To my understanding APC BACK-UPS CS & RS uses Simple signaling meaning it cannot receive and store a delay time. Therefore even if the OS has succesfully shutdown the UPS will continue to supply output (assuming long period power failure) untill batteries had totally depleted. But in the event that the power is restored before batteries are depleted then the PC would have to be switched on manually - correct me if i'm wrong.
so my question goes:
1. When power is restored after low battery shutdown state will the UPS power on automaticaly and supply output to my loads ?
2. The term Simple Signaling refers to the UPS USB/Serial interface communication mode or because PowerChute Personal Edition supports only simple signaling ?
