The invention relates to a method for reading programmes into a device
which processes data using a processor, according to a programme stored in
a programme memory. A programming device sends programme data to the
programme memory of the device to be programmed in the form of a data
stream. The inventive method comprises the following steps: a) activating
a light transmitter in accordance with the programme data, so that said
light transmitter generates digital light signals in accordance with the
programme data; b) receiving the light signals with a light receiver which
is permanently installed on the device to be programmed and c) applying
the signals of the light receiver of the device to be programmed to the
programme memory of the same. The invention also relates to a device for
carrying out this method.
