<p>The method for connecting peripheral unit, which are remotely powered from a central unit by a transmission link, to an information processing system, begins by connecting the selected peripheral device to the transmission link with the remote power supply down. Later a testing voltage is applied, which is lower than the actual operating remote powering voltage of the device to be connected to the terminal, on the side of the center. The connection status of the peripheral terminals of the transmission link is evaluated by measuring the charge quantity, which runs into the transmission link from the center. In the second step when determining the correct connection status of the remote powering transmission link, the remote powering voltage is increased to the standard operation level.</p> |
