<p>PURPOSE:To eliminate misinput on operation keys and improve the reliability of data by automatically sending the discrimination code set for the machine to a control terminal device side when a header is inputted. CONSTITUTION:An electrically rewritable nonvolatile memory(E<2>PROM) 12 is connected to a CPU 7 through a memory interface. In this nonvolatile memory 12, the discrimination code (machine number, etc.) of the agricultural machine is recorded. The data gathering device 20 is mounted on a communication interface unit and the power-ON switch is turned ON, so that a communication between the data gathering device 20 and a controller 1 is started. A control program on a ROM card 28 confirms whether or not the kind and type of the actual agricultural machine are matched first. If there is abnormality in the communication, an error message is displayed and when not, it is confirmed whether or not there is a machine number as the discrimination code. Once the machine number is set, a header input screen appears again and the header is inputted with input keys.</p> |
