Overview
Introduction
Yacer HDLC-TCMS Synchronous Serial Converter is specifically designed for train network communication. It is equipped with 2 100Mbps Ethernet ports, 2 RS-485 sync/async serial ports, and 2 expansion interfaces (optional RS-232/422/485 or CAN interfaces). The device supports protocol conversion between synchronous HDLC, asynchronous UART, CAN bus, and Ethernet.
Featuring an industrial-grade wide-temperature design and robust isolation protection mechanisms, the converter offers a compact structure, stable and reliable operation, meeting the demands of long-term use in harsh rail transit environments.
