Patent ID: 8817892

Claim:
A data communications system, comprising: a plurality of communication devices including: a host having a first receiver and a second receiver; and one or more clients, each said client including a transmitter coupled between a signal node and a transmitter node, said transmitter selectively transmitting a multistate signal from said signal node to said transmitter node; and a single conductor daisy-chain loop redundantly communicating each said multistate signal from each said transmitter to both said receivers, said single conductor daisy-chain loop electrically communicating each said transmitter node to said receivers; wherein said first receiver includes a first input having a first pull-up resistance coupling said first input to a first voltage, wherein said second receiver includes a second input having a second pull-up resistance coupling said second input to a second voltage node, wherein each said transmitter is configured to transmit a signal current for said multistate signal to said single conductor daisy-chain loop, said transmitter including an output coupled to said transmitter node wherein said single conductor daisy-chain loop electrically communicates each said transmitter node to said inputs.
