1588 Synchronization Drifts Away with Time when using a 10 Mbps Router with the PXI-6682
I'm doing 1588 synchronization with the PXI-6682 but I've noticed that synchronization gets worse with time (the slave continues to drift away from the master). Looking at the "offset from master" property for the slave, the value will look normal (under 100ns) most of the time, but you'll

Special Considerations for PFI0 on the PXI-6682
PFI0 seems to behave inconsistently. Sometimes I get an immediate timestamp even if my input hasn't changed. The same problem happens if I connect PFI0 to a destination, the initial state seems to be floating. Do I have a problem with PFI0?

'Wait Until' Trigger Produces Unexpected Signal
The script pauses by generating the last 'n' samples when the script reaches a 'wait until' trigger. This is not an issue on the first 'wait until' trigger, but if a signal is generated when the 'wait' instruction occurs, some data is generated.

Why is Incorrect Data Retuned When Communicating via Interactive Mode with NI-RIO 2.1.3 or Earlier?
I Have and NI RIO application that performs array read/writes on a cRIO 901x controller that has NI RIO 2.3 and LabVIEW Real-Time 8.5 installed that returns incorrect data. When running in host interface mode, I get a LabVIEW Real-Time error about incompatible versions on the remote target

Ghosting on Motion Controller Analog Inputs
I have an NI-73xx Motion controller and I am using the analog input to read an analog signal. I have hooked up my signal to analog input channel 3, but in my program I am reading from analog input 1. Even though I am reading from a different channel than what I have connected, I still see

Why do I see Spurious Returns when using multiple Wait on IRQ Nodes on VxWorks Real Time Targets?
NI-RIO 2.3 with LabVIEW 8.5 supports multiple Wait on IRQ nodes in a single VI, however, I see spurious returns from the "Wait on IRQ" Method Node when using cRIO-901x Controllers. This does not occur on my cRIO-900x Controllers or any other Pharlap based Real-Time controller. Why does this
