Ready to Shipin Stock Fast Dispatchusr-N520 IP Serial Port Server, Serial Ethernet Server RS232 RS485 RS422 to TCP IP Converter Support Modbus Multi-Host Pollin

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.
