A PASPort interface is undetected on a Mac

Affected Products:

PS-2100A USB Link
PS-2002 Xplorer GLX

A PASPort interface is undetected by DataStudio, SPARKvue or PASCO Capstone on a Mac

PASCO Solution:
  1. Check that your computer has a supported operating system installed:
    • PASCO Capstone (1.2.1): MacOS 10.7+
    • SPARKvue (1.3.0): MacOS 10.7 +
    • DataStudio ( MacOS 10.2 -10.7
  2. Check that you have the latest version of the data acquisition software installed.
  3. Check that you are logged into the Mac as an administrator.
    1. Launch System Preferences by clicking its icon in the Dock.
    2. Click the Accounts icon.
    3. Check if "My Account" has "Admin" appear beneath it.
    4. Click OK.
  4. Unplug all USB devices from the computer.
  5. Disconnect any PASPort sensors that may be attached to the interface.
  6. If you are using a PS-2002 Xplorer GLX or PS-2008 SPARK SLS, check that the interface is turned on and that you are connecting to the smaller (mini-B) USB port on the PASPort interface, via a PS-2528 Xplorer GLX - USB Cable or other USB-A to USB-Mini-B cable.
  7. Plug the PASPort interface securely into a USB port other than the the keyboard port which may not provide enough power.
    1. Avoid the use of the PS-2500 PASPORT Extension Cable with any sensors that already have a cable attached.
  8. Check that the MacOS detects the device:
    1. Click on the Mac icon in the upper left corner of your screen.
    2. Select About this Mac/More Info....
    3. From the Hardware/Contents column on the left, select USB.
    4. Look for your PASPort interface in the list of devices.
    5. If the interface does not appear, connect the interface to another USB port and press Command + R to refresh the list.
    6. If the interface still does not appear and you are using an XPlorer GLX or SPARKlink, turn the device off and back on. Wait until the device has completely started and press Command + R to refresh the list.
    7. If the interface does not appear in the list when connected to any of the available USB port, check the sensor with a system that is known to work with another PASPort interface.
    8. If the interface fails with that system as well, contact PASCO Teacher Support with the serial number of the interface to have the interface repaired/replaced.
  9. Run your PASCO data acquisition software.
  10. If you are running DataStudio, check that you have set it up to detect a PASPort interface:
    1. Open DataStudio and select Create Experiment.
    2. Click on the Setup button, select Choose Interface..., select PASPort, and select OK.
  11. If you still have problems, contact Teacher Support with the version of your operating system and interface part number for additional troubleshooting.

Other version of the MacOS may work, but have not been tested extensively.
