Troubleshooting
Below is a list of problems that may be encountered, and steps to remedy them. If your particular issue is not addressed by the below, see the
Support page on http://eagletreesystems.com or email support@eagletreesystems.com. Include a full description of your problem, your machine
configuration, brands/models of equipment, and Recorder firmware version if possible (from “Tools, Firmware Control” in the app) and any other
relevant details.
Problem: The GPS Module does not appear to be getting a signal. When I download data or look at the data on the Seagull, the data consist of
zeros.
Solution: Make sure you have the Expander connected correctly to the recorder.
Solution: If you are trying to record GPS data, make sure you have selected logging of GPS data as described in the setup section above.
Solution: If you are using the Seagull system, and are not getting “No Signal” messages, see the Seagull manual. If you are getting a signal, but no
GPS data, try the above steps.
Solution: Make sure that the Seagull Expander has a reasonably unobstructed view of the sky.
Problem: The Dashboard displays “No GPS Detected” on the GPS Status LCD Page.
Solution: Make sure you have the GPS Expander connected correctly to the recorder, and make sure that no wires are cut.
Solution: Power down the system, wait 15 seconds, and reapply power.
Problem: The Dashboard displays “Acquiring Fix” on the Lat/Lon LCD Page for more than two minutes.
Solution: Make sure that the Seagull Expander has a reasonably unobstructed view of the sky.
Solution: Make sure you have gotten a valid fix before the vehicle starts moving. Moving slows down the acquisition process considerably.
Solution: Some areas have lots of RF Noise, which can increase the length of time required to get a fix. Up to 15 minutes may be required to get a
cold fix in some areas. Note that we have found that other brands of GPS receivers have the same difficulties in problem areas.
