• 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- :easy to combine multi rail-ed 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..
