Basic connection of functions
The individual functions are all connected in accordance with the
same principle: From the decoder output to one function pole, and
from the other function pole to the blue decoder wire. Alternatively,
the blue wire can be substituted by a connection to a track
connection (red or black wire).
If a track connection is used instead of the blue wire for
Outputs A and B, then CV49 must be set to polarity-
independent lighting (CV 49 = 0)!
Please note that LEDs are polarity dependent. If a function output
is to be connected to an LED, note that the function output is
negative and that the blue wire is the positive. If you want to
connect LEDs to the LF101XF, do not forget voltage limiting
resistors as the Blue wire is one volt less then full track voltage.
You can install several LF101XFs in the same vehicle or you can
use the LF101XF in the same locomotive as a locomotive
decoder. If you install multiple decoders in the same locomotive,
make sure that you program the decoders separately; before
installation.
