Product Overview

  • The HF5111 serial port server provides a solution for protocol conversion between RS232/RS485/RS422 and TCP/IP, meeting the channel requirements for industrial product serial port to Ethernet data transmission. This product integrates Ethernet hardware protocols such as MAC, TCP/IP protocol stack, memory management, 10/100M Ethernet transceiver, high-speed serial port, RS232, RS485, RS422 and other rich hardware interfaces. Based on the FreeRTOS operating system, the product includes a web page for convenient remote configuration, monitoring and debugging. The hardware interface meets the national standard requirements, and ESD supports air discharge ± 15KV and contact discharge ± 8KV.
  • The HF5111 serial server adopts a highly integrated hardware and software platform, which has been optimized for industrial applications, smart grids, personal health and medical applications. Only adding one HF5111 product can meet the needs of device data monitoring and transmission.
