Welcome to Moxa NPort Server Lite, an Industrial Serial Device Server that
greatly enhances the ability of a Windows 95/98/Me/NT/2000/XP host to control
multiple serial devices over a TCP/IP based Ethernet network.
This chapter is an introduction to NPort Server Lite and includes the following:

NPort Server Lite provides a data communications solution for connecting
Windows hosts to multiple asynchronous RS-232 (models DE-301/302/304) or
RS-422/485 (models DE-331/332/334) serial ports through a TCP/IP network.
Each model has one (DE-301/331), two (DE-302/332), or four (DE-304/334)
asynchronous serial port connections on one side, and one 10/100 Mbps Ethernet
connection on the other, allowing any device that supports the asynchronous
communications protocol to attach to a network. NPort Server Lite works like an
add-on multiport serial board to the Windows host, but with one major
advantage—the TCP/IP network. Since the Windows host communicates with
the COM ports on NPort Server Lite over a TCP/IP network, you are able to
control asynchronous serial devices from virtually anywhere in the world.
Although it connects through the virtual link of the Ethernet, the ports on NPort
Server Lite are recognized as Real COM ports by the Windows operating system.
NPort Server Lite provides both the basic transmit/receive data functions, as well
as RTS, CTS, DTR, DSR, and DCD control signals.
NPort Server Lite can be used with your existing applications that support serial
communication. It also comes with a utility program providing a simple
step-by-step installation procedure, and a maintenance wizard that gives you
easy access to your asynchronous devices.
