Abstract
A system for accomplishing bi-directional digital audio data and control communications. There is a host end that includes a host transceiver, a host digital signal processor that outputs a master clock signal and audio data, and a source of low-voltage power for the host components. There are a number of remote nodes connected together serially. Each remote node includes a transceiver and a low-voltage power supply that provides power to the other remote node components. A shielded two-wire communication network connects the host node to one of the remote nodes, and connects each remote node to either one or two other remote nodes in a daisy-chain configuration. The host end is enabled to transmit and receive over the communication network digital audio data and digital control signals. The remote nodes are each enabled to receive over the communication network digital audio data and digital control signals, and are each enabled to transmit over the communication network digital control signals. The source of low-voltage power at the host end is coupled to the communication network. The remote power supplies each have an input coupled to the communication network to derive the pow…
