NPort Express DE-211 provides a data communications solution for connecting
Windows and Linux hosts to asynchronous serial devices over a TCP/IP Ethernet.
You may connect your Windows 95/98/ME/NT/2000/XP host to a native
RS-232/422/485 serial port, or your PC-based Linux host to a real tty port, through a
TCP/IP Ethernet. With one asynchronous serial port connection on one end, and a
10 Mbps Ethernet connection on the other, NPort Express allows
virtually any serial device to attach to a network. NPort Express works like an
add-on single-port serial board to your PC server, but with one major advantage—the
TCP/IP network. Since the host communicates with the COM port on NPort
Express over a TCP/IP network, you are able to control your asynchronous serial
device from virtually any location.
Although it connects through the virtual link of the Ethernet, the port on NPort
Express is recognized as a real COM port by Windows or a real tty port by Linux.
NPort Express provides both the basic transmit/receive data functions, as well as
RTS, CTS, DTR, DSR, and DCD control signals.
NPort Express can be used with your existing applications that support serial
communication, and come with a utility program providing a simple step-by-step
installation procedure and a maintenance wizard that gives you easy access to your
asynchronous device.
