Product Introduction
The NI PXI-8512 is a single-port high-speed CAN communication interface module designed for PXI-based automotive, industrial automation, and embedded control applications. Powered by NI-XNET technology, the PXI-8512 provides deterministic Controller Area Network (CAN) communication with hardware-accelerated message processing, making it suitable for ECU development, CAN bus monitoring, diagnostics, Hardware-in-the-Loop (HIL) simulation, and automated production testing.
Supporting both CAN 2.0A and CAN 2.0B protocols with baud rates up to 1 Mb/s, the PXI-8512 enables reliable communication with electronic control units (ECUs), PLCs, industrial controllers, and embedded CAN devices while integrating seamlessly into PXI automated test systems.
Product Overview
The PXI-8512 belongs to the NI-XNET communication interface family and is optimized for reliable CAN communication with minimal CPU overhead. The onboard NI-XNET hardware engine performs message buffering, timestamping, cyclic frame transmission, and bus synchronization independently of the host processor.
Its PXI modular architecture allows engineers to combine CAN communication with multifunction DAQ modules, digital instruments, RF analyzers, switching modules, and real-time controllers within a single automated test platform.
The PXI-8512 is fully supported by NI-XNET software and integrates with LabVIEW, VeriStand, TestStand, LabWindows/CVI, C/C++, .NET, and Python development environments.
