PXI Module, FlexRIO Adaptor, Serial

The NI PXI FlexRIO Adapter, Serial Modules provide a modular and high-performance solution for implementing serial communication interfaces within PXI-based test and measurement systems. Designed to pair with NI FlexRIO FPGA modules, these adapters enable deterministic, low-latency communication and precise timing control for standard and custom serial protocols. By leveraging FPGA-based processing and the PXI Express backplane, FlexRIO serial adapters support hardware-timed execution, high data throughput, and tight synchronization with other PXI instruments. This makes them ideal for implementing interfaces such as SPI, I²C, UART, LVDS, and proprietary serial protocols in applications that require custom timing or non-standard signaling. NI PXI FlexRIO serial adapter hardware is widely used in semiconductor validation, aerospace and defense systems, automotive electronics testing, and advanced R&D environments. The modular architecture allows engineers to adapt quickly to evolving interface requirements while maintaining system scalability, signal integrity, and repeatable performance.
