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
