GPIB Controller for Hi-Speed USB

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.
