National Instruments 782631-01 32-Channel Digital I/O Device

The National Instruments 782631-01, also known as the PCle-6537B, is a 32-channel digital I/O device designed for continuous data streaming over the PCI Express bus. This device is well-suited for interfacing and testing image sensors or display panels, offering versatile applications such as change detection, protocol emulation, pattern I/O, and custom digital interfacing. Each of the 32 data channels allows per-channel direction control that provides flexible data handling capabilities. The 782631-01 device also includes 6 PFI channels and 8 bidirectional RTSI trigger channels which improves its adaptability for complex signal interfacing.

The 782631-01 supports single-ended signal generation with selectable voltages of 2.5V, 3.3V, and 5V. The output impedance is 50 Ohms, and the device is protected against shorts to any voltage between 0V and 5V. This top-quality voltage protection makes the device reliable in various operational environments. Pattern generation timing for data and PFI channels allows a maximum data channel toggle rate of 25 MHz, with a minimum hold time of 1.1 ns relative to PFI 4 channels. For pattern acquisition, the setup time relative to PFI 5 channels is 2.8 ns, with a hold time of 1.5 ns.

The onboard memory size for this Ni 782631-01 is 2,048 samples. The device utilizes DMA and programmed I/O transfer types. The device is energy-efficient and consumes only 6W of power. The compact dimensions (18.1 cm × 2.2 cm × 12.6 cm) and light weight (107.7 g) make it easy to integrate into various system configurations. The NI DAQmx driver software (version 9.6.1 or later) supports application development environments such as National Instruments LabVIEW, LabWindows/CVI, and Microsoft Visual Studio that provides extensive programming flexibility.

Operating conditions for the device include a temperature range from 0 to +45 degree Celsius and the storage temperature ranges between -20 to +70 degree Celsius. The 782631-01 device operates within 10% to 90% relative humidity (non-condensing) and is functional at altitudes up to 2,000 meters above sea level. The device meets stringent safety standards (IEC 61010-1, EN 61010-1, UL 61010-1, CSA 61010-1) and electromagnetic compatibility standards (EN 61326, EN 55011, AS/NZS CISPR 11, FCC 47 CFR Part 15B, ICES-001).
