NI-Digital does not validate Bit Order for Capture Engine reconfiguration


If multiple capture waveforms are used within a single session, the NI-Digital driver should validate Sample Width, Pins, Waveform Type (Serial/Parallel), and Bit Order (MSB/LSB) to determine if the Capture Engine must be reconfigured. The Bit Order setting is not being validated. This means that if the two capture waveform configurations differ in Bit Order and the other 3 settings are consistent, then no reconfiguration will take place and the data for one of the waveforms will be returned with incorrect bit order..

Workaround: Configure all waveforms to be a consistent Bit Order and reorder in software as necessary. Alternatively, close and create a new NI-Digital session between waveforms with settings that differ only in Bit Order.

Return		Loading large patterns in a 32-bit process runs out of memory
As a result of limited system memory in a 32-bit process, loading a large pattern in a 32-bit process might fail.

Workaround: Split large patterns loaded in a 32-bit process into patterns that are small enough to fit into the available system memory.

Return		NI Example Finder does not filter for PXIe-6570 hardware
Using hardware filtering in the NI Example Finder does not return any examples that support the PXIe-6570.

Workaround: To find PXIe-6570 examples, use the NI Example Finder search feature with "6570" as the keyword or browse the task structure under Hardware Input and Output»Modular Instruments»NI-Digital Pattern Driver.
