Abstract
System and method for encoding status signals in DC voltage levels is provided. The value of a status indicator received on status signals are encoded as a series of pulses, and the voltage level from a power source, such as a power supply or a rechargeable battery, is modulated in accordance with the series of pulses. In an embodiment, the voltage level from the power source is varied between two levels, both of which are acceptable power levels. The drops in the voltage levels represent the value of the status indicator. On the receiving end, the power signal is translated into a logical voltage level and converted to a digital value. The digital value is decoded into the status indicator.
