★HF2211S
- Product Code: HF2211S
Product Overview
- The HF2211S serial-to-Wi-Fi server provides a solution for protocol conversion between RS485 and Wi-Fi, enabling wireless data transmission for serial devices. It integrates a TCP/IP protocol stack, memory management, a high-speed serial port, RS485, and other hardware interfaces, all based on the mbed operating system. The product includes a web interface and IOTService software, facilitating local or remote configuration, monitoring, and debugging.
- Leveraging a highly integrated hardware and software platform, the HF2211S is optimized for industrial applications, smart grids, and personal health care. Simply adding an HF2211S unit meets the needs for device data monitoring and transmission.
- The software functionality of the HF2211S is identical to that of the Elfin-EW, differing only in hardware interfaces.
