Overview
Introduction
Yacer MVB-TCMS Train MVB Bus Converter integrates one MVB interface, two Ethernet interfaces, and supports expansion interfaces such as RS-232/422/485 and CAN. It enables protocol conversion between MVB, Ethernet, serial ports, and CAN bus, and optionally supports the TRDP protocol.
Designed with industrial-grade wide temperature tolerance and comprehensive isolation protection, the converter features a compact structure, making it ideal for train communication network applications.
Applications
Protocol conversion between MVB and Ethernet interface
Port conversion between MVB and serial port
Interface conversion between serial port and Ethernet interface
Protocol conversion between CAN and Ethernet interface
Protocol conversion between TRDP and UDP
Protocol conversion between TRDP and serial port
