Wireless trailer
Wireless Connect
To pull a trailer with its own decoder so far were at least two wires
necessary.
see trailer decoder
It can also be the data transmission via an infrared connection.
This is also a way to more easily decouple the trailer, even to reconnect.
How wireless transmission works
Data is sent to the trailer via the serial output of the decoder.
The trailer signal is taken from the decoder via a series resistor of 220 ohms and transferred to an IR LED.
This LED is above the coupling of the tractor and radiates towards the towing eye. The LED must be mounted at an angle of approximately 45 degrees.
In the triangle is the IR phototransistor. This is located directly behind the towing eye.
Max. Distance to the IR-LED not more than +/- 1 cm!
For the phototransistor, a special type with a large reception range has been selected.
In the trailer comes the IR amplifier (IRVA), which is connected to the serial input of the decoder.

It should be clear that the trailer has its own battery, on / off switch and charging port
must have.
But it is even better! 'In'
A magnetic clutch with reed switch that automatically shuts off the trailer decoder
when the trailer is disconnected. This looks like this:
Torrent
'1 magnet 2 metal 3 reed connection 4 reed switch'
How it works with automatic shutdown
The reed switch is closed by the magnet and turns on the trailer decoder.
When the trailer is suspended, the magnetic field is interrupted.
A metal filler ensures that the magnetic connection is strong enough
to pull the trailer.
'Components required for the trailer:'
1x trailer decoder:
DC05-A for 3.6V battery
1x 3 times NiMH or LiPo) or
DC05SA 1.2V or 2.4V battery
1x NiMH or 1 double NiMH
1x IRVA Module: Infrared Amplifier
1x lights for the back of the trailer single LED
or 1 x RLT-IR backlight carrier with IR-LED
'Parts for the tractor:'
1x IR-LED
1x 220 ohms Resistor
'Parts of the magnetic coupling:'
1x magnet 3x1 cylindrical
1x reed contact
possibly extra:
1x on / off switch
1x charging socket BU3
