Symptoms

DI-720, DI-722, and DI-730 series USB drivers do not automatically install under Windows 7.

Cause

64-bit Windows 7 and 64-bit Windows Vista will not automatically install 'unsigned' drivers.

Resolution

To resolve this issue:

Manually Install the drivers

Dataq Instruments Software

Download the Drivers

Download the 64-bit DI-720/730 USB drivers from DATAQ Instruments (please note - this is a dead link and no longer available for download - for the latest drivers please submit a support ticket).

Disable Driver Signature Enforcement

When installing a DI-720/730 series, USB instrument on a 64-bit Windows Vista/7 PC, begin by disabling driver signature enforcement.*

  1. Reboot your PC and press the F8 key before Windows loads to enter the “Advanced Boot Options” menu.
  2. From the “Advanced Boot Options” menu, select “Disable Driver Signature Enforcement,” and press Enter.

Note: You must disable driver signature enforcement each time you reboot your PC.

Install the Drivers

  1. Once Windows has finished loading, plug your DI-720/730 series instrument into an available USB port.
  2. With the DI-720/730 connected, navigate to the Windows Device Manager (Start>>Computer>>Device Manager). You'll find the unit listed under “Other Devices” as an “Unknown Device.”
  3. Right-click on the “Unknown Device” and choose “Update Driver Software…”
  4. Choose “Browse my Computer for driver software.” Navigate to the location of the driver and click “Next.”
  5. When notified that “Windows can't verify the publisher of this driver software,” choose “Install this driver software anyway.”
  6. With the driver properly installed, your DI-720/730 series instrument will appear in the Windows Device Manager under “Universal Serial Bus controllers.”

Once the USB drivers are installed, you can install WinDaq Software.

Applies To

DI-720, DI-722, and DI-730 series USB products using 64-bit Windows Vista and 64-bit Windows 7.

* Disabling driver signature enforcement is a temporary measure that will no longer be necessary once the DI-720/730 USB driver is digitally signed by Microsoft. We are currently in the process of getting the driver signed.

DATAQ ActiveX Controls allow users to write custom software to interface with DATAQ Instruments Hardware Devices. DATAQ ActiveX Controls are free to use, and install automatically when WinDaq Acquisition Software is installed.

Please Note: High sample rates (over 150K) may not be achievable using the ActiveX Controls.

Please Note: The ActiveX Controls DO NOT support synchronous data acquisition for the DI-720/722/730/740/785/788 Ethernet products, DI-1100, or DI-1110.

DATAQ Instruments ActiveX Controls Frequently Asked Questions

  1. What are DATAQ ActiveX Controls?
    The ActiveX control standard defined by Microsoft describes modular, reusable software components that can be used universally by any environment that supports the standard. For example, without modification, the same controls may be used by Visual BASIC, Visual C++, National Instruments LabVIEW, CEC TestPoint, Borland C++ Builder, Excel and many more. Click here to learn more.
  2. How do I install the DATAQ ActiveX Controls?
    Click here to download the ActiveX Control Library FREE
    The ActiveX Control Library installs automatically when you install the software for your DATAQ product from the WinDaq Resource CD. Please click on the above link if you want to install the most recent version of the ActiveX Control Library. The latest update is necessary for compatibility with our new products (DI-158 series, DI-710 series, DI-148U).
    Click here to learn more about the DATAQ ActiveX Control Library.
  3. How do I use my specific DATAQ device with ActiveX / What are my DEVICE ID and DEVICE DRIVER?
    The DataqSdk component works with all DATAQ products. To use the DataqSdk control with your product, you must figure out the DeviceDriver and DeviceID for your hardware.
    Click here to get the latest ActiveX installation.
    DeviceDriver and DeviceID can be deduced from the ActiveX Controls Help file (dataqxc.chm) and they can also be found in the tpdataq.ini file located in your Windows directory. If DeviceDriver and DeviceID are not set, the same values are used as the last time WinDaq was started, which are saved to C:WINDOWSTPDATAQ.INI [Global] section in keys DLLName = and DeviceID=.
    DeviceDriver is the DLL to be used with the corresponding device, available in the tpdataq.ini file.
    DeviceID represents a connection method to the device.

    1The DI-145, DI-148U, DI-158U/UP, and DI-71x USB versions all use a virtual COM port. Some products use a virtual COM port even though they may have an alternate interface connection (like USB). Such products use the serial port device driver and ID. See Question 4 below 'What COM port is my device connected to?'

    2The Device ID consists of a 32-bit value comprised of the COM port number, two digits representing the device model number, and the Baud Rate.

    3The COM port number is specified during installation of the device. COM port numbers of 01 to 99 are supported. Example: For a Serial device installed to COM 1 the DeviceDriver=DI101NT.DLL. See Question 4 below 'What COM port is my device connected to?' for instructions on finding the correct COM port.

    4Virtual Device # can be found in c:Windows pdataq.ini, or at the end of the WinDaq installation.

    5The order of WinDaq/IP installation - look in title bar of WinDaq Acquisition when running device or check your installation directory for file(s) named WDQDK6nn.EXE. nn = 0 to 39 RESERVED; nn = 40 to 69 for DI-710E and DI-715BE devices; 70 to 99 for DI-718BE and DI-718BxE devices.

    6The order of WinDaq/IP installation - look in title bar of WinDaq Acquisition when running device or check your installation directory for file(s) named WDQDK8nn.EXE. nn = 0 to 59.

    7Starting WinDaq acquisition with V3.89 or later sets DLLName= and DeviceID= in the TPDATAQ.INI [Global] section, which become the default DeviceDriver and DeviceID if not set by a program using WinDaq.ocx or DataqSdk.ocx.

    8A null string or '00000000' opens the first available connected device found.


    Download and see the ActiveX help file for more information.
  4. What COM port is my device connected to?
    STEP 1: Open the Windows Device Manager. The Windows Device manager can generally be found by holding the Windows key down then pressing the Pause/Break key on your Windows keyboard to access the System Properties window. From there, the Device Manager should be accessible but may require an extra click or two (for example, in XP, click on the Hardware tab then on the Device Manager button).
    STEP 2: Find Ports (COM & LPT) and expand by clicking the + box to the left. This shows all COM and LPT ports currently assigned on your computer.
    STEP 3: Find DATAQ DIxxx (COM#) - # is the COM port designated for your device.
    STEP 4:Change the COM port Number of your Device.
    a. Right-click on DATAQ DIxxx (COM#).
    b. Click on Properties.
    c. Click on the Port Settings tab.
    d. Click on the Advanced button.
    e. Click the down arrow on the COM Port Number drop-down menu.
    f. Select an alternate COM port number (MUST be COM 16 or lower).
  5. How do I troubleshoot my ActiveX project? Note: this debug procedure is the first step if you need technical help with your program.
    A log file (DATAQSDK.LOG) may be created in the directory from which your program runs every time you run the DataqSDK control. This tool helps DATAQ Technical Support to debug your program if errors occur and you cannot figure out the problem.
    STEP 1: To enable creation of this log file add the line 'debug=1' to the [Global] section of the TPDATAQ.INI file under your Windows directory at C:WindowsTPDATAQ.INI file
    [Global]
    debug=1
    STEP 2: Depending on the system setup of the target PC, DATAQSDK.LOG may be located in a different directory, the best way is to do a search on your PC.
    Note: The log file is cleared each time the DataqSDK control is loaded. In VB when an error occurs do not stop the program - the program must still be running to access the log file (i.e., stay in 'debug' mode). For help with your program make sure you copy and email the log file before closing your application.
    By using this log file Technical Support can significantly reduce response time to your problem.
    Examine the following for a typical log file format:
