Overview 3
Chapter 1: Overview
The NDS port server provides communication between peripheral devices and computers
connected to a network. When the NDS is connected to your LAN and to one or more
peripherals, it manages network traffic, routing it to the correct device. For example, the
network diagram below shows how the NDS might be used to allow one or more PCs to
share expensive peripherals or to access peripherals that are located elsewhere on the local
or remote network.
