ABSTRACT:
A device performs a synchronization between flasher frequencies of flasher devices and a central flashing frequency of a central control device at times when a data transmission device is in the active state. For a synchronization, a correction signal is determined in the central control device from a deviation of a phase of the flasher frequency relative to a phase of the central flashing frequency and transmitted to a flasher control device which modifies the flasher frequency phase in response to the correction signal. Following the modification of the flasher frequency phase the data transmission device is switched back once more into an idle state. This offers the advantage that a synchronization of flasher devices with a central control device can be performed, whereby a data transmission device does not need to be permanently active and can therefore be used in a power-saving way.
