Maximizing the Performance of the NI 6534 Digital I/O Device

The NI 6534 is a 32-bit, parallel, high-speed digital I/O device that uses the DAQ-DIO ASIC, a high-performance digital I/O interface designed by National Instruments. In addition to the DAQ-DIO, the NI 6534 also has large onboard memory buffers that allow pattern I/O operations to be carried out at high deterministic rates.
