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.
Benefits:
1. Support 2-channel RS232/485 to 2-channel 10/100M Ethernet (can be cascaded).
2. Support Modbus RTU/ASCII and Modbus TCP conversion
3. Support DC9~60V non-polar input, dual power supply redundancy design, 6KV lightning protection
4. Modbus configuration-free pre-read, single serial port supports 256 Modbus RTU instructions, and the number of connections is synchronously extended to other transparent transmission modes
5. High-strength aluminum alloy shell, IP40 protection level, fanless shell heat dissipation, stable operation in harsh industrial environment of -40°C~+85°C
