Patent ID: 8483237

Claim:
Communication module (KomM) for the connection of electric host devices (HG) with respectively individual physical interface to an external network (N 1 , N 2 ), wherein the communication module (KomM) is connectable with the host device (HG) by means of an interface (DHI) and by means of an adapted network connector (NV) with the respective external network (N 1 , N 2 ), wherein the communication module (KomM) provides at least two physical interfaces, of which one is implemented as a serial interface, by means of which serial communication between the communication module (KomM) and the host device (HG) is made possible and wherein the interface (DHI) features at least one electric connector by means of which at least two physical interfaces are selectable by means of the host device (HG), wherein the at least one electric connector (PIN 3 , PIN 18 ; PIN 3 , PIN 28 ) is a component of the serial interface (UART) of the communication module (KomM), wherein the communication module (KomM) features a signature that is readable by the host device (HG) by means of the serial interface and contains information regarding the physical interfaces that are implemented in the communication module (KomM) as well as communication parameters, and wherein the identification of the communication module (KomM) as well as the selection of the at least one physical interface that is suitable for the host device (HG) is executable by means of serial communication via the serial interface by means of the host device (HG).
