Product Description

Introduction

This is a serial RS232/RS485/RS422 to Ethernet server, used for data transparent transmission.USR-N540,a four serial device server,can realize transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface.

USR-N540,based on ARM procesor,is of low power,rapid speed and high stability.And N540 is internally integrated with TCP/IP protocol.User can easily realize embedded device networking.

Features

Support TCP Server, TCP Client, UDP, UDP Server, HTTPD Client,websocket, various of ethernet protocols.

Serial port highest baud rate from 600bps ~ 230.4Kbps.

Supply the protocol for VIP customers

Provide PC TCP/IP SOCKET programming example, VB, C++, Delphi, Android, IOS.

Can also set via UDP broadcast, provide the set up protocol.

Reload button, a key restore default Settings.

RJ45 status indicator light, RJ45 interface built-in isolation transformer, 2 KV isolation.

The global unique MAC address bought from IEEE, the user can define MAC address

Support upgrade firmware via network.

Support remote IP and domain name at the same time

Support up to 8 link from client when act as TCP Server, same data will be send to all client.

Can modify http server port from default port 80 for module built-in http server.

Support Keepalive, detect a dead link quickly and make sure the connection more stable.
