written in C and C++ and includes the use of the MFC (Microsoft Foundation Classes)
library included with Microsoft Visual C++ (or Studio) Version 6.0. The USBTest program
also makes use of a library called FTDIXXX .DLL that is freely available from FTDI, the
manufacturer of the USB chip set used in the Lambda 10-3 and which gets installed on your
system when the USB device driver for the Lambda 10-3 is installed. The FTDIXXX .DLL is
“bound” to the USBTest program via two files that are included with the USBTest program
source code: FTDIXXX.H, a C/C++ header file that gets included at compile time, and
FTDIXXX.LIB, the FTDIXXX.DLL interface library file, which gets linked to the project at
link time. All three files are freely downloadable from FTDI’s web site: (
www.ftdichip.com ).
Alternatively, a custom program can be written to verify the installation and for sending
commands to the Lambda 10-3. Although providing the source code for an entire ready-to-
run program is beyond the scope of this manual, the following paragraphs describe the key
elements such a custom program should have in order to identify, connect with, and transmit
to the Lambda 10-3 as a USB device. Accompanying these paragraphs are listings containing
snippets of code written in the C programming language that may prove of further use
should it be desired to create a custom program. Note that the code examples assume that
the FTDIXXX.LIB and FTDIXXX.H files described previously are being used. You may
download these files directly from FTDI’s web site:

Normally, the device drivers installed on your system that enable communications with the
Lambda 10-3 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 10-3 (e.g., the Lambda
10-3 will no longer be used with the system in question), the following steps can be followed
for Windows 98, ME, 2000, or XP.
1. Open the
Control Panel
(click on
Start
to bring up the main Windows menu, then click on
Settings , and then Control Panel in the submenu).
2. Within the Control Panel window, double click Add/Remove Programs . A new window is
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 10-3, 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 completed, the FTD2XX entry in the Add/Remove list should now
be gone.
Note that although the above procedure will remove the Lambda 10-3 USB device driver
from active use, not all related files on your system are actually deleted. Should you decide to
reinstall the USB driver for the Lambda 10-3 after having gone through the uninstall
process, Windows will most likely be able to locate the necessary USB driver file on your
