waveshare Ethernet Industrial Serial Server RS485 to RJ45 Ethernet Module, TCP/IP to Serial, Support Rail-Mount/Modbus Gateway, TCP Server/TCP Client/UDP Mode/UDP Multicast Multi Communication Modes

This is an RS485 device data acquisitor / IoT gateway designed for the industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc. Bi-directional transparent data transmission between RS485 and Ethernet.;
Support Rail-mount: easy to combine multi rail-mounted serial server together, more freely.
Support Modbus gateway: suitable for Modbus gridding upgrade, can be used with 3D configuration software.
Support NTP protocol: getting network time info for serial output or data upload.;
Multi communication modes: supports TCP server / TCP client / UDP mode / UDP multicast.
Multi configuration methods: supports Web browser configuration, obtaining dynamic IP via DHCP, DNS protocol connected domain server address.
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;
User-defined heartbeat/registration packet: easy for cloud communication and device identification.
