Packing List
Your package should include the following: GPS Expander, and a printed version of this manual. Please check your packaging for printed addenda
to this manual which may be included if changes were made after printing.
How the GPS Expander Works
When coupled The GPS Expander uses satellite information to determine position, speed,
altitude, course, distance to operator, and UTC time.
Connecting the GPS Expander to the Recorder
The 4 wire connector attached to the GPS Expander plugs into the rightmost port of your Data
Recorder as shown in Figure 1. Make sure that you connect it in the correct location on the
recorder, and with the correct polarity!
Installing the GPS Expander in your Model
The GPS Expander should be mounted with Velcro in your vehicle so that the top part (with the label) is facing toward the sky. Normally, it is
satisfactory to have the expander inside the vehicle, since the skin of most vehicles is relatively thin. If you have difficulty getting a signal, try
mounting it externally to the vehicle.
Setting up the GPS Expander with your Recorder
To use the GPS expander, first ensure that you have the latest version of the Windows application (the app). App updates are available as a free
download from the support page of our website, for our customers.
When configured with the recorder, the Expander will record all GPS parameters as listed in the features section above, and the data is also available
on the Seagull Wireless Dashboard.
If you wish to record GPS data, choose “Tools, Choose What To Log” in the app, and select “GPS Parameters”. This indicates to the recorder that
GPS data should be recorded. Note that you DO NOT need to record GPS data to see it live on the Seagull Dashboard.
To configure the app to display the GPS data, choose “Tools, Choose What to Display” in the app, and select the GPS Parameters you wish to see.
Here is a description of the parameters available:

The combination of the Seagull Dashboard and GPS Expander makes it easy to find lost planes. First, make sure you have selected Lat/Lon for
display on the Dashboard.
The Dashboard always remembers the last valid fix received from the GPS Expander, even when no signal is being received from the plane. To
display the last valid fix, press the “Display Max” button on the Dashboard, and scroll to the Lat/Lon page. This will show the last valid fix
received from your plane. To go to that location, use any handheld GPS unit (or another Seagull) to go to that location.
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 [email protected]. 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.
