National Instruments PXI-8463

The National Instruments PXI-8463 is a robust single-port Controller Area Network (CAN) interface module designed for seamless integration in industrial automation applications. Featuring the Philips SJA1000 CAN controller, the PXI-8463 supports listen-only and self-reception modes, alongside advanced filtering capabilities that facilitate communication with single-wire CAN devices. This module is equipped with the NI-CAN device driver software and incorporates new transceivers for efficient sleep and wake modes. With hardware timing and synchronization features, the PXI-8463 ensures reliable connectivity with NI data acquisition, vision systems, and motion devices, while adhering to ISO 11898 standards for standard (11-bit) and extended (29-bit) arbitration IDs. It maintains operational efficacy at a 100% bus load and data rates of up to 1 Mb/s.

For enhanced safety and noise immunity, the PXI-8463 provides optical isolation of up to 500 V. The module operates using an Intel 80386EX CPU, which directly executes CAN communication protocols, minimizing frame loss due to operating system activities. It features a 9-pin male D-Sub (DB9) connector for straightforward connections to the CAN bus. In multi-device configurations, the PXI-8463 supports synchronization across PXI, PCI, and PCMCIA-CAN devices, making it suitable for various automotive applications, including comfort systems for seat and mirror adjustments.

Additionally, the PXI-8463 includes programming interfaces such as the channel and frame APIs provided by the NI-CAN software, allowing users flexible access to CAN bus communications. For monitoring and analyzing CAN traffic, the module offers the Bus Monitor utility, which presents an easy-to-use interface for logging CAN traffic and displaying essential bus statistics. This makes the PXI-8463 a versatile tool for engineers looking to implement reliable and efficient CAN communications in their automation systems.
