The National Instruments PXI-6534 Digital I/O Module (Part Number: 778288-01) is a high-performance, 32-bit parallel I/O interface designed for seamless integration with 5V TTL/CMOS devices. This module excels in pattern I/O and high-speed data transfer, supporting a variety of handshaking protocols at speeds up to 80 MB/s. The PXI-6534 features extensive onboard memory, customizable power-up states, start and stop triggering, pattern matching, and change detection. Users can configure the 32 I/O lines as individual single-channel inputs or outputs or aggregate them into 8, 16, or 32-bit ports for more complex operations.

Each of the 32 digital I/O channels operates with a maximum clock rate of 20 MHz, capable of sinking or sourcing up to 24 mA at logic levels. The lines are diode-terminated, allowing for robust input signal damping. Users can define each channel for static or unstrobed I/O, enabling precise control during operations. The module's handshaking capability ensures that data transfer occurs only when both the PXI-6534 and the peripheral devices are ready. Connectivity is facilitated through a 68-pin male SCSI-II connector, and the device's compact dimensions are 6.4 x 3.9 inches.

The PXI-6534 is fully supported by the NI-DAQ driver software, compatible with various application development environments (ADEs) such as LabVIEW, LabWindows/CVI, and Measurement Studio, facilitating quick data acquisition and application development. Automatic configuration is easily accomplished using the Measurement & Automation Explorer (MAX) tool.
