National Instruments 777357-01 CAN Interface Device

The part number 777357-01 from National Instruments is the identifying part number for the PCI-CAN CAN Interface Device. This interface device is designed for the PCI, PXI, and PCMCIA series of modules, controllers, and sensors. CAN interfaces meet the physical and electrical requirements for in-vehicle automotive networks based on CAN. All CAN interfaces include NI-CAN device driver software, with which you can import CAN channels from Vector database files or create them in an easy-to-use utility and program using a high-level API. 

With a National Instruments CAN interface and NI-CAN software, you can use a desktop, industrial, or notebook PC running Windows for a variety of CAN applications, including automotive testing and diagnostics, prototype design, factory automation, and machine control. The CAN physical layer connects the CAN controller to the physical bus wires. The boards contain the PCI and PXI physical layers. They are powered internally (from the boards) via a DC-DC converter, and optically isolated up to 500 V. This isolation protects your NI-CAN hardware and the PC it is installed in from being damaged by high-voltage spikes on the CAN bus.

This module has one port with a data transfer rate of 1000 kb per second, and includes the TJA1041 transceiver. You can communicate with a specific CAN channel without programming using Test Panel, a simple debugging tool to experiment with CAN channels. Using a graphical interface, the tool reads CAN data in engineering units and plots or writes to the device. To quickly monitor all CAN bus traffic, use the Bus Monitor, a utility that provides an easy-to-use interface to view all CAN traffic and log it to disk. It also provides options to control, display, and view bus statistics.

PCI-CAN and PXI-846x interfaces have a 9-pin male D-Sub (DB9) connector for each port.  PCMCIA-CAN cables have both a 9-pin male D-Sub and Combicon-style pluggable screw terminal connector for each port. The National Instruments CAN Device Simulator, when communicating with NI CAN and data acquisition (DAQ) hardware on a PC, provides a tool to demonstrate the concepts of CAN communication, DAQ, and CAN/DAQ synchronization.
