Rail-mount RS485 serial server
RS485 TO ETH (B)
Common Ethernet port
RS485 TO POE ETH (B)
PoE Ethernet port + Electrical isolation
These two versions are the same in software functions, while RS485 TO POE ETH (B) is the hardware upgrade version, support PoE Ethernet port power supply, with power and signal isolation protection, which is safer for industrial applications.
This is an RS485 device data acquisitor / IoT gateway designed for the 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 port(POE function is optional), uses screw terminals for power input. Rail-mount 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...

Bi-Directional Transparent Data Transmission Between RS485 And Ethernet
Easy To Combine Multi Rail-Mounted Serial Server Together, More Freely
Suitable For Modbus Gridding Upgrade, Can Be Used With 3D Configuration Software
Supports TCP Server / TCP Client / UDP Mode / UDP Multicast
More Flexible Conversion Between Different Protocols
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.
