Each issue appears as a row in the table and includes the following fields:
ID | Known Issue | |||||
---|---|---|---|---|---|---|
327476 | In certain cases, the clock frequency or requested source may not be the same clock used when acquiring or generating data on NI 6545/6548 devices. Workaround: Install NI-HSDIO 1.8.1.
| |||||
307658 | In NI 6555/6556 devices, if both acquisition and generation sessions are open when you conduct self-calibration in one session, the data from the other session is invalid. Self-calibration of NI 6555/6556 devices uses both acquisition and generation sessions. Therefore, if you have both sessions open when you conduct self-calibration in one session, the data from the other session is invalid. Workaround: Complete all measurements before or after self-calibrating your NI 6555/6556.
| |||||
306800 | Cannot perform self-calibration in MAX on the NI 6555/6556 devices. If you try to self-calibrate an NI 6555/6556 device in MAX it returns error -200445. Self-calibration of NI 6555/6556 devices takes between 15 and 20 minutes, which is longer than the allotted time period for self-calibration in MAX. Workaround: Self-calibrate your NI 6555/6556 device using the NI-HSDIO self-calibration VIs or functions instead.

306810 | NI-HSDIO generates an error with an unknown status code when allocating streaming waveforms that are not 128-byte aligned. Workaround: When allocating streaming waveforms, ensure that they are 128-byte aligned.
| |||||
306807 | Error -219001 may occur on NI PXIe-6544/6545/6547/6548 devices when scynchronizing acquisitions using NI-TClk. For the NI PXIe-6544/6545/6547/6548, internal error -219001 may occur intermittently when synchronizing multiple acquisitions using NI-TClk at rates below 5 MHz. Workaround: If this error occurs, consider oversampling by configuring your acquisition with a higher sample rate. For more information, contact NI Technical Support at ni.com/support.
| |||||
306808 | The NI PXIe-6544/6545/6547/6548 may not utilize the full bandwidth of the PCI Express bus. In rare cases, the NI PXIe-6544/6545/6547/6548 may not utilize the full bandwidth of the PXI Express bus. These modules are x4 PXI Express devices, which are capable of using up to four 2.5 Gbps bus data lanes. Start-time negotiation between the PXI Express controller and the device may result in the device using only one or two data lanes. The result is reduced performance when reading or writing large amounts of waveform data. Workaround: This situation is normally corrected the next time you restart your system. For more information, contact NI Technical Support at ni.com/support.
| |||||
306801 | When using 64-bit user mode, NI-HSDIO does not support NI-HWS. Workaround: Contact NI Technical Support at ni.com/support.
| |||||
306803 | When using a MXI connection, some NI PXI Express devices may not be recognized after a shutdown. Workaround: When you turn off your computer, either restart or power cycle your chassis before powering up your computer again.
| |||||
306802 | Building NI-HSDIO-linked 64-bit user applications requires an additional linker library directory and dependency. For building NI-HSDIO examples in 64-bit user mode applications that link to NI-HSDIO, you must add $(NIIVIPATH32)\Lib_x64 as an additional linker library directory and add niHSDIO.lib as an additional linker dependency. Workaround: Add $(NIIVIPATH32)\Lib_x64 as an additional linker library directory and add niHSDIO.lib as an additional linker dependency.
| |||||
306813 | MAX might not display NI-HSDIO devices when deploying to a LabVIEW Real-Time target. NI-HSDIO devices might not be visible in Measurement & Automation Explorer (MAX) when deploying to a LabVIEW Real-Time target. Workaround: For more information, search ni.com/kb using the code 4RCAMBD4 or contact NI Technical Support at ni.com/support.
| |||||
306816 | Some Windows power management modes terminate in-progress NI-HSDIO operations. NI recommends that you disable Windows power management modes, such as sleep, standby, and hibernate when using this product. These modes terminate any NI-HSDIO operation in progress. Notice that in Windows 7/Vista or on a laptop computer, the default power management settings are likely to enable sleep mode. Workaround: Disable Windows power management modes. For more information, contact NI Technical Support at ni.com/support.
| |||||
306817 | When installing NI-HSDIO in silent mode from the command line, your computer automatically trusts NI software. When you run setup.exe to install the software from the DVD, you are prompted to choose whether you want to always trust software from National Instruments. If you do not select this option, your installation may be interrupted by one or more Microsoft Windows security dialog boxes. However, if you run the installer in silent mode from the command line, you will not receive this prompt, and the installer will automatically install NI's Software Publisher Certificate to the your Windows Trusted Publisher Store. Workaround: If you do not want to make this change to your Windows Trusted Publisher Store, do not choose this installation method. For more information, contact NI Technical Support at ni.com/support.
