National Instruments 777357-02 CAN Interface Device

The 777357-02 CAN Interface Device from National Instruments is the identifying part number for the PCI-CAN/2. It functions as an interface for the controller area network (CAN), with the main purpose being the development of CAN applications. With its sophisticated features, the 777357-02 provides flexible functionality, such as advanced filtering modes, listen-only, and self-reception (echo). Its design complies with the electrical and physical specifications needed for CAN-based in-vehicle (automotive) networks.

The Intel 82527 CAN controller chip allows this interface device to enable several transmission rates up to 1 Mb/s. Its optical isolation up to 500 V and high-speed CAN physical layer, which complies with ISO 11898, guarantee dependable performance even in harsh conditions.

With two physical connector options—DB-9 D-Sub or pluggable screw terminals in the Combicon style—the 777357-02 provides a high degree of connectivity versatility. Furthermore, it permits the CAN physical layer to be powered either internally or externally using bus cable power, with jumpers enabling power source setup for every port.

Through the Real-Time System Integration (RTSI) bus, synchronization between several cards and device integration are made possible. This bus interface allows timing and trigger signals to be sent between the CAN hardware and different National Instruments devices. It consists of a ribbon cable and the National Instruments RTSI bus interface.

A full array of tools for configuration, analysis, and application development are included in the software that comes with the 777357-02. Completely functional APIs that can be tailored to meet particular test and simulation needs are included in this. Quick application development is possible with the frame-based API provided by the NI-CAN driver software that comes with every device.

The 777357-02 provides reliable connectivity and effective data processing in industrial automation systems thanks to its Transceiver (TJA1041) and Microprocessor (Intel 80386EX). With a minimum baud rate of 40 kbps and a maximum baud rate of 1000 Kb/sec, its interface type satisfies ISO 11898 specifications.
