Specifications
Introduction
The ND-8511 is a single-port RS-232/422/485 to Ethernet data converter. This compact-sized communication module
allows users to control serial devices (RS-232/422/485) over a TCP/IP-based Ethernet network. Users may connect
host computer systems (Windows/2000/XP) 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, the ND-8511 also allows
any device that supports asynchronous communications protocol to attach to a network.The ND-8511 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,
you can control asynchronous serial devices from virtually any location. Serial devices connects through a virtual Ethernet
link, but are recognized as a real COM port by Windows.The ND-8511 can be used with existing applications,
and includes a utility program providing a simple step-by-step installation procedure and maintenance wizard that
offers easy access to asynchronous devices.
