PURPOSE:To offer a connecting route confirming system where the system is confirmed more accurately and troubleshooted easily by shifting stored information respectively in a transmission register and a reception register to use not only data information but also control information as an object of return. CONSTITUTION:The control information alpha and the data information beta generated in a controller 11 are stored in the transmission shift register 34. A controller 35 views the information alpha and superimposes the information beta on a connecting route toward a designated device 12-1 to be controlled. The transmitted information beta is shifted in the shift register 42. A controller 35 in the device 11 shifts the information alpha in the shift register 34. Further, the information alpha is transmitted similarly toward an opposite shift register 42. The controller 11 views not only the information beta but also the information alpha, compares them with the original information alpha and beta generated in itself and when there are coincident respectively, it is confirmed that the connecting route is set correctly. |
