 I will never forget Dean's opening lines: "I want you to know that I am here under protest. I believe that everything you are doing here is repugnant and ethically wrong. And now I am going to tell you why..." And for the next 35 minutes, that is exactly what he did. - dlavery [more] |

| Can the USB-6009 store data externally to allow me to view it later? |
| No, the 6009 does not have the ability to store data on-board; to do so you would need something a bit beyond the capabilities of the NI USB-6009 DAQ device. In order to do everything the 6009 is capable of doing on its own you would really need something with an on-board processor. The DAQ device should be looked at very much like a steroid-infused IFI controller that instead of controlling via a program you upload to it you control it via the USB interface with a PC or LabVIEW-capable device. The DAQ device, in conjunction with LabVIEW, gives you the ability to analyze sensors, tweak PID control loops, simulate sensors, and perform advanced analysis and control tasks not currently supported by available tools (among a myriad of others). With what you can learn with the DAQ device you will be able to more intelligently tweak/control your robot through conventional means for competition. |
| What software do I need to install in order to allow me to use the USB-6009 DAQ device in LabVIEW? |
| NI-DAQmx is a required driver package for the NI USB-6009 DAQ device. It comes in two flavors: NI-DAQmx and NI-DAQmx Base. The NI USB-6009 uses NI-DAQmx on Windows and NI-DAQmx Base for the Mac. The latest version of NI-DAQmx that is packaged with your hardware on the accompanying CD is probably 7.5 (depending on when the CD was kitted with the hardware). However, if you're using LabVIEW 8.0 (including the LabVIEW 8.0 Student Edition) you will most likely need to download NI-DAQmx 8.0 for Windows, or NI-DAQmx Base 1.5 for MacOSX, from the National Instruments website (466MB / 86.6MB). You can navigate to:
http://www.ni.com/dataacquisition/nidaqmx.htm
and click on the "Download NI-DAQmx 8.0" link on the right just below the graphic to get to the download site for both versions. Be sure to install NI-DAQmx or NI-DAQmx Base AFTER installing LabVIEW 8.0 Student Edition. |
| What's the maximum input voltage for the NI USB-6009? |
| The NI USB-6009 can read up to 10V when read single-ended mode (reference to ground), or 20V when read in differential mode (two wires with the voltage being observed is the difference of the voltages on the wires). It is important to note that you MUST NOT exceed these voltages in each mode, as damage will occur if the voltages exceed these limits. |
