A multicast communications system that updates multicast trees in a reliable way to prevent transmitted packets from being dropped or reversed before they reach their destinations. The resulting connection across the primary and secondary selectively provides and efficient coupling of data in a multi-phase environment including step-down distribution transformers and \u201c\u0394\u201d-to-\u201cY\u201d configured circuits while maintaining isolation at the power line frequency. The connection state acquisition unit is used for acquiring the connection state between the electronic device and a remote control unit, and the remote control unit is used for remotely controlling the electronic device. The clock drift compensation system has access to this capture buffer and render buffer. The outputs of the enabled detectors is received by the multiplexer to complete the operation of the selected operating mode. Level projections extend from the clip structure to ensure that the clip structure remains level during fabrication.
