a schedule to determine whether the connector is properly mounted and connected between a selected outlet and a selected inlet the identifiers include rfids and barcodes the identifiers are preferably angularly spaced around the outlets inlets and the couplers of the connector the identifier may be affixed by snap rings mounting barcode labels or rfid buttons application_number US 201414513391 A description with reference to the drawings wherein like numerals represent like parts throughout the several figures a connection line protection system has numerous applications including the disclosed applications wherein the connection line protection system automatically determines whether a line connection between a port of a manifold of ports and a selected second port for an outlet line is correctly connected or a hose is correctly connected between a fuel tank truck reservoir and the proper underground storage tank such as employed in fuel dispensing stations the connection line protection system preferably employs handheld scanners which have rf communication capability and read barcodes or rfid tags to determine whether or not the connections are correct the connection line protection system may be employed to ensure proper connections between manifold line ports and fill ports as shown in fig1 and 2 a representative distribution manifold 100 which shows quick connect storage tank manifold ports 101 103 and quick connect filler line manifold ports 105 107 as many as 100 manifold ports may be mounted to a distribution panel 100 manifold ports 101 are connected to storage tank number one 102 manifold ports 103 are connected to storage tank number three 104 manifold ports 117 are connected to storage tank number five 114 and manifold ports 105 are connected to fill line number one 106 manifold ports 107 are connected to.
