National Instruments 782629-01 Digital I/O Device

National Instruments part number 782629-01 is an identifying part number for the PCIe-6535B, a Digital I/O Device. The NI 782629-01 has an Onboard Clock Frequency Range of 48 Hz to 10 MHz, 32 Data channels, and 6 PFI Channels. This device can continuously stream data over the PCI Express bus, making it an ideal solution for interfacing and testing image sensors or display panels. It is also well-suited for a variety of digital applications, including pattern I/O, change detection, protocol emulation, and custom digital interfacing. This module features selectable voltage levels and per-channel directional control of the digital lines, providing flexibility and precision for diverse application needs. 

This Digital I/O Device offers a low-cost solution for high-throughput operations, making it suitable for applications that require high accuracy, such as testing display panels. The device is compatible with various operating systems and can transfer data patterns synchronized with a clock signal, which can be sourced either internally or externally. This flexibility ensures reliable performance in sensitive applications demanding precise data handling. 

This NI device features an onboard memory size of 2,048 samples (S), utilizing a first-in, first-out (FIFO) structure regardless of port size. It supports two types of data transfer: Direct Memory Access (DMA) and Programmed I/O (for On Demand sample timing type only). For generation, the waveform size must be an integer multiple of 1 S, while for acquisition, the minimum buffer size is 2 S. This configuration ensures efficient and flexible data handling for high-throughput applications. 

The part number 782629-01 has a current drive value of 32 milliamperes for each single-ended digital I/O channel. The maximum data channel toggling rate is 5 MHz, supporting both active edge and inactive edge modes of operation. It requires NI-DAQmx driver software version 9.6.1 or later and can be programmed using software packages or application development environments (ADEs) such as LabVIEW, LabWindows/CVI, or Measurement Studio. Configuration is facilitated through the Measurement & Automation Explorer (MAX) tool.
