NPort 5150

1-port RS-232/422/485 serial device servers

Product Features

  • Small size for easy installation
  • Real COM/TTY drivers for Windows and Linux
  • Standard TCP/IP interface and versatile operation modes
  • Easy-to-use Windows utility for configuring multiple device servers
  • SNMP MIB-II for network management
  • Configure by Telnet, web browser, or Windows utility
  • Adjustable pull high/low resistor for RS-485 ports

NPort 5150 device server (RS-232 / 422/ 485  to ethernet converters) is designed to make your serial devices network-ready in an instant. The small size of the servers makes it ideal for connecting devices having serial ports to devices  as card readers and payment terminals (which have RS-232 ports) or to PLC , Energy Meters (which have RS-485 Ports) , to an IP-based Ethernet LAN. Use the NPort 5150  device servers to give your PC software direct access to serial devices from anywhere on the network. Using Serial to ethernet converters to connect legacy serial devices to Ethernet is a convenient way to bring devices  online.  Users expect such device servers to be cost-effective and to provide a broad selection of useful functions. With its full support of Microsoft and Linux operating systems, the NPort 5150  provides the best choice for RS-232 / RS-422 / RS- 485 – to – Ethernet conversions. This model has combined Ports (RS-232 / RS-422 / RS-485 Ports), whereas we have individual RS-232 to Ethernet Device Server – Nport 5110 & RS-422 / RS-485 to Ethernet Device Server – Nport 5130.
