Routing Frequency Output to a Terminal
You can route Frequency Output to any output PFI <6..9> terminal. All
PFIs are set to high-impedance at startup.
Default Counter Terminals
By default, NI-DAQmx routes the counter/timer inputs and outputs to the
PFI pins, shown in Table 7-4.
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 8.x Help
for more information on
how to connect your signals for common counter measurements and
generations. M Series default PFI lines for counter functions are listed in
Physical Channels
in the
NI-DAQmx Help
or the
LabVIEW 8.x Help
.
