Abstract
A multi-tier, master-slave control network having multiple buses comprises a master node and a plurality of slave nodes operating over each of the multiple buses. Each master node comprises a downlink transceiver, and each slave node comprises an uplink transceiver. All of the nodes in the control network are connected in a continuous loop configuration with each segment of the loop comprising a cable connector of either a first type (feed thru) or a second type (crossover). Each cable connector comprises a pair of signal wires for each bus. The type of cable connector between any two adjacent nodes in the loop is related according to which of the uplink or downlink transceiver should be connected to which bus.
