You can use these defaults or select other sources and destinations for the counter/timer signals
in NI-DAQmx. Refer to
Connecting Counter Signals
in the
NI-DAQmx Help
or the
LabVIEW Help
for more information about how to connect your signals for common counter
measurements and generations. M Series default PFI lines for counter functions are listed in

.
Counter Triggering
Counters support three different triggering actions:
•
Arm Start Trigger
—To begin any counter input or output function, you must first enable,
or arm, the counter. Software can arm a counter or configure counters to be armed on a
hardware signal. Software calls this hardware signal the Arm Start Trigger. Internally,
software routes the Arm Start Trigger to the Counter
n
HW Arm input of the counter.
ArmStart.DigEdge.Edge is not supported on M Series devices and modules.
