Do not connect the manual release pushbutton directly
to the transformer! Do not operate the decoder on an electroconductive base! Risk of short circuit and destruction!
For programming press the pushbutton on the decoder (see picture) before connecting the decoder to the current supply.
Please strictly adhere to the following procedure:
2. How to programme a turnout or signal address on the digital station
The decoder has to be connected to the main track, not to the programming track. Important: While programming please make
sure that neither a locomotive with address 67 in the Märklin data format nor a locomotive with address 67 in the
DCC/NMRA format are activated on the command unit. Please check this before you continue to programme. In addition we
recommend making a restart of the command unit without deleting the existing database (ATTENTION: Do not make a complete
reset of the system! Please follow the instruction manual of your command unit!). Switch off the power on the track (press button
“STOP”). Keep the pushbutton on the decoder (see picture) pressed when you switch on the power on the track again. The red
LED of the decoder flashes now. The decoder can only be programmed with an address group of 4 successive addresses
(Example: 1 - 4, 5 - 8, 9 - 12, etc.). The decoder automatically recognizes whether it is a
Märklin/Motorola or a DCC address. Now enter the address for the segment turntable as a magnetic item.
Important: The first address of the group of 4 successive addresses always controls the function. Send a switching command
and the red LED will go out (in our example: 1, 5, 9, etc.). Depending on the used command unit the highest
address which can be chosen in the Märklin/Motorola format is address 317 and address 2045 in the DCC format. Not all
command units send the complete address range. The decoder checks the switching commands while importing the address. It
may happen that you have to send the switching command several times, especially if various locomotives are activated in
different digital formats while importing. As soon as the red LED goes out, the programming of the decoder is finished. To
release the decoder it is necessary to change the digital format of the memorized magnetic item (segment turntable) on some
multi-protocol command units. For this purpose call up the magnetic item and change the data format (Märklin/Motorola <>
DCC/NMRA).
Once the decoder is correctly programmed you can choose the following functions:
Address 1 in a group of addresses: The 3 positions are approached sequentially same as by pressing the red pushbutton.
Address 2, 3 and 4 in an address group allow you to directly approach the 3 different positions. Example for addresses 5 to 8:
address 6 trips the first position, address 7 the second position (middle position) and address 8 the third position.
3. Märklin Mobile Station 60652 (firm locomotive address):
1. Install a locomotive with address 67.
2. Connect the red cable to the center track and the black cable to the track. Important: Pay attention to the polarity!
3. Press “STOP” on the mobile station (power OFF). Now keep the pushbutton pressed on the decoder (see picture 2) and
press again STOP on the mobile station (power ON).
4. Red LED goes on and out.
The decoder is now programmed with the locomotive address 67. The button “illumination” releases the function and the
positions are approached sequentially.
4. ROCO Lokmaus 2 (firm locomotive address):
1. Install a locomotive with address 67.
2. Connect the black cable to the track.
3. Send address: For this purpose press button F1 several times.
4. Keep the button pressed on the decoder (see picture) and connect the red cable to the track (power ON).
5. Red LED goes on and out.
The decoder is now programmed with the locomotive address 67. The button F1 releases the function (the three positions are
approached sequentially). Note: Please strictly adhere to this procedure to ensure that the address will be sent. Do not use the
button “STOP”.
5. You do not remember your decoder address and have to make a decoder RESET
In case you do not remember your decoder address, you can repeat the procedure previously described. If you have memorized
a digital address in your decoder but if you want to analogically operate the segment turntable directly with a model railroad
transformer, you have to cancel the digital address. For that purpose switch off the current and connect the pushbutton for the
analog release. Keep the manual release pushbutton as well as the button on the decoder pressed at the same
time and then switch on the current. Now the digital address of the decoder is deleted and you can release the decoder with the
manual release pushbutton.
