Product Overview

The GPIB‑USB‑HS is a compact plug‑and‑play USB‑to‑GPIB controller adapter from National Instruments. It converts any USB‑equipped PC or laptop into a full‑function IEEE 488.2 GPIB system controller, eliminating the need for internal PCI/PCIe expansion cards inside host computers.

Powered entirely over the USB bus with no external power adapter required, this unit supports both standard GPIB handshake and HS488 high‑speed transfer modes for fast instrument command execution and measurement data acquisition. It implements complete GPIB controller functions including talker/listener, serial/parallel polling, service request handling and device addressing. Native compatibility with LabVIEW, LabWindows/CVI and third‑party test software simplifies automated test‑system development. Two‑color LED indicators show power status and GPIB bus activity for quick visual diagnostics. OEM part numbers: 778927‑01, 780570‑01NI. Original active production is mature status; widely available as surplus / refurbished spare units for legacy test‑system maintenance.

Application Notes

• Connect directly to PC USB port; install NI‑488.2 driver software before instrument communication.
• Maximum total GPIB cable length is 4 m for multi‑instrument bus topology; follow IEEE 488 cabling rules for signal integrity.
• Does not include built‑in GPIB bus analyzer; select GPIB‑USB‑HS+ if protocol capture function is requiredNI.
• Plug‑and‑play design; no DIP‑switch configuration required. Avoid hot‑unplugging during active data transfers.
• For laboratory and indoor test‑bench deployment; keep away from condensation, dust and corrosive gas.
• Typical applications: automated calibration benches, spectrum‑analyzer / oscilloscope / signal‑generator control, production‑line ATE systems, university lab equipment retrofits.
• Confirm driver version compatibility when replacing existing GPIB‑USB‑HS hardware in legacy test setups.
