5. Troubleshooting
This section identifies potential problems that you may encounter while establishing
communications with the Shark.
1. I cannot locate the Shark using my Bluetooth
®
wireless enabled computer or PDA
to search for Bluetooth
®
wireless enabled devices.
• Make sure that the Shark’s switch in the on position.
• The Shark’s internal battery may be low and, therefore, you will have to
connect external power to the Shark.
• Many computers, PDAs or other Bluetooth
®
wireless enabled devices have
configuration programs that are designed and configured differently. You
may need to consult the manual for that device.
• Your Shark may be too far away from the computer, PDA or equipment
you are trying to establish a Bluetooth
®
wireless technology
communications link with. See section 4.7 The Shark Range and Antenna
Selection.
• A metal enclosure or an object nearby that could attenuate the RF signal
makes transmission difficult and can reduce the range significantly. In
this case, it is necessary to use an external antenna/cable assembly to bring
the signal out to get the range back to an acceptable distance. See section
6.4.4. Antennas.
• Check to make sure The Shark’s antenna connection is good and has not
been damaged.
2. I have located the Shark using my Bluetooth
®
wireless enabled device, but cannot
connect. That is, the blue LED indicator light on the Shark does not display solid
blue.
• Ensure that your Shark is powered properly and the blue LED indicator is
flashing rather than off.
• If your Shark’s blue LED is not flashing, then it may be configured as a
master instead of as a slave. Be sure it is set up as a slave. See section
3.3.2 The Shark Settings.
• If the device is another Bluetooth
®
wireless device, please consult the
manual for that device to verify the recommended connection procedures.
3. I have located and connected to the Shark, but the remote device that the Shark is
connected to does not respond to the commands/information I send.
• Your Shark may not be configured to use the same serial settings (e.g.
baud rate) as the equipment you are connected to. See section 4.5 Baud
Rate.
• Flow Control (also called hardware handshaking) needs to be set the same
between The Shark and the equipment it is connected to.
• The connection between The Shark and the instrument that The Shark is
connected to may be loose. Be sure to properly seat the Shark’s serial
connector to your equipment.
