Clock Routing example "Destination Terminal" = "BoardClk"?

[jchedstrom]

Several of the clock routing examples have a Destination Terminal of "BoardClk". I can't find any documentation on what this is or where it goes. I've attached one of the examples, "Route Clock.vi", which can also be found under Example Finder > Hardware Input and Output > Timing and Synchronization > Signal-based > Route Clock.vi.

The specific hardware I'm experimenting with is the PXIe-6674T. I've looked in the manuals for the PXIe-6674T and the PXIe-1082 chassis. Google has no results.

Hi,

The NI-Sync examples cover a number of modules. Therefore, some of the terminals listed in the examples may not be available on the PXIe-6674T.

BoardClk is only a valid terminal on the PXI-668x modules. This terminal is used internally by the Multi-device PXI_Clk10 Disciplining software. With the PXI-6683(H), this terminal can be used for single-device PXI_Clk10 disciplining as well.

Just looked at the PXI-6683(H) datasheet. It doesn't say anything about "BoardClk", but I've been warned that inconsistencies between hardware/software terminology exist.

Thank you for the quick response and the good explanation.
