Abstract:
1. A series-connected control system, comprising: a host device that includes a string of slave devices that are coupled in series to said host device and to each other, each of said slave devices including wherein said string of slave devices includes first and second endmost slave devices, said second transmission unit of said first endmost slave device being connected electrically between said first transmission unit of said host device and said second transmission unit of an adjacent one of said slave devices, said second transmission unit of said second endmost slave device being connected electrically between said first transmission unit of said host device and said second transmission unit of an adjacent one of said slave devices; wherein said first transmission unit of said host device initially operates in the host transmitting mode, and said second transmission units of all of said slave devices initially operate in the slave receiving mode, such that said second transmission units of all of said slave devices are able to receive the encoded control signal provided by said first processing module of said host device and transmitted by said first transmission unit; and wherein said first transmission unit of said host device operates in the host receiving mode after transmitting the encoded control signal, and said second transmission unit of a target one of said slave devices corresponding to the address code in the encoded control signal subsequently operates in the slave transmitting mode for transmitting the encoded feedback signal.
