Abstract: A method and apparatus for activating a remote light source in synchronization with an indication provided from a camera. A transducer is coupled to the external electrical connector of a conventional camera in order to convert the electrical signals that are output from the camera into an alternative form (e.g., optical signals). A different transducer is coupled to the external electrical connector of a remote light source, such as a photographic strobe. The light source transducer receives the signal from the camera transducer and converts the signal back into one or more conventional electrical signals to activate the remote light source. A light source activation signal and a light source modulation signal are multiplexed onto a single communication channel. A first indication is provided on the communication channel to activate the remote light source (i.e., cause the remote light source to emit light).
