National Instruments 780688-01 PXI CAN Interface Module 

National Instruments part number 780688-01 is an identifying part number for the PXI-8513, a PXI Controller Area Network (CAN) Interface Module. It is designed for developing applications with the NI‑XNET driver. NI‑XNET Software‑Selectable CAN Interfaces provide optimal flexibility for CAN development, featuring onboard transceivers for High-Speed Data rate, Low-Speed/Fault Tolerant, Single Wire CAN, and support for any external transceiver. 

The module is ideal for applications requiring real-time, high-speed manipulation of hundreds of CAN frames and signals, such as hardware‑in‑the‑loop simulation, rapid control prototyping, bus monitoring, automation control, and more. The NI‑XNET device-driven DMA engine allows the onboard processor to efficiently transfer CAN frames and signals between the interface and the user program without CPU interruptions. The 780688-01 CAN interface supports multiple physical layer options for flexible application development. For High-Speed CAN with Flexible Data Rate, it uses the NXP TJA1041 or TJA1043 transceiver, supporting a maximum baud rate of 1 Mbps and a minimum baud rate of 40 kbps. 

The CAN_H and CAN_L bus lines can handle voltages ranging from -27 VDC to +40 VDC. For Low-Speed/Fault-Tolerant CAN, the interface utilizes the NXP TJA1054A or TJA1055T transceiver, with a maximum baud rate of 125 kbps and a minimum baud rate of 40 kbps. 

Additionally, the Single Wire CAN option, selectable via software, employs either the NXP AU5790 or the ON Semiconductor NCV7356 transceiver, achieving baud rates from 33.3 kbps to 83.3 kbps. The bus power requirement for this interface ranges from 8 V to 18 V. The PXI-8513 can be identified by two parts. Both have distinction in terms of their ports. The part number 780688-01 differs from the other part number because it has only one port while the other has two.
