173559 You cannot specify a delay for the global software trigger.
242012 If Set Time is called, the time will be successfully set as directed no matter what the current time reference has been set to.

ID Known Issue
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.

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
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
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The time reference offset value is no longer updated when the 1588 node switches to master.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
366243
 
 Return
The Mobile Mode property may be inconsistent on an NI PXI-6682 after restart.
     After a reboot, test panels for the board may falsely report that the board is in stationary mode.
     
     Workaround: N/A

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 jitter on real-time systems.
           
     Workaround: National Instruments recommends that you do not use the NI PXI-668x modules for applications sensitive to jitter.

 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.
