Double Serial Device RS232/RS485/RS422 to Ethernet Server

Serial Device Server Introduction

USR-N520 is a double serial device server,which can realize transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface.The device has unique functions such as network printing,Modbus multi-host polling and watchdog mechanism. USR-N520 is based on ARM processor and it is internally integrated with TCP/IP protocol.User can easily realize embedded device networking.
