Description
Description
2-channel RS485 to Ethernet, Modbus/MQTT/JSON support, rail mount metal housing
This is a 2 channel RS485 device data acquirer/IoT gateway designed for industrial environment. Dual RS485 can work simultaneously without interfering with each other. It combines multiple functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON and network switch. The module has two RS485 ports and two Ethernet ports (PoE function optional), uses a DC port (outer diameter: 5.5mm, inner diameter: 2.1mm) and a screw terminal for power supply. The enclosure with rail mounting bracket is small in size, easy to install and cost-effective. It is suitable for applications such as data acquisition, IoT gateway, IoT safety and security, and intelligent instrument monitoring...

More Flexible Conversion Between Different Protocols
When used as an MQTT gateway, devices can upload serial data to the MQTT server via 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 the MQTTdata packet for download.
When used as a JSON data acquisition gateway, the devices can be connected to data acquisition instruments via RS485 connection, then acquire data automatically, convert the data to JSON format and finally publish it to the server. The acquired data supports Modbus RTU 645 instrument version 97, 645 instrument version 07, and non-standard RS485 protocol types. The format of uploaded data can be configured through the host, and the JSON upload protocol can be MQTT protocol, HTTP POST protocol, HTTP GET protocol, etc.
Different network devices will be identified and responded to respectively,
No More Crosstalk Problem When Communicating With Multiple Network Devices
Easy for Cloud Communication and Device Identification
Obtain Network Time Information for Serial Output or Data Download
Supports Web Browser Configuration, Obtaining Dynamic IP Address via DHCP,
