CONNECTION CONFIRMING SYSTEM FOR CONNECTOR

摘要

PURPOSE:To confirm misconnecton of a connector easily at a connection requesting device, by returning a device set number selected with the connector to the device of the connection request. CONSTITUTION:A device corresponding section C1 of the 1st group decodes the set number of a device Bm with a decoder 3 and outputs the connection request to the 2nd group device corresponding section Dm being objective through a selector 4. The section Dm selects the connection request. It is assumed that a competitive control circuit 5 selects the connection request from the device A1 of the 1st group. A device number generating circuit 6 generates the device number of the device Bm of the 2nd group corresponded and transmits the number to the device A1 of the 1st group. The device A1 of the 1st group checks the propriety of the connection and when normal, the data transfer with the device Bm of the 2nd group successively, and if in failure, the failure processing is performed.
