NPort 1200/1240 User’s Manual Introduction
1-2
Overview
NPort 1200 Series USB to serial servers provide an extremely convenient means of connecting
serial devices to a PC. In fact, you don’t even need to power-down the PC. Just install the software
that comes with the product, and then connect your serial devices directly to the NPort.
NPort 1200 Series products are compliant with both USB 1.0 and 1.1 specifications, are
compatible with USB 2.0, and meet the 12 Mbps full speed requirement.
More and more peripherals are connected by the Ethernet or USB interface. The problem is how to
integrate these different interfaces. Today’s solution is to connect all devices using the open
standard Ethernet and USB. The total cost of ownership is reduced, not only in short term
hardware investment, but also in long term management and integrating cost.
The NPort 1200 Series supports both bus power and external power via an adapter. Bus power is
adapted for laptop or workstation connections that support 500 mA output for USB devices.
External power is adapted for those USB hubs that can only output 100 mA of current.
