9 Troubleshooting
Due to many PC environments, the interoperability can be limited. The CMA3000 DEMO KIT has
been tested with DELL laptops (Latitude D600, D610, D410) and desktop PCs with Win2000 and
WinXP operating system. If the CMA3000 DEMO KIT does not work properly or its operation is
limited, the following items may help to sort the problems out:
1. Stop the GUI software, press the reset button program on demo USB interface board (see
Figure 1), re-start the GUI again.
2. CMA3000 demo may not work properly if your PC has multiple USB serial port devices
installed. Please remove all other USB serial port devices (including other VTI demos).
3. Close
Windows
HyperTerminal
software, if you have used it.
4. If the GUI interface starts, but data is not scrolling in the window, check that USB driver
LATENCY TIMER parameter is 5ms, please see details in section 9.1
5. Some times other LabView based software do not allow the demo kit GUI software
execution, please try to install the CMA3000 demo kit to another PC or remove other
LabView based software
6. If the PC is unable to find the demo kit serial port, try another USB port. Also, please check
that there are not duplicate serial COM port numbers, more details in section 9.2.
7. The CMA3000 demo kit GUI does not support Windows Vista
8. Test the demo with another USB cable.
9. Please check that does the communication work between the demo kit and the PC:
•
Open HyperTerminal connection to the demo (see section 5)
•
Press demo reset button (see Figure 1)
•
see if the info text appears on the screen (see Figure 12)
