RS232/485 TO WIFI POE ETH (B) User Manual

3. OVERVIEW

3.1 INTRODUCTION

The RS232/485 TO WIFI POE ETH (B) serial server supports UART-to-Wi-Fi, allowing you to
convert a serial port (RS232 or RS485) into a TCP/IP network port. This enables bidirectional
transparent data transmission between the serial interface (RS232 or RS485) and Wi-Fi. This enables
serial devices to immediately have TCP/IP network interface functions, connect to the network for
data communication, greatly expanding the communication distance of serial devices, as shown in the
following figure:
Users do not need to worry about specific details. The module completes protocol conversion
internally, and can achieve bidirectional data transmission between the serial port and WIFI through
simple settings.
