ABSTRACT:
In a system comprising a transmitter, a receiver, and a module, a communication object is transmitted from the transmitter to the receiver which comprises a payload data block containing data for generation of a command to the chip module obeying a communication protocol specific for the chip module, and a parameter block comprising at least one instruction which defines how the generation of the command to the chip module is to be performed, thereby facilitating a control and change of the communication protocol between the receiver and the module.
