Abstract
A communication system includes a host node and a plurality of network nodes. The host node has a processor, a non-transitory computer memory, a host receiver, and a host output select line. Each of the plurality of network nodes has an input select line, an output select line, and a tri-state transceiver. The host node and the plurality of network nodes are daisy chained such that the input select line of one of the plurality of network nodes is coupled to the output select line of the preceding node. The tri-state transceiver of each of the plurality of network nodes is activated when the input select line of that node receives a token from the output select line of the preceding node.
