FTDI USB-to-UART Driver Installation
An FTDI USB-to-UART driver is required to allow your PC to communicate through its
USB port to the on-chip UART of the Z51F3221 MCU. Observe the following procedure to
perform these connections.
1. Ensure that the USB cable is not plugged in to the Z51F3221 Development Board’s P1
connector.
2. Navigate to the following filepath and double-click the CDM20802_setup.exe file to
begin the driver installation.
\Z8051_\device drivers\FTDI Uart
3. The installation process will begin and you should observe output similar to the fol-
lowing messages on the screen of your PC:
32-bit OS detected
\dpinstx86.exe
Installation driver
FTDI CDM driver installation process completed.

The above message may appear for a short time, but will then disappear from your window.
This occurrence is normal.
4. When the installation is complete, plug in the Mini-B connector of the second USB
cable into the Board, and the larger A connector into the USB port of your PC. Refer
to
Figure 15 on page 19 for guidance.
5. If the driver installation was successful, the Ports (COM & LPT) section of the Device
Manager will display USB Serial Port (COMx) or similar message, as highlighted in
Figure 12.
