July 2005 MAX II Development Kit Getting Started User Guide
Getting Started
Using the USB Reference Design
1. Program the board with the USBReferenceDesign.pof file. (Refer to
“Programming the MAX II Device” on page 2–4 for details on how
to load POF files into the MAX II device.)
2. To install the drivers, perform the following steps:
a. When you plug the board into your PC, the message “Found
New Hardware” appears. When that occurs, open your Control
Panel and then open the System Menu. Click the Hardware tab
and then click the Device Manager. In the Device Manager
window look for an item called Other Devices between
Network Adapters and Ports (COM & LPT). If you see Other
Devices, then you must install the drivers. Proceed to Step b.
If you don’t see Other Devices, then expand the Ports (COM &
LPT) item and look for USB Serial Port (COM X), where X is an
integer. If you see the USB Serial Port, then the XP found the
drivers and installed them. Proceed to Step 3.
b. In the Device Manager window, expand the Other Devices
item. Right click on USB <- -> Serial and click Update Driver.
This will launch the Found New Hardware Wizard. In the
Wizard menu select Install from a list or specific location and
click Next.
c. Select Don’t Search. I will choose the driver to install. Click
Next.
d. Leave Show All Devices highlighted and click Next.
e. Click Have Disk.
f. Click Browse and browse to the <root>\Examples\HW
\ReferenceDesigns\USB_ReferenceDesign\Win98_2k_XP_
Drivers directory. Click Open. This will return you to the
Install From Disk menu. Click OK and then select Next in the
Wizard menu. Driver installation should then complete. Click
Finish and note that the COM (Ports & LPT) item in the Device
Manager window now contains an item called USB Serial Port
(COM X), where X is an integer number. You will need to know
the value of X, so make a note of it.
3. Start the USB_Utility.exe application located in the
<root>/Examples/HW/ReferenceDesigns/USB_ReferenceDesign/
Software directory. The user interface shown in Figure 2–6 should
appear.

4. On the Control Options menu select the appropriate COM port for
your system. To find the correct COM port, Browse to the Windows
Device Manager (Control Panel > System > Hardware tab > Device
Manager Button). Expand the Ports (COM & LPT) item and you
should see the USB Serial Port (COM<number>). In Figure 2–7 the
board has been assigned COM4. This port number will be different
on each machine.
After you find which COM port your machine has assigned the
MAX II board, select that port in the Current COM Port drop down
box in the MAX II USB Utility user interface (see Figure 2–6). Click
Open Port. The application tries to communicate with the board. If
successful communication is established, the status box on the
application reports Found MAX II Board on port X (where X is the
number of the port). If it was unsuccessful, the status box reports
Could not find MAX II Board.

5. If successful communication is established, the LCD displays
Connected to PC!.
6. The PC Application allows you to read from and write to most of
the components on the MAX II board. Note the Default Encoding
drop down box in the Control Options section of the user interface.
This controls how the MAX II device interprets the data sent to and
received from the MAX II board. If you select Hexadecimal, the PC
will treat all data as hexadecimal characters. If you select ASCII,
then the PC will interpret all data as ASCII.
1 This demo relies on the appropriate transmission of data
from the PC to the board. If corrupt data is transmitted,
errors will occur. The application on the PC may be
unaware of hardware errors. The board will show hardware
errors by flashing the LEDs. If you see that the LEDs are
flashing, click the Close Port button on the PC application
and press S1 on the development board. You can then
re-open the port and use the demo as normal.
