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.

Feature

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
