Abstract:
1. An interface apparatus cascading system, comprising: a host, comprising a first controller and a first interface port, wherein the first controller provides data transmission of a first channel and a second channel through the first interface port; a first-type interface apparatus, comprising a second controller, a second interface port, and a third interface port, wherein the second interface port is connected in series with the first interface port, the third interface port is connected with the second interface port, data of the first channel is transmitted to the second controller through the second interface port and to the third interface port through the second controller, and data of the second channel is directly transmitted to the third interface port through the second interface port, wherein the data of the second channel cannot be transmitted to the second controller; and a second-type interface apparatus, comprising a third controller, a forth interface port, and a fifth interface port, wherein the forth interface port is connected in series with the third interface port, the fifth interface port is connected in series with the forth interface port, the data of the second channel are transmitted to the third controller through the forth interface port and to the fifth interface port through the third controller, and the data of the first channel is directly transmitted to the fifth interface port through the forth interface port, wherein the data of the first channel cannot be transmitted to the third controller, wherein the first controller, the second controller, and the third controller are Thunderbolt controllers supporting dual-channel data transmission.
