ABSTRACT:
A data relay system transmits addresses from a host device sequentially to each of a plurality of data relays and for transmitting data sequentially through each of the plurality of data relays to the host device. Serial addresses are placed on the data bus by the host device and received by a Signal Conditioner in the data relay and passed through an Address Parallelizer and Address Selector. If the address is recognized by the Address Selector, then a Data Group is counted by the Data Group Counter while the Data Group is enabled. The enabling of a selected Data Group will result a selected parallel data being supplied to the Data Group Serializer which present the parallel data for serial transmission to the host device.
