EEPROM WRITE UTILITY
The DLP-245PL-G has the option to accept manufacturer-specific information that is written into
the on-chip EEPROM. Parameters that can be programmed include the VID and the PID
identifiers, the manufacturer's product string, and a serial number.
MPROG is the latest EEPROM serializer utility from FTDI for the FT245RL device. MPROG is
based on the new D2XX drivers and will work on Windows 98, Windows ME, and Windows
2000/XP platforms. You must install the latest release of the D2XX drivers in order to run this
application.
If you have VCP drivers installed on the PC that will be used to perform the EEPROM write
process, you must uninstall these drivers and install the D2XX drivers prior to running MPROG.
QUICK START GUIDE
This guide requires the use of a Windows 98/2000/XP PC that is equipped with a USB port.
1. Download the DLL version of the device drivers from either dlpdesign.com or ftdichip.com.
2. The DLP-245PL-G can be configured to receive its operating power from the USB port or
3. Jumper JP2 selects the power source for the 18LF8722 microcontroller and the interface pins
4. Connect the DLP-245PL-G board to the PC via a standard A-B, 6-foot USB cable. This
The DLP-245PL-G is shipped with default VID, PID, etc. values programmed into the EEPROM.
You only need to run MPROG if you want to change the default values.
At this point, the DLP-245PL-G is ready for use. Note that the DLP-245PL-G will appear
non-responsive if data sent from the host PC is not read from the FT245RL device by the
18LF8722 microcontroller.
If changing drivers from the VCP to the DLL type (or vice versa), you must first uninstall the
currently loaded drivers. This is accomplished by first disconnecting the DLP-245PL-G adapter
from the host computer and then running Add-Remove-Programs (via Control Panel) to remove
the currently loaded drivers.
Unzip the drivers onto a blank floppy disk or into a folder on the hard drive.
from an external power source. Jumper JP1 allows for this configuration. Select JP1 Pins 1
and 2 if the DLP-245PL-G is to take its power from the USB port on the host computer;
jumper JP1 Pins 2 and 3 if the DLP-245PL-G is to take its power from your external power
source.
on the FT245RL USB chip. Select JP2 Pins 1 and 2 if 5 volts from the USB port is to be used
to power the microcontroller. Select JP2 Pins 2 and 3 if an external supply is to be used to
power the microcontroller.
Note: The board will not operate until a power source has been selected as mentioned in
Steps 2 and 3.
action initiates the loading of the USB drivers. When prompted, select the folder where the
DLL version of the device drivers was stored in Step 1. Windows will then complete the
installation of the device drivers for the DLP-245PL-G board. The next time the DLP-245PL-
G board is attached, the host PC will immediately load the correct drivers without any
prompting. Reboot the PC if prompted to do so.
