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.
