4 Serial Port RS232/RS485/RS422 to Ethernet Converter

USR-N540, a four serial device server, can realize transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface. it is based on ARM processor,low power, rapid speed and high stability. And N540 is internally integrated with TCP/IP protocol. User can easily realize embedded device networking.
