The accessory address of the signal A
is written to the address confi guration
variable relating to the fi rst function
output the signal is connected to. Up to
fi ve addresses (A

are used for switching signal aspects.
An Example
A single light signal shall be controled by a
Z1-8 decoder with
Signal
commands of accessory address 1.
Connect the signal to the decoder and
program
the
confi guration
according to the following table. The values
given in grey do not need programming
but they are written automatically when
programming the values written on while

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.)
