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 to Ethernet
● 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 and so on.
● Support data forwarding function between serial ports
● Wide temperature range of 40℃~85℃, wide voltage range of 9~36V, EMC level 4 protection
