Abstract
A load control system includes a power supply, a load controller coupled to a load, and a supply controller. The load controller receives a first power having a first current level from the power supply, and uses the first power to cause a plurality of resistors to output a plurality of pre-defined codes. The supply controller receives the plurality of pre-defined codes, evaluates an output condition based on the plurality of pre-defined codes, and causes the power supply to output a second power having a second current level greater than the first level responsive to the plurality of pre-defined codes satisfying the output condition.
