Uninstalling The Usb Driver For The Lambda 10-B; Remote Commands And The Usb Interface - Sutter Instrument LAMBDA 10-B Operation Manual

7.6 Uninstalling the USB Driver for the LAMBDA 10-B

Normally, the device drivers installed on your system that enable communications with the
LAMBDA 10-B over the USB, once installed, do not need removing from your system. If you
do need to remove the USB drivers installed specifically for the LAMBDA 10-B (e.g., the
LAMBDA 10-B will no longer be used with the system in question), the following steps can be
followed for Windows.
Control Panel
1. Open the
Settings
, and then
2. Within the Control Panel window, double click
opened in which a list of software that is installed on your system is displayed.
3. Select the line that has "FTD2XX Uninstaller" as the description and click the "Remove"
button towards the right of the description. The FTD2XX Uninstaller program starts and
displays a dialog asking you to disconnect the USB cable if it is still connected.
4. Unplug the USB cable connected to the LAMBDA 10-B, and then click the Continue
button. The uninstall process completes (one more dialog shows up indicating that
registry entries and files are getting deleted). The uninstall process is now complete --
click the Finish button to finish. Alternatively, click Cancel to cancel the whole uninstall
process.
5. If the uninstall process is completed, the FTD2XX entry in the Add/Remove list should
now be gone.
Note that although the above procedure will remove the LAMBDA 10-B USB device driver
from active use, not all related files on your system are deleted. Should you decide to reinstall
the USB driver for the LAMBDA 10-B after having gone through the uninstall process,
Windows will most likely be able to locate the necessary USB driver file on your system
during the installation process, without requiring you to supply the disk containing the
driver.
If you wish to completely remove the USB driver and related files from the system, use either
of the following two methods.
1. Manually delete the file FTD2XX.sys from the "system32" directory in your Windows
directory.
2. Navigate via My Computer or Windows Explorer to the "system32" directory in your
Windows directory, locate the file FTD2XXUN.EXE, and double click on it to launch the
general-purpose FTDI uninstaller program. Running this uninstall program will remove
all pertinent FTDI entries in the Windows registry, a far safer approach to removing the
entries manually.

7.7 Remote Commands and the USB Interface

The same set of commands described in the External Control: Serial Port chapters are
available for use when the LAMBDA 10-B is connected to a computer as a USB device.
