A cassette is disclosed for use in combination with a host device, such as a photographic device, having a cassette chamber for receiving the cassette in an operative position, such that when the cassette is operatively positioned in the cassette chamber, an optically coupled interface is established between the cassette and the host device. This interface provides for establishing a two-way communications path between semiconductor memory circuits in a microcontroller within the cassette and a microprocessor, or computer in the photographic device. Thus, the computer in the photographic device can retrieve information stored within the memory of the cassette to automatically make appropriate adjustments within the photographic device. A source of power is carried by the cassette to operate the memory and the optically coupled interface. |
