Realize RS485 to Ethernet two-way transparent transmission function
Rail installation is more convenient
Flat design can be used for combined side by side use, higher degree of freedom 
It is suitable for Modbus network upgrade and can cooperate with 3D force control modal components
Support TCP server / TCP client / UDP mode / UDP multicast 
Multiple protocol conversion more freely
When used as an MQTT gateway, the device can use the MQTT protocol to upload serial port data to the MQTT server through transparent transmission. Supported servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet platform, etc. Support to parse the collected Modbus RTU or non-standard serial port data into JSON format, encapsulate it in MQTT data package and upload it.
When used as a JSON data collection gateway, the device can be connected to a data collection instrument via RS485, and then automatically collect data and convert it into JSON format and send it to the server. The collected data supports Modbus RTU 645 meter 97 version, 645 meter 07 version, and various non-standard RS485 protocols. The user can configure the uploaded data format through the host computer. When JSON is uploaded, it can support the MQTT protocol, HTTP POST protocol and HTTP GET protocol
It can identify data sent by different network devices and respond accordingly to prevent data misalignment.
Effectively solve the problem that the serial device responds misplaced after multiple network devices send data at the same time. 
Custom heartbeat package and registration package can facilitate communication and device identification with the cloud 
Get network time for serial port output or for protocol content upload 
Support Web browser configuration, support DHCP to obtain IP dynamically
DNS protocol connection domain name server address
