Troubleshooting

PLEASE READ

If you are have any trouble at all, please uninstall both the drivers (see above) and the PCLab software, go to the website and download the latest driver and PCLab version and follow the installation instructions. If you continue to have issues, see below.

Surface Pro 3

There is some indication that the single USB port on the Surface Pro 3 does not interact properly with the scope, causing the PcLab2000 software to hang after running a single function. Using a USB hub (powered or unpowered) seems to resolve this issue.

Program is running, cannot see window

This happens if you plug your laptop onto a second monitor, have the PcLab2000 program open on the external monitor, and then unplug the monitor. The PcLab program window can get stuck on the now non-existent monitor space.

To bring it back into view, do this:

  1. First make sure you’ve alt-tabbed to the window, or clicked on it once to bring it into focus.
  2. Then right-click on the taskbar and choose Move
  3. At this point, you should notice that your cursor changes to the “Move” cursor, but you still can’t move anything.
  4. Just hit any one of the arrow keys (Left, Right, Down, Up), move your mouse, and the window should magically “pop” back onto the screen.

You can also do this via keyboard shortcuts:

  1. Alt-tab to the PcLab program window
  2. Hit Alt+Space
  3. Hit M
  4. Hold down an Arrow key, and then move your mouse, the window should pop back in place.

Other pcsgu250 software may be active

If you get an error starting with "Other pcsgu250 software may be active..." and the PcLab2000LT program is hanging, do the following:

  • Open Windows Task Manager (CTRL-SHIFT-ESC) and kill the hung PcLab2000LT process
  • Open Windows Explorer (Computer)
  • In the toolbar select Organize -> Folder and search options
  • In the View tab, select "Show hidden files, folders and drives", click OK
  • Locate the folder: C:\Users\<your username>\AppData\Local\Velleman\
  • Delete the entire Velleman folder

The PcLab2000LT program should now be functioning.

Matlab Plugin Issues

  • ECE students that will be using the Velleman scope integration will require 32-bit MATLAB installations (due to the library provided by the vendor is 32-bit only). The documentation in the support package does call out this requirement.
  • 64-bit OS users can have both a Win 32-bit install and a win 64-bit install at the same time (as well as for different versions e.g. R2011a and R2011b). There may not be a reason too, but it is possible. Each of these installations go into a different installation folder, and the applications can be run at the same time if desired.
  • Matlab will give an error if the path to the plugin contains the @ symbol. Try and keep your folder names simple and don't use special characters.

Bode Plot Hangs

  • Drivers from Velleman have been updated, this might not be an issue anymore.

When running on a 64-bit machine, you must install the PCSGU250Driver_WinUSB driver, not the PCSGU250Driver. If you have accidentally installed the PCSGU250Driver, follow the directions for uninstalling and installing drivers
