<p>PURPOSE:To enable a host to select a subject device to be disconnected it or applied from/with an automatic power supply by switching on or off the power supply designated by a power supply control command when the coincidence is secured between an address defined within the power supply control command and an address proper to its own device. CONSTITUTION:An automatic power supply control device 1 receives a power supply control command delivered from a host via a reception part 2 according to a designated circuit speed and a synchronizing system. An address comparison part 6 compares an address defined within the power supply control command and an address set at an address setting part 5. When the coincidence is obtained between both addresses, the power supply ON or OFF control is applied to a device 9 which automatically undergoes the power supply ON/OFF control by a power supply control command 7. Thus the host can discriminate a device to be controlled and the power supply ON state can be evaded to the undesired devices.</p> |
