Introduction
 

"Everything is networked" is rapidly becoming the norm for enterprises the world over, and to keep pace with the trend of networked-based automation, devices must be networked in order to form an automatic data collection system for quality control, production monitoring, or even real-time cost management.

But that doesn't mean your existing equipment and software investment is out of date due to a lack of Ethernet or TCP/IP connectivity. With NPort Express, devices such as CNCs, milling machines, card readers, PLCs, switching machines, sensors, and UPS systems will become powerful tools with network connectivity.

NPort Express supports Windows 95/98/Me, Windows NT, and Windows 2000/XP/2003 native COM drivers and Linux real tty drivers, meaning that your existing COM port based application software will be completely compatible.

Benefits

  • Turn any serial device into a network device instantly
  • Easy integration with any serial device, such as personal identification devices, CNCs, PLCs, switches, UPS systems, and Medical/Physical/Chemical instruments
  • Preserve your investment by instantly turning serial devices into Internet devices that run on your existing software
  • Extremely low transition cost

Applications

  • Entrance control, security/attendance management
  • Manufacturing automation
  • Telecom and fiber optic network management
  • Industrial control and process control
  • Hospital/Laboratory automation
  • Remote image transmission
