For engineers and system integrators in test, measurement, and industrial automation, National Instruments (NI) has long been the gold standard for data acquisition and control. One of the most enduring yet complex aspects of NI’s ecosystem is its serial interface hardware. Whether you are managing an old legacy system running Windows XP or building a new test bench on Windows 11, understanding is critical. True NI serial compatibility rests on three pillars:

For legacy systems (pre-2005), the most compatible path is to maintain the original OS (Windows XP embedded) and driver (NI-Serial 1.x). For modern systems, standardize on or USB-232/485 with NI-VISA 20.0 or later, and always validate using the NI Serial Hardware Compatibility Document (available on NI’s knowledge base under ID 4G1D8K).
