BATTERY DISPLAY UNIT (FEASIBILITY MODEL).

The report deals with the design and fabrication of a laboratory constructed breadboard model Battery Display Unit BDU. A short history discussing the requirements and a past attempt to produce a display unit similar to the BDU is included. The bdu system design concept permits it to receive and display data at speeds approaching that of the logic decoding circuits. Information reception at rates well in excess of those required is easily obtainable. The operating principles of the electro-magnetic indicators used in the BDU are described. These principles offer important operating advantages with respect to the BDU application. General BDU operation theory and detailed logic circuit design information are included. Excellent test results were obtained when operating the BDU at the required 300 characterssecond input data rate. Excellent results were also observed when operating the BDU at lower data rates. This report is concluded by comparing the operating characteristics of the BDU with that of the existing FADU model. Recommendations are made concerning further improvements and uses of the BDU. Character coding used in the BDU is described. Author
