 Unlike the more common X10 protocol which uses a signal imposed upon the AC power line, C-Bus uses a dedicated low-voltage cable or two-way wireless network to carry command and control signals.This improves the reliability of command transmission and makes C-Bus far more suitable for large, commercial applications than X10.The C-Bus System can be used to control lighting and other electrical systems and products automatically or via remote control and can also be interfaced to a home security system, AV products or other electrical items.
