Function modul

Light on / off

General

A function module transmits commands to a DC-Car decoder by means of a short range IR communication (10-25cm).
There are 8 outputs available. Each of them sending a specific DC-Car command constantly.
These commands are send to IR LEDs which are placed in or beside the road.
The function module commands are working on each DC-Car without the use of their DCC adress.
So each passing DC-Car vehicle will react on the received signal.
As example: an IR LED send a "Headlight ON" command in front a tunnel entrance.
When leaving the tunnel a "Head light OFF" command is send. Now all cars passing the tunnel switch ON and OFF their head lights automatically.
Naturally it is also possible to send commands via switches or relays to the IR LEDs which brings a various vehicle traffic like in real life.

By using the dip switch on the function module, various command combinations are available on the eight output.
The ammount of combinations is still growing over the years (see the listing below).

Supply voltage can be 12V - 16V AC or 12 - 16V DC.
The outputs offer a current of max. 1A total, which brings the max. amount of connected IR LED to over 50 which is mostly more than enough to control an everage layout.

By using a diode-circuit with 1N400x diodes it is possible to transmit multiple commands on one single IR LED.
The Function module can be combined with S4-Car-Servodecoders for instance to get automatic direction indicators and speed changes. It can also be comined with our traffic light decoder to controll the flow of traffic on your layout.

IR-LED on/in the street

Mounting of the IR-LED on the site:

The IR-LED is placed in or nearby the street in such a way that the cars can "see" the IR-light, emitted by the LED and execute the transmitted function at the intended place.
The IR-LED must be adjusted in a way, that the approaching vehicles can "see" it. On a straight line the vehicles detect the desired function in a distance of approx. 5 - 15cm from the LED
Sometimes a IR-LED influences the traffic on a parallel line too. In this case you can either increase the series resistor to decrease the range of the IR-signal or mount the LED into the street in a way that its IR beam lights vertical only. If you do the second, please use LED with a wider angle of reflection. Distance of the LEDs shoul be 5 - 10cm, but it is highly recommended to test it in every single case!

When the car passes the first LED it will start slowing down - an when it reaches the second LED in most cases it is that slow,
that it can come to a stop right there.
Using cars with a significiant lag it can be neccessary to use more LEDs

The LEDs are connected to the same connector, each ussing its own series resistor.

Remote control

Instead of function module I:
To make it easy for you we produce a battery powered remote control: MF plus.
The Plus version has build in test functions which can be used with the optional test set. These test functions have proved to be very usefull when building vehicles.
You can test polarity and working of LEDs as well measuring short circuits.
With the foto transistor (include in the set) your able to check the working of the IR LEDs at the back of the vehicles as well IR signals along the road.
And with the remote control it self your able to test the fototransistors at the front and the correct operation of the decoder and vehicle.

Function decoder

Function decoder

Using the function module in DCC mode with a digital center

A function module can be extended with a digital input. After extension the function module becomes a function decoder.
This enables switching the 8 outputs from a digital center using the addresses 1-8, (9-15), etc.
Note: All LEDs on each output are switched ON or OFF together! Especially in combination with other functions, like switching the light output makes sense.
The decoder can be used in the same way as the module, but offers the possibility to switch the 8 outputs separately by means of 8 digital addresses.

- central switching of "stop" for emergency OFF
- central switching of light for day-/night mode

Direction indicators are controlled by feedback sensors of junctions, lights are controlled by a digital addresses

Day/night control with a function decoder other functions still can be controlled by switches
