Features at a glance

This is a 2-ch RS485 device data acquisitor / IoT gateway designed for the industrial environment. Dual RS485 can work simultaneously without interfering with each other. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, and network switch. The module features dual RS485 and dual Ethernet ports (PoE function optional), uses a DC port (outer diameter: 5.5mm, inner diameter: 2.1mm) and screw terminal for power input. The case with rail-mount support, is small in size, easy to install, and cost-effective. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring...

MQTT/JSON to Modbus

More flexible conversion between different protocols

2-CH-RS485-TO-ETH-B-details-19.jpg

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.
