1.6. How to switch between Standard and OEM drivers
The USB-3000™ incorporates a USB to serial UART Integrated Circuit Device manufactured by FTDI (P/N
FT232R). DVSI has modified the generic FTDI drivers so that the USB-3000™ uses a virtual COM port on the
PC to provide access to the USB-3000™. The USB-3000™ requires that two drivers be installed, the Virtual
COM Port (VCP) driver and the USB Serial Port driver. The application software provided with the USB-3000™
requires the installation of these two drivers. Refer to the USB-3000™ User Manual for the driver installation
procedure.
USB-3000™ users can choose DVSI supplied drivers to incorporate into their application or utilize FTDI’s D2XX
drivers or other off-the-shelf drivers for even more customization flexibility. The D2XX drivers allow direct
access to FTDI FT232R USB to serial UART device through a series of DLL function calls. Using this method
there is no need to set up a virtual COM port.
However, in order to be able to utilize the FTDI generic D2XX drivers the USB-3000™ -OEM version must be
purchased. If you already have the standard version (non OEM) USB-3000™ it must be reprogrammed to the
default FTDI product ID (PID) before it can operate with the D2XX drivers.
To reprogram the PID in a USB-3000™ in order to operate with the D2XX drivers the user must follow the
procedure below.
Step 1. Install the DVSI drivers provided with the USB-3000™. Refer to the USB-3000™ User Manual for the
driver installation procedure.
Step 2. Connect the USB-3000™ to the PC.
Step 3. Download a utility program (FT_PROG.exe) from the FTDI website
http://www.ftdichip.com/resources/utilities.htm
Note:
The FT_PROG requires Microsoft .NET Framework 2.0 to be installed on your
system in order to run. If this is not already installed it can be obtained from
Microsoft’s website:

After downloading follow the installation wizard for.NET 2.0.
Step 4. Run the programming utility by double clicking on the FT_PROG.exe icon. The FT Program will open in
an idle mode with the following screen.
