Introduction/Safety instruction:

You have purchased the 4-fold decoder M-DEC-MM for motor

driven turnouts for your model railway as a kit or as finished

module. The M-DEC-MM is a high quality product that is

supplied from the Digital-Professional-Series of Littfinski

DatenTechnik (LDT).

We wish you having a good time using this product.

The decoder M-DEC of the Digital-Professional-Series can be

easily installed and used on your digital railway.

The colored dot on the receiver device indicates to which

digital system the decoder can be adapted.

In case the receiver device is marked blue the M-DEC will be

suitable for the DCC Data format, used for instance at the

systems of Arnold-Digital, Intellibox, Lenz-Digital Plus,

Roco-Digital, TWIN-CENTER, Digitrax, LGB-Digital, Zimo,

Märklin-Digital=, EasyControl, KeyCom-DC, ECoS and

DiCoStation.

In case the receiver device is marked red the decoder is

suitable for Märklin-Digital~ respectively for Märklin-Motorola

layouts.

The finished module comes with 24 month warranty.

• Please read the following instructions carefully. Warranty will

expire due to damages caused by disregarding the operating

instructions. LDT will also be not liable for any consequential

damages caused by improper use or installation.

Connecting the decoder to your digital

model railway layout:

• Attention: Before starting any installation work switch off

the supply voltage to the digital installation by

disconnect all transformer power plugs of the main

supply.

The decoder receives the digital information via the clamp

KL2. Connect the clamp with a rail or even better connect the

clamp directly to the command station or to a booster

assuring supply of digital information free from any

interference.

Pay attention to the mark at clamp KL2. The color markings

'Black/Schwarz' and 'Red/Rot' next to the clamp are used for

Arnold-Digital (old) and Märklin-Digital= .

Other systems uses the letters 'J' and 'K'.

If you use the decoder with Märklin Digital~ components or

with Intellibox you have to connect the digital wires to 'red/rot'

and 'brown/braun'.

The decoder receives the power supply via the two poles

clamp KL1. Voltage in the range of 12 to 18V~ is acceptable

(alternate current output of a model railway transformer) or

15...24 V= (direct current from a switched mode power supply).

If you do not want to supply power to the decoder M-DEC from

an external transformer you can connect the clamp KL1 to

KL2 with two wires. In this case the decoder will get the power

supply complete from the digital system.

Programming the decoder address:

To program the decoder address a motor driven turnout has to

be connected to the output 1 (clamp KL9)of the decoder.

• Switch on the power supply of your model railway.

• Depress the programming key S1. Do not touch the

integrated circuits of the pc-board because any electrostatic

discharge can destroy the IC`s.

• The turnout drive connected to output 1 will now move a

little every 1.5 seconds. This indicates that the decoder is in

the programming mode.

• Is the motor not moving it is possible that the motor drive

contains directional diodes. In this case switch off the power

supply and turn around the two connection wires on output

1. After switching power on the turnout drive should move of

a 1.5 second interval.

• Depress now one key of the key group to be assigned to the

decoder. For programming the decoder address you can

also release a turnout switch signal via a personal

computer.

• Remarks: The decoder addresses for magnet accessories are combined in groups of four. The address 1 to 4 build the first group. The address 5 to 8 build the second group etc. Each M-DEC decoder can be assigned to any of these groups. Which turnout of a group will be activated for the addressing does not matter. Accessory: If the decoder has recognized the assignment correctly the connected turnout will move a little faster. Afterwards the movement slows down to the initial 1,5 seconds again.
