Abstract
A flash generator is capable of identifying which type of flash head and flash head extension cables that is connected to the flash generator. A flash head and flash head extension cable can be identified by the flash generator. The flash generator provides a power supply to a flash head. Further the flash generator includes a first current generator for charging the capacitor. The flash generator further includes a second current generator or a voltage generator connected to an output of the flash generator and arranged to provide a current or a voltage to create a voltage UID over a component in a flash head or a flash head extension cable connected to the flash generator. Processing means are arranged to identify the flash head or the flash head extension cable by the measured voltage UID.
