<p>PURPOSE:To prevent the complication of the mechanism of a device, and to improve the using efficiency of a communication port by saving the manpower for the communication port and a communication cable. CONSTITUTION:This system is equipped with computers 5a-5c, plural communication ports connected to noninterruptible power source parts 3a-3c which supply a power to the computers one to one, the communication port connected to the computer, address adding means 15 which adds an address indicating the noninterruptible power source parts connected to the plural communication ports to data, means 15 which judges the noninterruptible power source parts indicated by the address added by the address adding means and transmits the data from the communication ports connected to the judged noninterruptible power source parts, and means 15 which adds the address indicated by the noninterruptible power source parts connected to the communication ports to the data received through the communication ports connected to the plural noninterruptible power source parts and transmits the data to which the address is added from the communication port connected to the computer. Thus, the complication of the mechanism of the device can be prevented by saving the manpower for the communication port and the communication cable.</p> |
