METHOD AND APPARATUS FOR DATA COMMUNICATION BETWEEN PHYSICALLY SEPARATED NETWORKS

摘要

PURPOSE: A data communication method and an apparatus thereof are provided to offer data communication between an internal network and an external network. CONSTITUTION: A first communication repeater(30) receives communication data from one or more devices connected to a first network according to a communication protocol of the first network. The first communication repeater transmits the communication data to a second communication repeater(80) according to a communication protocol in a serial bus section. The second communication repeater receives the communication data according to the communication protocol of the serial bus section. The second communication repeater transmits the communication data to one or more devices connected to the second network according to the communication protocol of the second network.
