DigiLite

On the FTDI webpage,scroll down the FTDI page, select the Windows row from the table 'Currently Supported VCP Drivers: 'at the bottom half of the page. Click on Available as setup executable. Connect the usb cable to the FT mini-module on the serialiser board (no dc required) then run the install software. (CDM20814.exe) If install asks for a floppy drive disk just change the drive letter and point to your downloaded file. Download and run the FTProgv2.2 to flash the EEprom on the panel.(You need to have .NET 3.5 on your pc to run it though). Load the FT2232HQ_DATV_template into the FTProg and program the FTmodule with it. See sub page 3 for detailed instructions.

An outline of the DigiLite Software Design and Functioning..................by its author: Brian G4EWJ
Recording program
GBPVR is a free PVR (personal video recorder) program. Versions up to 1.4.7 have been used successfully. The later version called NextPVR is not suitable. GBPVR requires a certain standard of video graphics card to run, even if you do not actually want to watch the video on that PC. Older graphics card may have problems.There is a setup help page on SOFTWARE sub-page 2.
If the file has a .ts tag instead of .mpg you must change settings as you will not get the DigiLite software to use it.
Conversion program
DigiLite Transmit is the program that reads the recorded data from hard disk immediately it has been written. The data is in Program Stream format, which is very similar to the format used on DVDs. The video and audio are extracted and converted into DVB-S transport stream format, which is the format used by European broadcasters to deliver standard definition programs via satellite. This means that a cheap FTA (free to air) satellite box may be used to receive the transmission. Other data is placed in the transport stream such as date and time, channel name, program name and EPG info. The transport stream data is sent to the serialiser via a USB port.
Configuration
Config is the program that is used to set the symbol rate and FEC and also the channel name and program details. Settings are stored in the Windows registry, which DigiLite Transmit monitors continually to look for any changes in transmission parameters.
Serialiser
This is the device that connects to a high speed (480Mbps) USB 2.0 port and accepts the transport stream data from the PC. . Doing the FEC on the serialiser reduces the data rate over the USB connection.The serialiser has a second communication channel which is used to receive control information from DigiLite Transmit to set the required symbol rate and FEC. The serialiser has been used successfully at symbol rates between 1250k and 6250k. Several symbol rates are pre-programmed into the system. The serialiser board has for an optional SD card socket for playing pre-recorded transport stream files. This function is still in development and is not available in the initial release. For updates and changes see the M0DTS website.
Modulator
This must be provided with a signal source at the required transmission frequency. It filters the two digital signals (I and Q) from the serialiser and produces an output at the transmission frequency which can then be amplified and transmitted.Most local oscillators deisgned to use with digital signals will work,but levels may need to be attenuated by up to 20dB . There is a 3 resistor pi attenuator at the input of the modulator board.
