Installing the Decoder
You may change the voltage setting by exchanging a resistor. An
SMD resistor is required. Type 0805, power rating 0.125W:
R124
R125
Rear light
Head light
UVAR (1,5-3V)
Voltage
R124
1.5V
33 kOhms
2.5V
unsolder
3.0V
48 kOhms, unsolder R125
The maximum load of the UVAR output is 500mA.
6.9.2. Using LEDs
If you like to use LEDs, then a resistor must be wired in series with
the LEDs. It should have a rating between 470 Ohms and 2.2 kO-
hms. Running the LEDs without this resistor will lead to their im-
mediate destruction! Unlike lightbulbs, LEDs are polarity-sensitive.
The minus (cathode) end of the LED is connected to the function
output, the plus (anode) end is connected to the blue (function
common) wire.
Please to not forget to switch the respective function output to
LED mode. This will ensure a prototypical presentation of all light
effects. Please refer to chapter 12.3. for more details.
