5 Troubleshooting
5.1 No RF signal
• Verify the Antenna is correctly connected to the Module. Verify the
position of the Antenna is in a strong signal location.
5.2 The Module does not answer through the serial link
• No or incorrect power is being supplied to the Module. Verify the Power
Supply and ON/OFF Switch position.
• The Module is not adequately assembled onto the Interface Board.
Verify that proper grounding (ideally solder) is provided.
• The wrong DB-9 connector is being used. Verify that the DATA Port is
connected to the controlling PC.
• The terminal emulator application, HyperTerminal for example, is not
correctly configured for the Module. Verify the Baud rate. It is possible
that the Module has been configured for a different default Baud rate, so
it may be necessary to try different rates in HyperTerminal.
5.3 No audio
• The wrong Audio Path has been selected. Try the other Audio Jack, or
issue the AT Command to verify/select the correct path.
• The SNGL/DIFF Jumper is not correctly installed. This only affects the
Headset Audio Path.
