PC Controls 14 Instruments Via USB-To-GPIB Adapter

The KUSB-488 transforms any computer with a USB port into a full-function, IEEE 488.2 controller that can control up to 14 programmable GPIB instruments. Designed by Keithley Instruments, the adapter's small size (4.2 by 2.6 by 1.0 in.) and light weight suit it for portable applications that use a laptop computer. It also fits applications in desktop computers with several USB ports available but few, if any, I/O slots.

This adapter works with Windows 2000/XP/Me/98 computers that possess a USB port. USB 2.0-compatible, it offers an IEEE data-transfer rate of 880 kbytes/s. A built-in 2-m USB cable supplies power, eliminating the need for external power sources. Its lack of external DIP switches makes it easy to install and use.

Also, the computer needn't be restarted for the system to recognize the IEEE 488.2 interface. The operating system will automatically recognize and configure the plug-and-play KUSB-488 as soon as it's physically attached to the USB port on the computer.

The KUSB-488 is compatible with Visual Studio and Visual Studio.NET, including Visual C#, LabView, LabWindows, Microsoft Excel VBA, Delphi, and TestPoint. It's IEEE-488.1- and IEEE-488.2-compatible. Connectors are IEEE-488 standard 24-pin and USB standard series-B plug types. Power comes from the USB connection with a maximum drain of 200 mA. It operates from 0°C to 55°C.

The adapter costs $495. It comes with a three-year warranty.
