| Abstract: | The process of the performance test of tillage machinery was using a single chip computer to collect data and a kind of special coder to carry data through high frequency carrier to transmit coding signals to the ground receiver and then through a corresponding decoder, 4 bits of parallel data could be immediately obtained. From the standard 25 pin connector of printer, PC directly took those data. |
