National Instruments 777707-01

Part Number: 777707-01

The National Instruments 777707-01 is a high-performance PXI-CAN Interface Module, designated as the PXI-8461/1. This module is engineered to facilitate high-speed communication within Controller Area Network (CAN) systems, supporting transfer rates of up to 1 Mbps, making it ideal for applications such as Antilock Brake Systems (ABS), motor control modules, and emissions systems. In addition to standard high-speed capabilities, the module supports low-speed and fault-tolerant CAN communication, enabling data transmission rates of up to 125 kb/s, and includes advanced fault confinement features.

The 777707-01 allows for seamless interaction with multiple CAN channels through the Test Panel, a user-friendly troubleshooting and experimentation tool that enables users to visualize CAN data in engineering units, perform data plotting, and save data to the device. For comprehensive monitoring of CAN bus activity, the Bus Monitor utility delivers a straightforward interface for tracking, controlling, and logging all CAN traffic, along with the ability to view detailed bus statistics.

The module is compatible with the NI-CAN software suite, which is designed for Windows operating systems including Windows 2000, NT, XP, Me, and 98. This software package includes 32-bit device drivers, facilitating application development in environments such as NI LabVIEW and LabWindows/CVI, alongside firmware that operates on an embedded Intel 80386EX chip to support time-critical functionalities.

The National Instruments 777707-01 further accommodates CAN single-cable interfaces, allowing for communication with higher-speed devices at rates of 33.3 kb/s, or 88.3 kb/s in rapid mode. Typical applications for single-cable configurations include automotive comfort functions, such as seat and mirror adjustments. Users can configure the software-selectable CAN interface for a range of operational modes, including rapid communication, low-speed/fault-tolerant operation, or single-cable mode, with multiple transceiver hardware options available to meet diverse application requirements.

Technical specifications include a maximum transfer rate of 1,000 kb/s, a single port configuration, a DB9 male I/O connector for channel connections, a typical current draw of 800 mA, and support for flexible baud rates of 125, 250, and 500 kb/s, all operable within a temperature range of 0 to 55 °C. The module dimensions are 6.3 x 3.9 inches, making it a compact solution for integrated CAN communication needs.
