Windows Software Operation
A 32-bit Windows application that performs the firmware download process is available as a free
download from dlpdesign.com. The application uses the DLL version of the device drivers.
The HELP button can be clicked at any time to read a description of each control.
This download application uses the “OpenEx” function that allows multiple DLP-IOx boards to
be connected to the same PC in a well-organized manner.
This function will open the named device and return a handle that will be used for subsequent
accesses. When the Search button is clicked, a dialog window is opened and all FTDI devices
connected to the system are listed for easy selection. The device name can be its serial number or
a device description; both are text strings that are programmed into an EEPROM that is directly
connected to the FT8U245AM. A third method, open by device number, can be used for new
boards that have not had a serial number or description string written to the non-volatile RAM.
