Abstract: A communications module including an electrical interface for operatively connecting the communications module to an electric device is disclosed. The electric interface enables data communication between the communications module and the electric device in either a serial mode or parallel mode. The communications module includes: one or more electrical connectors arranged in the electric interface, a Dual Port RAM is connected to the electrical interface for providing parallel transfer of data through the electrical interface, and a control unit connected to at least one of the one or more electrical connectors, wherein the control unit is adapted to determine the value of one or more signals applied on the at least one of the one or more electrical connectors and enable either serial or parallel data communication through the electrical interface depending on the value of the one or more signals.
