Overview
Connect a compact NPort 1200 Series product to your computer—you don’t even have to
power-down—install the supplied software, and then connect your serial devices directly to the NPort.
In minutes, and with state-of-the-art accuracy, you’re capturing data—temperature, pressure, sound
level, whatever you need. And you’ve done this without programming, without opening up your PC,
without even thinking about IRQs, board configuration, power requirements, or connection schemes.
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.
