When both SW1 and SW2 are open, the control circuit 280 may define an open circuit.
When SW1 is closed and SW2 is open, the interrogation signal *may undergo half-wave rectification* in a first direction (e.g., positive half of interrogation signal blocked).
When SW1 is open and SW2 is closed, the interrogation signal may undergo half-wave rectification in a second direction (e.g., negative half of interrogation signal blocked).
When both SW1 and SW2 are closed, no rectification may occur.
Accordingly, based on the different characteristics of the interrogation signal corresponding to the different states of SW1 and SW2, the state or configuration of the control circuit 280 may be discerned by the generator 102 based on a voltage signal appearing across the inputs of the control circuit 280 (e.g., as measured by an ADC of the signal conditioning circuit 202).
