The system includes a host and the interface apparatuses. In the host, a first controller provides data of a first channel and a second channel through a first interface port. Each interface apparatus has a second interface port, a second controller, a switch, and a third interface port. The second interface port serially connected to the first interface port receives data of the two channels and divides the same to be transmitted on a first transmission path and a second transmission path. The second controller processes data transmitted on the first transmission path. The switch switches data transmitted on the two transmission paths according to a control signal issued by the first controller. The third interface port is connected to the switch for outputting the switched data of the two channels. ## Claims ### Claim 1 A system for analyzing and managing data flow of interface apparatuses, comprising: a host, having a first controller and a first interface port, wherein the first controller provides data of a first channel and a second channel through the first interface port;
