1.  Introduction

MVB-Analyzer protocol analyzer provides MVB interface, two Ethernet interfaces and two expansion interfaces to collect and receive MVB frames, WTB frames, synchronous HDLC frames, CAN frames, and UART serial data from the vehicle bus and send them to the computer via the Ethernet interface.

With the accompanying MVB-Monitor software, MVB bus data can be analyzed and counted, and MVB master simulation can be performed to find troubleshooting and evaluate MVB bus operation.

Industrial wide temperature, complete isolation and protection, compact size, suitable for train communication network.

2.  Applications
