This is an RS485 device data collector/IoT gateway specially designed for the industrial environment, which combines serial server, Modbus gateway, MQTT gateway, RS485 to JSON, and other functions. It has an RS485 interface and an Ethernet interface. It adopts the rail-type installation, which is compact and easy to install. It is very suitable for the collection of various RS485 instruments and sensors in the industrial field, including the collection of the local network or the autonomous collection of uploading to the cloud server.

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 MQTTdata 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.
