Overview
Introduction
Yacer HDLC-UDP Embedded Synchronous Communication Module provides 1 x 100M Ethernet PHY interface, 2 x isolated RS-485/422 sync/async serial ports, and 1 x CMOS/TTL sync/async serial port. It supports NRZI, DBPL, Manchester, and Differential Manchester encoding formats, enabling protocol conversion between HDLC and UDP or UART.
With a compact size of 46.5 x 48mm and 2.54mm pin header interface, it operates on +5V power supply with low power consumption. Designed for industrial-grade wide temperature range, it is ideal for embedded applications.
