Appendix D Troubleshooting

SYMPTOM: The Configuration Utility is not working properly
(e.g., I cannot read the settings from the CSA) and/or I get an
error message that says "Unable to open the COM port."
POSSIBLE REASONS
The CSA is not attached properly to
your computer.
The CSA does not have power. The
LED is not blinking.
The CSA currently is configured with
automatic connections and DTR
disabled, and the remote device is
within range. Thus, you are currently
connected to the remote device.
ActiveSync has control of the port
where the CSA is attached.
Your computer is already connected to
another device using the same COM
port that the CSA is trying to access.
SYMPTOM: The CSA is not communicating properly with my
third party software.
POSSIBLE REASONS
You configured the CSA and/or the
third party software incorrectly.
You are using auto-detect and Plug
and Play functions.
Various possible reasons, such as
incompatible hardware.

SOLUTION
Properly insert the CSA, pushing it into
your computer's serial port as far as it will
go.
Use the AC adapter to connect the CSA to
an electrical outlet.
Remove the remote target from range.
In the ActiveSync connection settings,
make sure a serial cable connection is not
allowed at the COM port where you
attached the CSA.
Disable the conflicting connection.
SOLUTION
Make sure the CSA and third party
software are set for the same baud rate and
other settings.
Auto-detect and Plug and Play functions
do not work reliably with Bluetooth. Make
sure you manually enter the baud rate and
other settings to match those of your local
host device's serial port.
If your hardware responds to standard AT
commands, set up a test connection with
Windows Hyper Terminal using the CSA
COM port as the connecting modem.
