Overview
The compact NI GPIB-USB-HS transforms any computer with a USB
port into a full-function, IEEE 488.2 controller that can control up to 14
programmable GPIB instruments. The small size and light weight of this
controller make it ideal for portable applications using a laptop computer
or other applications in which the computer has no available internal I/O
slots. The GPIB-USB-HS works with Windows Vista/XP/2000/Me/98,
Mac OS X, and Linux computers with a USB port.
This controller is easy to install and use because there are no external
DIP switches and you do not need to restart your computer for the
system to recognize your IEEE 488.2 interface. It is a plug-and-play
interface that the OS automatically recognizes and configures as soon
as you physically attach it to the USB port on your computer. With the
GPIB-USB-HS, you can get up and running quickly, so you can focus on
developing your instrument control applications.
The GPIB-USB-HS is the first GPIB interface to take advantage of the
superior performance of Hi-Speed USB signaling (480 Mb/s). Plugging it
into a Hi-Speed USB port provides industry-leading GPIB performance
using both the standard and high-speed IEEE 488.1 handshake.
Using a TNT family talker/listener/controller IEEE 488.2 ASIC, the
GPIB-USB-HS implements the full range of GPIB controller functions,
including those required and recommended by IEEE 488.2. It also
implements normal and extended talker and listener, serial and parallel
polling, service request, and pass/receive control functions. Drawing
power directly from the USB port, the GPIB-USB-HS requires no external
power input.
With NI-488.2, you get a robust driver with additional utilities and
wizards that help you troubleshoot your applications and decrease your
development time (see Figure 2). Furthermore, you maintain compatibility
with existing systems. Applications previously written for other National
Instruments GPIB controllers can run unmodified with the GPIB-USB-HS.

Connecting the GPIB-USB-HS
to Your Instruments
This controller does not require a GPIB cable to connect to your
instruments. You can attach it directly to the GPIB port on your instrument
and then connect the USB cable to the USB port on your computer. If you
have multiple instruments in a daisy-chain or star configuration, attach
any cables that connect to the other instruments first, and then
piggyback the GPIB-USB-HS as the last connector in the stack.
