Abstract: There are two differences in the MVB bus physical layer. One is the waveform difference between ESD+ and EMD, and the other is the difference between single-channel bus line and A/B redundant bus line. The waveform difference will lead to the bus connectivity problems. The difference between the single-channel bus and A/B redundant bus will cause B bus line failure to reduce the reliability of the whole communication system. The paper introduces the design of MVB bus gateway based on the analysis of the two differences. The test result proves that the gateway has high efifciency and reliability.
