Industrial serial port server series products, mainly realize the data transmission between Ethernet and serial port (RS-232/RS-485/RS-422), it integrates the TCP/IP protocol stack, RS-232/RS-485/RS-422 devices that are not connected to the Internet can also be easily, flexibly and quickly connected to Ethernet. The series of products use high-performance ARM chip to ensure stable data transmission; Support a variety of working modes to meet different application requirements; Excellent anti-interference performance, suitable for harsh industrial environments.
● Support 8-way RS232/485 to 2-way 10/100M Ethernet (can be cascaded)
● Support Modbus RTU/ASCII to Modbus TCP
● Support TCP Server/TCP Client/UDP/UDP multicast/Pari Connection/virtual serial port and other work modes
● Support MQTT on the cloud (Ali MQTT, China Mobile OneNet, Huawei Cloud MQTT, private cloud, etc.), HTTPD, WebSocket, etc
● Support data forwarding function between serial ports
● Strong terminal wiring, -40℃~85℃ wide temperature, EMC level 4 protection, standard 1U rack mounting
