ND-8511(D) is an 1-port RS-232/422/485 to Ethernet data converter. It is a compact sized communication module that allows users to control serial devices (RS-232/422/485) over a TCP/IP-based Ethernet network. Users may connect host computer systems (Windows98/2000/XP or Linux OSs) to a native serial port through a TCP/IP Ethernet. With one asynchronous serial port connection on one end and a 10/100 Mbps Ethernet connection on the other, ND-8511(D) also allows any device that primarily supports the asynchronous communications protocol to attach to a network. ND-8511(D) works like an add-on single-port serial board to PC servers, but with advantages of the TCP/IP network protocol. With the ND-8511(D), users are able to control asynchronous serial devices from virtually any location. Serial devices connects through a virtual Ethernet link of the, but are recognized as a real COM port by Windows. ND-8511(D) can be used with existing applications, and comes with a utility program.
