Serial RS485 to TCP/IP Ethernet Server

Introduction

This is a serial RS485 to Ethernet server,used for data transparent transmission.USR-TCP232-304 is a low-cost serial device server,whose function is to realize bidirectional transparent transmission between RS485 and Ethernet.USR-TCP232-304 is internally integrated with TCP/IP protocol.User can apply it to device networking communication.
