Description
USR-N540 is an Industrial Serial to Ethernet Converter to realize bi-directional transparent transmission between RS232/RS485/RS422 and network with function of modbus gateway.
- 4 serial ports, each one can select RS232/ RS485/RS422
- Hardware Watchdog, keep to work stable
- Modbus RTU -TCP, Customized webpage, websocket
- Serial ports can work simultaneously
