4, Installation and Configuration Guide

1. Driver installation steps
Download driver: Visit the NI official website and select the NI-488.2 14.0+version that matches the operating system.
Connecting devices: Insert GPIB-UB-HS+into the computer's USB port, and the system will automatically recognize it.
Configure Address: Set GPIB primary address (default address is 0) through Measurement&Automation Explorer.

5, Summary
NI GPIB-US-HS+has become the preferred solution for GPIB to USB devices due to its high-speed transmission, low-power design, and built-in analysis capabilities. Whether building an automated testing system or conducting on-site instrument debugging, this equipment can provide efficient and reliable solutions. Combined with NI's comprehensive software ecosystem, users can quickly achieve full process development from hardware connection to system integration.
