The expander device includes a processor/controller configured to receive a master data stream from an initiator device and to transmit a returning master data stream to the initiator device. The expander device includes a plurality of target master ports coupled to the processor/controller and configured to transmit split data streams to corresponding target devices coupled thereto and to receive returning split data streams from the target devices. The processor/controller splits the master data stream, based on its data, into a plurality of split data streams, and directs the split data streams to the target master ports based on the data in the split data streams. The processor/controller also assembles a plurality of returning split data streams into the returning master data stream and transmits the returning master data stream to the initiator device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Serial input output (SIO) port expansion apparatus and method","description":"An expander device and method for transmitting serial input/output (SIO) data between an initiator device and a plurality of target devices.
