Re: Intermittent digital signal when PWMs are used

I'm betting that it is an intermittent short downstream of the DSC. The DSC's power supplies are designed to gracefully handle short circuits by shutting down their output until the short is cleared (rather than dumping large currents through it). Try wiggling each of the connected wires to see if the 5V or 6V lights blink.
