A surgical system is presented including a microwave generator having a resistive identification connector with a plurality of resistive channels, each resistive channel having a plurality of resistive values. The surgical system further includes a microwave applicator having a device identifier, the microwave applicator configured to be connected to the microwave generator via a reusable cable. The surgical system also includes a digital controller configured to be connected to the resistive identification connector of the microwave generator. The device identifier of the microwave applicator is relayed to the digital controller via a resistive channel of the plurality of resistive channels of the resistive identification connector to enable the digital controller to control the microwave applicator by adjusting at least one operation of the microwave generator. The microwave generator further includes at least one digital pass-through line to allow direct communication between the microwave applicator and the digital controller.
