If you calibrated, the data values displayed for your servos should be as follows:
Rudder, Ailerons, Elevator: -100 to 100; Throttle: 0 to 100 (with negative values for idle trim down)
Using your Seagull in Laptop Live Mode
If you have a laptop at your site, or wish to see live data with your vehicle on the bench, the software can be used to view
the Seagull data parameters live in a “big screen” format, with almost infinite recording capability!
To use Live Mode, first select “Software, Choose Instruments to Display on PC Screen” in the software, and set up the
parameters you want to display. Two Seagull specific items are available to display, as well as the other parameters:
Seagull Signal Strength – this item shows the strength of the real-time signal coming from the Seagull Transmitter.
Seagull Packet Percent – this item shows the percentage of packets that were successfully received from Seagull.
To invoke Live Mode, first ensure that your Dashboard is receiving data from the transmitter. Then, connect the
Dashboard to USB, and click the Live Mode button on the software. NOTE: If you have a 9V battery in the
Dashboard, the Dashboard must be powered on before connecting to USB. A window may display asking you
whether to record the Live Mode data. After choosing this option, Live Mode should start and display the live
parameters.
Note: several of the Live Mode parameters are zeroed when Live Mode is started. Stop and restart Live Mode if the
parameters did not correctly zero.
Note: whenever a packet is missed, the previous packet is duplicated in the Live Mode recording. The duplicated
packets are marked as duplicated in the “error” fields of the recording – these are visible when viewed in Excel. See the
Recorder manual for more information on viewing the files in Excel.
Note: if the 9 volt battery is installed in the Dashboard, the Dashboard will be powered by the battery even when the USB
plug is connected. If you wish to monitor or record very long runs with Live Mode, turn off all power to the Dashboard
and remove the 9 volt battery. Then, the Dashboard will be powered by USB.
Using the Recorder/Data Logger
Please read the important information below on Recorder operation before using it in your model.
The Recorder’s LED
The Recorder’s LED serves several purposes. When the Recorder is powered on when installed in your model, the LED
flashes a number of times to indicate your 4.8 or 6 volt battery’s charge state at power-up time. Five flashes indicates a
fully charged battery, and three or fewer flashes indicates that the battery is likely not safe to use. Loading can affect
these readings, of course.
IMPORTANT: The Recorder’s battery indicator should be used as a guide only: you need to verify that the LED
gives accurate results with your system, and you need to make sure that your battery’s charge state is sufficient
before flying under the appropriate loads.
WARNING: The Recorder gives charge level indication for both 6 volt and 4.8 volt batteries, and attempts to
detect which is installed automatically.
Be aware that if you have installed a 6 volt battery and it goes so dead that it looks like a fully charged 4.8 volt
battery, the Recorder will flash five times
because it thinks the battery is fully charged, though the 6 volt battery is actually nearly dead!!
