Abstract
A power control device which incorporates a microcontroller to control the switching of power of a plurality of outlets. A host computer communicates with the microcontroller through the computer'"'"'s keyboard interface to instruct the device to turn on or off one or more of the outlets either immediately or at one or more preset future times. An operator communicates with the microcontroller through the computer'"'"'s keyboard intercede to instruct the device to initiate a sequence of pro-programmed on/off events.
