2-Ch RS485 to RJ45 Ethernet Serial Server, Dual channels RS485 independent operation, Dual Common Ethernet Ports 

This is an RS232/485/422 device data acquisitor/IoT gateway designed for an industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS232/485/422 to JSON, etc. Adopting RS232/485/422 and Ethernet interface with PoE function, it can be connected with screw terminals for power input by the power port (outer diameter: 5.5mm, inner diameter: 2.1mm). The rail-type case design, is small in size, easy to install, and cost-effective. It is very suitable for collecting the data of RS232/485/422 and sensors in the industrial field, including local network collection or uploading to the data that the cloud server autonomously collects and sends.
