waveshare Industrial Isolated Rail-Mount RS232/485/422 Serial Server, RS232/485/422 to RJ45 Ethernet Module with POE, TCP/IP to Serial Converter, Modbus Gateway Support

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 with PoE function. 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 PoE Ethernet port power supply, Suitable for IEEE 802.3af PoE standard. 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 gateway--- suitable for Modbus networking upgrade, Can Be Used With specific Configuration Software. Multi communication modes--- supports TCP server / TCP client / UDP mode / UDP multicast.
MQTT/JSON to Modbus--- more flexible conversion between different protocols. Multi hosts roll-polling---support: different network devices will be identified and responsed respectively,no more crosstalk issue while communicating with multi network devices. Multi configuration methods---supports Web browser configuration, obtaining dynamic IP via DHCP,DNS protocol connected domain server address.
