Products Content:

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 But that doesn't mean your existing equipment and software investment is out of date due to a lack of Ethernet or TCP/IP connectivity.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 3onedata Express, devices such as CNCs, milling machines, card readers, PLCs, switching machines, sensors, and UPS systems will become powerful tools with network connectivity.
3onedata Express supports Windows 95/98/Me, Windows NT, and Windows 2000/XP/2003 native COM drivers, meaning that your existing COM port based application software will be completely compatible.,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, Entrance control, security/attendance management Manufacturing automation, Telecom and fiber optic network management ,Industrial control and process control, Hospital/Laboratory automation, Remote image transmission
