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.
- 1 100 Gigabit Ethernet electrical port, 8 RS232/485/422 serial ports are optional
- Support Modbus RTU to TCP, support virtual serial port
- SupportTCP Server/TCP Client/UDP/UDP multicast/HTTPD/MQTT, etc
- Support custom subcontracting length and interval, etc
- External independent hardware watchdog design to prevent crashes
