Serial to Ethernet Converter USR-N668 Introduction of 8-port RS232/422/485 Serial Device Servers

Serial to Ethernet Converter USR-N668 is a 8-port RS232/422/485 serial device servers.

Features of USR-N668

  • 8-port RS-232/422/485 serial device servers.
  • Power supply accepts wide voltage input range AC 85-265V.
  • Support TCP server/client, UDP server/client, https client, Virtual COM.
  • Support Modbus RTU to Modbus TCP.
  • Support flow control CTS/RTS, XON/XOFF.
  • Support 8 software selectable RS-232, RS-485/422 RJ45 serial port to 1 10/100Base-T(X) self-adaptive Ethernet interface, rack-mount.
  • Configuration via Web Server page, AT commands, and Windows Utility.

Work mode

  • TCP Server
    • Serial server devices USR-N668 listen on the setting port and wait for a TCP client connection.
    • The data which the serial ports sent out transparently transmit to all connected client via serial device USR-N668.
  • TCP Client
    • Serial device servers USR-N668 initiate a TCP lint to the set IP address.
    • If the connection fails, N668 will keep trying to reconnect until it succeeds.
    • Once the link is successful, the data will be transparently transmitted between PC and serial device in bi-directional.
  • UDP Mode
    • Serial server devices USR-N668 sent the data to designated IP /Port. If the connection fails, USR-N668 will keep trying to reconnect until it succeeds.
    • USR-N668 listen the port and forward all data received to serial device.
  • https D Client

    • Support serial data transmitted to designed server in https D way.

Basic Function

  • ARM9 Solution.
    • 64MB built-in RAM, 16MB Flash, high speed
  • Rack-type serial device servers.
    • Shell size: 482*185*45mm
  • Serial port switching among RS232/RS485/RS422
    • New and industrial design which saves the port space of device, prevent from ash and collision and promote the safety while operating.
  • Interfaces of serial device servers USR-N668
  • 8 serial ports
  • Hardware protection
    • EFT: Electrical fast pulse train: Ensure that the equipment hardware is not damaged when the instantaneous large current (such as lightning strike, power switch, etc.) occurs in the circuit
    • Electrostatic protection ESD :Prevent electrostatic damage to equipment ( ex body static electricity, dust static electricity, such as lightning strike, power switch, etc.) electric power application environmental arc)
    • Watchdog
    • Hardware watchdog design, never crash in 24 hours

Special function

  • VPN+ Diagnosis of network + Timing task +DDNS+ Modbus TCP to RTU.
  • Remote monitoring can check the running status of field equipment.
