Abstract
A disclosed method for LED control for a detachable reversable power cable includes detecting, at a power source, that a first connector at a first end of the power cable is connected to the power source, triggering, at the power source, a first pulse on a first wire of the power cable that turns off a first LED switch coupled to a first LED on the first connector, disabling the first LED, and triggering, at the power source, a second pulse on a second wire of the power cable that drives a second LED on a second connector at a second end of the power cable opposite the first end, the second LED being coupled to a second LED switch that is on. The method further includes, responsive to detecting that the second connector is connected to a power sink, modifying a driver path for the second LED.
