Chapter 5. Troubleshooting
If you are having problems with your
RK2
, please read these
troubleshooting tips before contacting technical support.
If you continue to have problems, see Chapter 6 for more
information on contacting RTI technical support.
DISPLAY IS DIM, BLANK OR UNREADABLE
Make sure the external power supply is properly secured to the
RK2
, and it is functioning properly.
Try adjusting the contrast level from the
Control Panel
page
(Refer to Chapter 3 for more details).
By nature, the contrast of an LCD screen changes with
temperature, so if the display is cold it will appear dark and will
return to normal as it warms.
USB COMMUNICATION PROBLEMS
Verify that your PC is running Windows
®
98SE or higher.
Verify that the
RK2
is present in the Human Interface Devices
section of the Device Manager within the Windows
®
Control
Panel.
Make sure you are using the programming cable that was
supplied by RTI and that both ends are connected securely.
Make sure the PC detects the presence of the
RK2
. If it doesn’t,
unplug the USB cable, wait for about ten seconds, and plug it in
again.
If the download fails after some data has been transferred, try re-
sending the program.
