Overview

Industrial serial server, RS485 to RJ45 Ethernet, TCP/IP to serial, rail-mount support

Features :

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 JSON etc. The module features RS485 and Ethernet ports, uses screw terminals for power input, supports 9~24V wide range power supply. Rail-mount flame-retardant case design, small in size, easy to install. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT and intelligent instrument monitoring.

MQTT/JSON to Modbus  :
When used as MQTT gateway, the devices can upload serial data to MQTT server by MQTT protocol through transparent transmission, supported servers including Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet etc. The acquired Modbus RTU or non-standard serial data can be parsed into JSON format and packaged into MQTT data packet for uploading.


When used as JSON data acquisition gateway, the devices can be connected to data acquisition instruments through RS485 connection, then acquire data automatically, convert the data into JSON format, and finally post it to server. The acquired data supports Modbus RTU 645 instrument 97 version, 645 instrument 07 version as well as sorts of non-standard RS485 protocols. The uploaded data format can be configured via host, and the JSON upload protocol can be MQTT protocol, HTTP POST protocol, HTTP GET protocol and so on.
