[USR-N520] 2 -Ports Ethernet to Serial converter with RS232/RS485/RS422 port, modbus gateway

Introduction of 2 ports Serial Device Servers

USR-N520, a four serial device server, can realize transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface. USR-N520, based on ARM processor, is of low power, rapid speed and high stability. And N540 is internally integrated with TCP/IP protocol.

• Cortex-M4 kernel, industrial working temperature range(-40~85C), elaborate optimization TCPIP protocol stack, stable and reliable.
• selectable RS232/RS485/RS422 port, Different port can be used together, work independently, distinguish the connected serial port via port number.
• Auto-MIDX function, discretionarily connect cross-over or direct network cable, automatic switching.
• Support TCP Server, TCP Client, UDP, UDP Server, HTTPD Client,websocket, various of ethernet protocols.
• Support virtual serial port, provide corresponding software.
• Serial port highest baud rate from 600bps ~ 230.4Kbps.
• wide voltage input, more applications.
• Support DHCP, automatically access IP, can inquire the facility within network through the setup software.
• Supply the protocol for VIP customers
• Provide PC TCP/IP SOCKET programming example, VB, C++, Delphi, Android, IOS.
• A built-in web page, also parameter setting via web, can customize web pages for users.
• 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 (please state when you make order).
• 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.

• Industrial data transmission, industrial automation
• security and protection monitoring, public security
• Smart home, power control, environmental monitoring, intelligent agriculture
• Door check on work attendance system, POS system, rice selling system
• Building automation system, power monitoring, self-service banking system, telecom machine room monitoring
