Appendix A
Communicating with the
KC705 USB-UART
This appendix explains the procedure for setting up UART communication between the
KC705 board and the host machine.
Installing the USB-UART Driver
1. Execute the installer for the Silicon Labs USB-UART virtual COM port (VCP) driver
from the Drivers_and_Tools folder in the package downloaded from the
embedded kit home page:
Drivers_and_Tools\CP210x_VCP_Win2K_XP_S2K3.exe.
2. Follow the installer instructions. Restart the computer when instructed to do so.
Connecting to the KC705 UART
3. Connect a USB Type-A to Mini-B 5-pin cable between the KC705 USB-UART connector
(J21) and the host computer.
4. Power on the KC705 evaluation board if it is not already powered on.
Configuring the Host Computer
5. Right-click on My Computer and select Properties. Select the Hardware tab. Click on
Device Manager.
6. Expand the Ports (COM & LPT) entry as shown in Figure A-1. This shows the COM
port assigned to the Silicon Labs CP210x USB to UART Bridge. This is the COM
port to use in the serial communications program.
Note:
The COM port setting for the user system might be different from the one shown in
Figure A-1.
