All Implemented Interfaces:
java.io.Serializable, java.rmi.Remote, ScheduleOwner, Device, DeviceServiceIF, Instrument

public class PowerSwitch
extends PolledInstrumentService
implements Instrument

Basic power switching, no instrument communications. Each sample cycle, turns instrument on, sleeps for instrumentStartDelay milliseconds, (allowing other processes to run) and then turns power off.
