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 4-way RS485 to 2-way 10/100M Ethernet (can be cascaded)
● Supports Modbus RTU/ASCII to Modbus TCP
● Supports DC9~60V non-polarized input, dual power supply redundancy design, 4kV surge protection
● Modbus configuration-free pre-reading, single serial port supports 256 Modbus RTU commands, the number of connections synchronized expansion to other transmission modes
● Firm terminal wiring, -40℃~85℃ wide temperature, DIN-rail mounting
