Feature

●RS485 to WIFI/Ethernet serial server supports RS485 to WIFI, RS485 to Ethernet, Ethernet to WIFI, etc. supports TCP Server / TCP Client / UDP Server / UDP Client
●Serial command mode, the user sends data to the server according to the protocol, send data to different servers without restarting
●Support HTTPD Client Mode, after the user has set the HTTP header through AT commands or web page, the module can send data to the HTTP server, or obtain data from the HTTP server
●Support MQTT function, support Modbus TCP and Modbus RTU interconversion mode
●Industrial rail-mount support, easy to install, compact size, cost-effective. Power supply is not included, it is recommended to use a 12V Industrial DIN-Rail Power Supply


Description

Overview
This is a RS485 device data acquisitor / IoT gateway designed for industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to HTTPD Client, etc. With RS485, WIFI and Ethernet ports, the module can realize functions such as serial to WIFI, serial to Ethernet, Ethernet to WIFI and so on. Using screw terminals for power input, it supports 5~36V wide range power supply. Rail-mount V0 flame-retardant case design, small in size, easy to install.
