1. A system configured to establish two-way communication using a resistance level communication protocol, the system comprising:
a generator; and
an electrosurgical device comprising:
an electrical connector configured to receive a treatment signal and a continuous signal from the generator;
an AC-DC converter configured to convert the continuous signal to a DC signal;
a processor configured to receive the DC signal; and
a resistor connected to the processor and configured to vary a current of power used by the processor over time;
wherein the generator is configured to interpret variances in the current as data and provide an acknowledgement to the electrosurgical device using frequency shift keying (FSK).
