RS232/422/485 Serial to Ethernet Converter (POE)

This is a RS232/422/485 data acquirer/IoT gateway designed for industrial environment.

It combines several functions in one:

Serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc.

The module includes RS232/422/485 and Ethernet port with PoE function, uses DC port (outer diameter: 5.5mm, inner diameter: 21mm) and screw terminals for power supply. The housing with rail mounting bracket, compact, easy to install, cost-effective. It is suitable for applications such as data acquisition, IoT gateway, IoT safety and security, and intelligent instrument monitoring.
