Any signal can be controlled by an input
key connected to a function output of the
Qdecoder using a 220 Ω resistor. Use one
of the modes 226 or 227 for the function
output for reading key input. Mode 227 is
used when connecting a LED in parallel to
the key. The LED might be used as signalling
LED on the control desk for example. (See
chapter Taster und Schalter on page 106 for
details.)

In general three different kinds of signals
may be distinguished: main signals can

Many important main lines are now
signalled for movements in both directions,
and special light signals are provided for
4
movements on the right-hand track. These
signals are mirror images of the usual
signals, and are placed on the right of the
track instead of on the left. The aspects
are the same, except that the lights are
clignotants, or blinking. One must distin-
guish this from movements against the
current of traffi c, which is quite another
thing, and always extraordinary.
