Tip: Before starting to program the locomotive decoder you should
connect the motor to the decoder. Otherwise there is no confirmation
signal from the central unit.
Connecting the LEDs
The function outputs of the locomotive decoder switch against decoder
ground. For that reason you must connect the cathode (-) of the LED to
the output of the relevant function.
!
Caution:
If you use light-emitting diodes (LEDs) you must always operate them
via a series resistor.
LEDs are available in many different models. There are LEDs with 2-5
mA, but also LEDs with 15-30 mA power consumption. The series
resistor limits the current flow of the LED and will need to be calculated
for each model. Ask for the max current rating when buying your LEDs.
You can connect up to 5 LEDs in parallel to each output. In this case every
LED must have a series resistor of its own. If you connect several LEDs to
one output in series, only one series resistor is needed. The number of
LEDs connected in series to one output depends on the digital voltage.
You can determine the number of the LEDs that can be connected in
series to one output from the following formula:
(number of LEDs + 2) x 1,5 < digital voltage
Fixing the locomotive decoder
After completing all connections fix the locomotive decoder with double-
sided adhesive tape, for example.
