National Instruments NI 6323 - Routing Counter N Sample Clock to an Output Terminal; Using an External Source; Using an Internal Source

Chapter 7 Counters
X Series User Manual 7-46 ni.com
If the DAQ device receives a Counter n Sample Clock when the FIFO is
full, it reports an overflow error to the host software.
Using an Internal Source
To use Counter n Sample Clock with an internal source, specify the signal
source and the polarity of the signal. The source can be any of the following
signals:
• DI Sample Clock (di/SampleClock)
• DO Sample Clock (do/SampleClock)
• AI Sample Clock (ai/SampleClock)
• AI Convert Clock (ai/ConvertClock)
• AO Sample Clock (ao/SampleClock)
• DI Change Detection output
Several other internal signals can be routed to Counter n Sample Clock
through internal routes. Refer to Device Routing in MAX in the NI-DAQmx
Help or the LabVIEW Help for more information.
Using an External Source
You can route any of the following signals as Counter n Sample Clock:
• PFI <0..15>
•RTSI <0..7>
•PXI_STAR
• PXIe-DSTAR<A,B>
• Analog Comparison Event
You can sample data on the rising or falling edge of Counter n Sample
Clock.
Routing Counter n Sample Clock to an Output
Terminal
You can route Counter n Sample Clock out to any PFI <0..15> terminal.
The PFI circuitry inverts the polarity of Counter n Sample Clock before
driving the PFI terminal.
