Signal aspects

, see Switching commands in conventional DCC
basic
format, and for the column DCCext, see Switching com-
mands in the new DCC
ext
format and Z21.
The diagrams shown here only display a selection of possible signal screens. The examples are intended to explain the logic within
this signal conguration, and of course signal screens can also be connected and operated with a reduced number of lamps. The same
applies as for the prototype: do not switch a signal aspect if this is in principle available, but cannot be correctly displayed by the signal
actually connected because the lamp is not equipped. The user is responsible for only using expedient signal aspects which can actually
be presented.
