NI USB-6000 User Guide

PFI 0 and PFI 1

Using PFI 0 as a Counter Source

You can configure PFI 0 as a source for counting digital edges. In this mode, rising- or 
falling-edges are counted using a 32-bit counter. For more information, refer to the 

NI USB-6000 

Specifications

 document.

Using PFI 1 to Trigger an Analog Input Acquisition

You can configure an analog input task to wait for an edge on PFI 1 before starting the 
acquisition. To do this, configure the AI Start Trigger source to be PFI 1 and specify either 
rising- or falling-edge. 

Where to Go from Here

This section lists where you can find example programs for the NI USB-6000 and relevant 
documentation.

Example Programs

NI-DAQmx driver software includes example programs to help you get started programming 
with the NI USB-6000. Modify example code and save it in an application, or use examples to 
develop a new application, or add example code to an existing application.

To locate NI software examples, go to 

ni.com/info

 and enter the Info Code 

daqmxexp

For additional examples, refer to 

zone.ni.com

.

To run examples without the device installed, use an NI-DAQmx simulated device. For more 
information, in Measurement & Automation Explorer (MAX), select 

Help»Help Topics»

NI-DAQmx» MAX Help for NI-DAQmx

 and search for simulated devices.
