The National Instruments PXI-8464/1 (Part Number: 778783-01) is a high-performance PXI Controller Area Network (CAN) interface designed to facilitate the integration of simple and complex I/O systems into a CAN bus environment. This module employs software-selectable transceivers, including TJA1041, TJA1054A, and AU5790, allowing for flexible communication with various low-speed CAN devices. The PXI-8464/1 supports a maximum transfer rate of 1,000 kb/s and is compliant with the CompactPCI mechanical standards, ensuring compatibility with 3U PXI instrumentation systems.
The interface allows seamless communication with the NI FP-1300, a CAN network interface module capable of expanding system capabilities by supporting up to 50 I/O modules across multiple FP-1300 devices connected to a single CAN port. Each FP-1300 is fully configurable, enabling users to define the message ID, frame configuration, and data allocation specific to their application needs. It is important to note that proper termination is essential for maintaining signal integrity, with recommended total RTH and RTL values ranging between 100 to 500 Ω for low-speed networks.
While the PXI-8464/1 has been marked as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves, along with accompanying user and maintenance manuals for comprehensive operational guidance.
