General Details

Introduction of Serial Ethernet converter

Serial ethernet converter USR-N510, which can realize bidirectional transparent transmission between RS232/RS485/RS422 and Ethernet.

Through simple settings via webpage or setup software can assign working details, realize serial data and TCP/IP data package transparent transmission by serial ethernet converter
USR-N510 is based on ARM processor and it is internally integrated with TCP/IP protocol. User can easily realize embedded device networking.
