HF2211
IOT Device Product
The HF2211 provides RS232/RS485/RS422 interface to Ethernet/Wi-Fi connectivity to web enable any device. The HF2211 integrate TCP/IP controller, memory, 10/100M Ethernet transceiver, highspeed serial port and integrates a fully developed TCP/IP network stack and ECos OS. The HF2211 also includes an embedded web server used to remotely configure, monitor, or troubleshoot the attached device.
The HF2211 using highly integrated hardware and software platform. It has been optimized for all kinds of applications in the industrial control, smart grid, personal medical application and remote control that have lower data rates, and transmit or receive data on an infrequent basis.
The HF2211 integrates all serial to Ethernet functionality with 95 x 65 x 25mm size.
