stationary block decoder is selected for a specific block, then the power generated by
this decoder must be routed to the block. In order to establish the electrical connection
you have to specify an on-off switch (see section 2.5, “Signals and Accessories”) for
each stationary block decoder, which shall be used to turn on or off the connection between
the block and the decoder. In most cases a sequence of switching operations (e.g.
a sequence of several relays) must be operated to establish the connection between a
block and a stationary block decoder. In this case make use of the possibility, to assign
a set of operations (see section 12.3, “Operations”) to an on-off switch.
Whenever a block is reserved for an engine or train, then the Dispatcher searches an
appropriate stationary block decoder. If a decoder was found, then the on-off switch,
which is associated with the connection between the block and the decoder, is automatically
turned on. When the block is released, this on-off switch is automatically turned
off again.
If you have arranged your blocks correctly, then you do not have to take care of the dynamic
assignment of decoders to blocks and the routing of the electrical power from the
decoders to the affected blocks. This is done automatically by the Dispatcher.
Of course it is possible to arrange your blocks in a way, that one decoder can control
several blocks simultaneously, which are reserved for the same train.
