An exemplary system includes a processor, a wearable device comprising a plurality of slots, and a first module including a plurality of detectors and a module control circuit. The processor is configured to successively transmit, to each slot of the plurality of slots, a command to enable a respective module located in each slot. The processor is further configured to determine, based on an acknowledgment received from the module control circuit, that the first module is enabled and located in a first slot, and to successively transmit, based on the determining that the first module is enabled and located in the first slot, a plurality of detector address identifiers. The module control circuit is configured to successively place the plurality of detectors into an enumeration mode in which each detector of the plurality of detectors is assigned a different detector address identifier of the plurality of detector address identifiers.
