The NI GPIB-USB-HS Controller for USB transforms any computer with a USB port into a fully functional IEEE 488.2 GPIB controller. This bus-powered device leverages Hi-Speed USB 2.0 performance to command up to 14 programmable GPIB instruments without requiring external cabling—instruments connect directly to the IEEE 488 24-pin connector. The controller supports both standard and high-speed IEEE 488.1 handshake protocols, delivering data transfer rates up to 1830 kBytes/s in 3-wire mode and 7230 kBytes/s in HS488 mode. Compact and lightweight at 10.7 cm × 6.6 cm × 2.6 cm (180 g), it operates from USB bus power (typical 140 mA, peak 500 mA at +5 V VBUS). Dual LEDs indicate connection status and GPIB activity.
