Introduction RS232/485/422 TO POE ETH (B) is a RS232/485/422 device data acquisitor / IoT gateway designed for industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc. The module features RS232/485/422 and Ethernet port (with PoE function), uses
DC port (outer diameter: 5.5 mm, inner
diameter: 2.1 mm) and screw terminals for power input. The case with rail-mount support, small in size, easy to install, cost-effective.
