ABSTRACT:
A control unit for model vehicles, such as model railway trains, model automobiles, etc. For independent operation of several model vehicles on a common electric circuit, it is known to allocate to each model vehicle a receiver coded in relation with hardware and controlled according to a binary word consisting of an address part and a data part. Control units of this type, however, have the disadvantage that they cannot be operated on analog electric circuits. With the invention, a control unit is proposed which independently switches off the digital control logic in the case of a change of the model vehicle from a digital trackage to an analog trackage, and enables operation of the model vehicle via an amplitude-controlled or pulse width-controlled analog signal.
