Appendix A - PCB EEPROM Configuration
Each USB-RS232-PCB is controlled by the FTDI FT232R IC. This FT232R device contains an EEPROM which
contains the USB configuration descriptors for that device. When the PCB is plugged into a PC or a USB
reset is performed, the PC will read these descriptors. The default values stored into the internal EEPROM
are defined in Table 0.1 Default Internal EEPROM Configuration

Table 0.1 Default Internal EEPROM Configuration
The internal EEPROM on the PCB can be re-programmed over USB using the utility program MPROG.
MPROG can be downloaded from the www.ftdichip.com. Version 2.8a or later is required for the FT232R
chip. Users who do not have their own USB Vendor ID but who would like to use a unique Product ID in
their design can apply to FTDI for a free block of unique PIDs. Contact FTDI support for this service.
