2.1 USB Driver Installation
This EV kit includes an isolated USB interface for serial communications with a PC. The FTDI USB controller
IC FT2232 performs the USB functions. The FTDI Windows driver presents a virtual COM port for enabling
serial communications. The FTDI Windows driver is a certified driver for Windows XP and Windows 7.
Upon attaching the MAX78630+PPM EV board to the PC, the Found New Hardware Wizard automatically
launches and installs the appropriate driver files. If your PC does not find the FTDI driver files on its local hard
disk drive, locate and reference the FTDI USB Driver and Utilities subdirectory on the CD. The FT2232
controller is powered from the USB cable and is active even when no AC power is applied to the
MAX78630+PPM EV kit.
Note: If an older FTDI driver has been previously installed, it is recommended to remove the older version
before installing this newer FTDI driver. Execute the ftdiClean.exe utility from the FTDI USB Driver and
Utilities subdirectory.
For FTDI driver support on other operating systems, refer to the FTDI website at www.ftdichip.com.
2.1.1 Confirm COM Port Mapping
• Launch the Control Panel and click on the System icon.
• The System Properties screen appears. Click on the Hardware tab. Click on Device Manager. Under
Ports (COM & LPT), look for the USB Serial Port assignment.
• Take note of the COM port assignment for the USB Serial Port.
2.1.2 FTDI COM Port Trouble Shooting
If the FTDI device driver did not install properly, there would be no assigned COM port number for the FTDI
controller. Repeat the USB Driver Installation, see Section 2.1.
Microsoft Windows may associate a Ball Point device to the FTDI USB controller. When this occurs a FTDI
device COM port assignment is available via HyperTerminal but there is no communications data. Verify if a
Ball Point device has been added to the “Human Interface Devices” via the Device manager. See Section 2.1.1
for access to the Device Manager. If a Ball Point device exists, delete it and unplug and replug the EV kit’s
USB cable.
Two sequential COM
ports are associated
with the kit. Use the
second COM port
Port numbers may
differ on each PC.
