Product Overview

The 4G serial port servers HF2421&HF2421G provide a product for protocol conversion between RS232/RS485/RS422, Wi Fi/Ethernet, and 3G/4G, meeting the solution for industrial product serial network data transmission channels. This product integrates rich hardware interfaces such as 4G/3G, Wi Fi, Ethernet, high-speed serial ports, RS232, RS485, RS422, etc., and is based on the ECos operating system. The product includes a web page and TCP/IP protocol stack, which can easily achieve remote data collection and monitoring. The hardware interface meets the national standard requirements, and ESD supports air discharge ± 15KV and contact discharge ± 8KV. The HF2421&HF2421G serial servers adopt highly integrated hardware and software platforms, which have been optimized for industrial applications, smart grids, and personal health and medical applications. Only adding one product can meet the needs of equipment data monitoring and transmission.
