IDKnown Issue
222651

Return
The NI PXI-6682 is incorrectly identified as a VISA device on a 64-bit host computer with more than 4 GB of RAM.

Workaround: N/A

Reported Version: 3.2  Resolved Version: 3.2.3  Added: 06/01/2011
173555

Return
If a large time adjustment occurs, any PPS or clock being generated will not be aligned with the new time of the board.

Workaround: Monitor for large time adjustments (snaps) and restart clocks each time such an adjustment occurs. You also can use future time events instead of clocks.

Reported Version: 3.0  Resolved Version: N/A  Added: 08/04/2014
173559

Return
You cannot specify a delay for the global software trigger.
The global software trigger fires on the next riding edge of the clock even if you specify a delay.

Workaround: N/A

Reported Version: 3.1  Resolved Version: N/A  Added: 08/04/2014
242012

Return
If Set Time is called, the time will be successfully set as directed no matter what the current time reference has been set to.
Some time references, such as GPS and IRIG should not allow setting the time.

Workaround: N/A

Reported Version: 3.3  Resolved Version: N/A  Added: 08/04/2014
246967

Return
Enabling or disabling the PFI 10kOhm Termination on the NI PXI-6674T affects PFI threshold value.
Enabling the 10kOhm termination causes the threshold voltage to decrease slightly, while disabling the 10kOhm termination causes the threshold voltage to increase slightly.

Workaround: N/A

Reported Version: 3.2  Resolved Version: 3.3  Added: 08/04/2014
246972

Return
On the NI PXIe-6674T, setting 10kOhm Termination on PF1 causes an error.
If the threshold voltage for PFI1 is set close to its maximum value, enabling PFI1 10kOhm termination causes the following calls to hang: Get PFI Threshold Voltage, Set PFI Threshold Voltage, and Enable PFI1 10kOhm termination.

Workaround: N/A

Reported Version: 3.2  Resolved Version: 3.3  Added: 08/04/2014
322232

Return
Setting the User LED State property on an NI PXIe-6674T results in error -1074118653: This operation requires a feature that is not supported.

Workaround: N/A

Reported Version: 3.2  Resolved Version: 3.4  Added: 08/04/2014
327791

Return
NI-Sync may use cached MAX configuration data.
If you place an NI PXI-6682 module in a slot which previously housed a different NI PXI-6682, NI-Sync will use the the MAX configuration data from the previous module.

Workaround: Set the NI PXI-6682 to recalculate the position on reboot.

Reported Version: 3.3  Resolved Version: N/A  Added: 08/04/2014
330043

Return
Reading Future Time Events on NI PXI-668x Modules may cause a crash.
Enabling trigger timestamps on a line while the hardware timestamps a trigger on a different line may result in a system crash.

Workaround: N/A

Reported Version: 3.0  Resolved Version: 3.4  Added: 08/04/2014
363033

Return
The time reference offset value is no longer updated when the 1588 node switches to master.

Workaround: Do not query the property when the 1588 node is the master and primary time reference.

Reported Version: 3.4  Resolved Version: N/A  Added: 08/04/2014
364088

Return
Running niSync Start 1588.vi resets all the 1588 properties to default.
When you run the niSync Start 1588 VI, all 1588 properties are reset to default, including Log Sync Interval, Priority 1, and Priority 2. Any settings configured prior to running this VI are erased.

Workaround: N/A

Reported Version: 3.3  Resolved Version: 3.4  Added: 08/04/2014
365208

Return
The NI PXIe-6674(T) self-test fails with error -201427.
Due to an intermittent error in initialization of the device, an NI PXIe-6674(T) self-test results in error -201427: The specified device is not supported within the NI-DAQmx API.

Workaround: Reboot the system.

Reported Version: 3.3  Resolved Version: 3.4  Added: 08/04/2014
366243

Return
The Mobile Mode property may be inconsistent on an NI PXI-6682 after restart.

Workaround: N/A

Reported Version: 3.4  Resolved Version: N/A  Added: 08/04/2014
367753

Return
Resetting the PXI-6682(H) or PCI-1588 multiple times cause errors
Multiple asynchronous resets to the PXI-6682(H) or PCI-1588 cause a variety of errors and may even result in a system hang or crash.

Workaround: N/A

Reported Version: 3.4  Resolved Version: 3.4  Added: 08/04/2014
381561

Return
The network adapter on the NI PXI-6682 initializes with incorrect settings.

Workaround: N/A

Reported Version: 3.3.5  Resolved Version: 3.4  Added: 08/04/2014
385300

Return
When in polling mode, the NI PXI-6682 and NI PXI-6683 modules fail to acquire an IP address.

41819
4E3AJQRX


Return
The PXI-6682 and PXI-6683 may revert to using the TCXO (because Clk10 is no longer available) without notifying the user
The PXI-6682 and PXI-6683 have a protection mechanism so that if they are running off Clk10 and Clk10 disappears, the card will revert to using the TCXO, and will not hang. However, because there is no notification, users who have configured their board to run off Clk10 might unknowingly have a board running off its own TCXO.

Workaround: N/A

Reported Version: 3.0  Resolved Version: N/A  Added: 08/04/2014
438783

Return
The NI PXI-6682 and NI PXI-6683 modules may cause excessive jitter on real-time systems.

Workaround: National Instruments recommends that you carefully evaluate the performance of applications sensitive to jitter that use NI PXI-668x modules to verify that jitter requirements are met.

Reported Version: 3.3  Resolved Version: 14.5  Added: 08/04/2014
439127

Return
The NI PXI-6683(H) only verifies the first 6 characters of the calibration password, even if the password is longer than 6 characters.

Workaround: N/A

Reported Version: 3.4.1  Resolved Version: N/A  Added: 08/04/2014
439129

Return
Modifying the calibration password updates the calibration timestamp.

Workaround: N/A

Reported Version: 3.4.1  Resolved Version: N/A  Added: 08/04/2014
506257

Return
The NI PXI-6683 Ethernet driver may cause real-time systems to hang or crash.

Workaround: Disable the Ethernet adapter on the NI PXI-6683 to prevent the system hang from occurring.
