PURPOSE:To operate a switching device automatically by a signal from a testing device side without bringing the switching device under the control of an information processor, by providing plural connection points, etc., for connecting a master computer to respective testing devices selectively. CONSTITUTION:The plural connection points, etc., are provided for connecting the master computer to the respective testing devices selectively. For example, a reset switch S3 is pressed to reset a counter circuit 10; and the connection point 16 of a switching driving part 15 is connected to an initial point and the information processor 1 is connected to the testing device 5 of #1. Then, a start switch S1 is pressed and a start signal 18 is generated by a start signal generating circuit 12 to start the testing device 5 of #1; and a receiver circuit 4 outputs a request to control to the information processor 1 through a communication circuit 8. Then, the information processor 1 transmits a control signal to the testing device 5 of #1 through the communication circuit 8 and the testing device of #1 tests an objective equipment 7. |
