RS232/485/422 and Ethernet Bi-directional transmission--- This 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. It realizes Bi-directional transparent data transmission between RS232/485/422 and Ethernet. ^^Three Different Interfaces--- Onboard RS232 / 485 / 422 Interfaces, Suitable For More Application Scenarios. Ethernet Port To RS232/485/422---The Ethernet port can send data to three serial ports at the same time. RS232 / 485 / 422 To Ethernet Port---Only one of the RS232, RS485, and RS422 can send data to the Ethernet port at the same time.
^^Three Methods For Power Supply---Support Screw Terminal and DC Power Port for Power Supply, DC 6~36V Wide Voltage Range Input^^Support Rail-mount---easy to combine multi rail-mounted serial server together, more freely. Support Modbus gatewa
