Abstract: A digital communication network including several receivers and a communication method for the digital communication network are provided. Each of the receivers includes a first port and a second port. The first port of the first receiver is coupled to the microcontroller. The first port of each of the receivers except the first receiver is coupled to the second port of the previous receiver. Each receiver further includes a chain register. The chain registers of the receivers are mutually connected through the first ports and the second ports, forming a virtual global queue. By utilizing the characteristics of the virtual global queue, the system and the method achieve bi-directional, single-wire, serial communication without the encumbrance of assigning addresses or identification codes to the receivers.
