Terminal Name Equivalents
With NI-DAQmx, National Instruments has revised its terminal names
so they are easier to understand and more consistent among National
Instruments hardware and software products. The revised terminal names
used in this document are usually similar to the names they replace. Refer
to Table 1-5 for a list of Traditional NI-DAQ (Legacy) terminal names and
their NI-DAQmx equivalents.
PFI 8/CTR 0 SRC D GND Input PFI 8—As an input, this pin is a PFI.
Output Counter 0 Source Signal—As an output, this pin is the
Ctr0Source signal. This signal reflects the actual source
connected to the general-purpose Counter 0.
PFI 9/CTR 0
GATE D GND Input PFI 9—As an input, this pin is a PFI.
Output Counter 0 Gate Signal—As an output, this pin is the
Ctr0Gate signal. This signal reflects the actual gate signal
connected to the general-purpose Counter 0.
CTR 1 OUT D GND Input Counter 1 Output Signal—As an input, this pin can be
used to route signals directly to the RTSI bus.
Output As an output, this pin emits the Ctr0InternalOutput signal.
FREQ OUT/USER
<1..2> D GND Output Frequency Output Signal—This output is from the
frequency generator.
I/O User <1..2>—On BNC devices, these signals connect
directly from a screw terminal to a BNC. For example, if
you connect CTR 0 OUT to the USER 1 screw terminal
with a wire, the Ctr0Out signal also is driven to the User 1
BNC.
