A data arrangement calculating system including a master unit and a plurality of slave units connected with said master unit. Optical couplings on the connection transmit invisible energy to identify the instrument and are proximate on the first and second parts. In addition, the present invention relates to a novel intermediate compound useful for the synthesis of this sulfonic acid derivative of hydroxamic acid. A plurality of bumps 18 have been connected one-to-one with the metal layers 24. The processing module couples the receiving module and generates the control to set the parameters according the first output signal and the second output signal.
