Methods for configuring a source apparatus and apparatuses for implementing the same

An apparatus comprising:

• a memory;
• and
• a processor operatively coupled to the memory, wherein the processor is configured to perform an operation for configuring a source apparatus adapted for processing an analog electrical output signal output to a receptor apparatus, the source apparatus being electrically coupled to the receptor apparatus through an output interface comprising a first and second output signal terminals of the source apparatus;
• the operation comprising:
• Configuring the output interface of the source apparatus to be an analog current output;
• Obtaining one or more measured voltages respectively corresponding to one or more respective current values of a current signal injected in the receptor apparatus through the analog current output;
• and
• Performing a determination of a type of an analog electrical output signal to be output by the output interface, based on the one or more measured voltages.

A computer program product comprising computer program code tangibly embodied in a computer readable medium, said computer program code comprising instructions which, when executed by one or more processors, cause the one or more processors to perform an operation for configuring a source apparatus adapted for processing an analog electrical output signal output to a receptor apparatus, the source apparatus being electrically coupled to the receptor apparatus through an output interface comprising a first and second output signal terminals of the source apparatus;

• the operation comprising:
• Configuring the output interface of the source apparatus to be an analog current output;
• Obtaining one or more measured voltages respectively corresponding to one or more respective current values of a current signal injected in the receptor apparatus through the analog current output;
• and
• Performing a determination of a type of an analog electrical output signal to be output by the output interface, based on the one or more measured voltages.
