Multi Communication Modes---Supports TCP Server / TCP Client / UDP Mode / UDP Multicast

RS485 TO ETH (B)

TCP Server will be listening configured ports and waiting for TCP Client connections, data from the serial device will be transferred via TCP Server to every connected clients.

TCP Client will try establishing TCP connection with configured IP to achieve bi-directional transparent transfer between the server and serial device, and keeps retrying if failed

RS485 TO ETH (B)

UDP Server will automatically send the received data to the target of previous communication. suitable for multi network devices communicating with the UDP Server

UDP Client will communicate with specific IP and port no. only, thus improving the data transfer accuracy

RS485 TO ETH (B)

When used as MQTT gateway, the devices can upload serial data to MQTT server by MQTT protocol through transparent transmission, supported servers including Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet, etc. The acquired Modbus RTU or non-standard serial data can be parsed into JSON format and packaged into MQTTdata packet for uploading.

When used as JSON data acquisition gateway, the devices can be connected to data acquisition instruments through RS485 connection, then acquire data automatically, convert the data into JSON format, and finally post it to server. The acquired data supports Modbus RTU 645 instrument 97 version, 645 instrument 07 version, as well as sorts of non-standard RS485 protocols. The uploaded data format can be configured via host, and the JSON upload protocol can be MQTT protocol, HTTP POST protocol, HTTP GET protocol, and so on.
