Keyboard Navigation
Press the TAB key to select each GUI control. The
selected control is indicated by a dotted outline. Using
SHIFT+TAB moves the selection to the previously
selected control. Buttons respond to the keyboard’s
SPACE bar. Some controls respond to the keyboard
UP and DOWN arrow keys. Activate the program ’s
menu bar by pressing the F10 key, and then press the
letter of the desired menu item. Most menu items have
one letter underlined, indicating their shortcut key.
General Troubleshooting
Problem: Software reports it cannot find the inter-
face circuit.
? Is the interface circuit power LED lit?
? Is the USB cable connected?
? Has Windows plug-and-play detected the board?
Bring up Control Panel-->System-->Device Manager
and look at what device nodes are indicated for USB.
If there is an “unknown device” node attached to the
USB, delete it (this forces plug-and-play to try again).
? Are jumpers JU1–JU4 properly configured for USB
operation?
