Serial to Ethernet TCP/IP 4 Serial Ports RS485 RS422 RS485 Server Modbus

Description

Introduction
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 processor,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
Cortex-M4 kernel,industrial working temperature range and TCPIP protocol stack.
Auto-MDI/MDIX,RJ45 port with 10/100Mbps
TCP Server,TCP Client,UDP Client,UDP Server and HTTPD Client work mode
Four ports can work independently at the same time
Can distinguish which serial port connects to the device via port number
Support virtual serial port and provide corresponding software USR-VCOM
Serial baud rate from 600bps to 230.4K bps
DNS and DHCP supported
Provide PC TCP/IP socket programming example such as VB,C++,Delphi,Android and IOS
