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 for easy options for getting answers to your questions, 24 hours a day.
Issue: After I power my system, I see the OSD Pro startup screen, but then the OSD turns off, leaving only the video image. And/or, the OSD Pro’s data
only display briefly, and then only the video is shown. Or, the video screen goes black shortly after I turn on the OSD Pro. Or, I see large, rapid
fluctuation in the “Pack Voltage” display parameter.
Solution:
•
Invoke the menus, and confirm that you have the OSD Pro turned on, in the main menu settings.
•
If you are using the eLogger V3 with the OSD Pro, make sure you are using the Battery Backup Cable as described in the “Connecting the OSD Pro to
your eLogger V3” section above.
Issue: I am having trouble getting a GPS fix. Or, once GPS fix is acquired, it is periodically lost, or the GPS values seem to move around quite a bit.
Solutions:
•
If you are using a 900 MHz video transmitter, it is quite probably generating spurious noise on the frequencies used by GPS. A good description of the
causes and solutions of this problem is located here:
http://www.dpcav.com/data_sheets/whitepaper_GPS.pdf . This problem is also reduced by using
our GPS V4 module, which has a pre-wired ferrite choke.
•
If you are using the eLogger V3 with the battery backup cable, and the voltage supplied to the battery backup cable is greater than 5.8V, the GPS
Expander may not work correctly. Reduce the voltage to less than 5.8V.
•
See your GPS Expander manual for other troubleshooting tips.
Issue: I am able to see video and data with my OSD Pro board, but am seeing problems such has “internal error” messages, incorrect data, or random text
display.
Solutions:
•
Upgrade to our latest software, by clicking on the “Support” tab on our website and choosing the “Download Latest Software” option.
•
Run the OSD Pro PC Setup utility by clicking “Hardware, Configure OSD” and click ‘FACTORY RESET.” Then, reconfigure the OSD Pro board.
Issue: The message “OSD Pro Board is not connected. Please connect the OSD and try again.” appears when I try to configure the OSD Pro with the
Windows Software.
Solutions:
•
Ensure that the OSD Pro is connected correctly, with the correct polarity, to the eLogger or Recorder
•
Ensure that the eLogger V3 or Recorder is connected correctly to USB. The LED should flash a sequence of three repeating blinks if it is correctly
connected.
•
Ensure that you have updated the eLogger/recorder firmware and OSD firmware as described in the “Windows Software and Firmware Update” section
above.
Issue: I see only a black screen, the OSD Pro startup screen, or no video image at all, on my video monitor after connecting the OSD Pro between the
camera and the Video Transmitter/DVR.
Solutions:
•
Verify that a correct video image is displayed if you remove the OSD Pro from the circuit, and connect the camera and Transmitter/DVR cable together
directly.
•
Ensure that the OSD Pro is connected correctly to the eLogger/Recorder, and that the LED on the eLogger/Recorder is flashing. If the LED is not
flashing, that means that the eLogger/Recorder is not powered. No video will appear in this case.
•
Ensure that the 3 pin “Video In” connector of the OSD Pro is connected to the output from your camera, with the “S” pin connected to the positive
output of the camera (the center pin for RCA), and the “-“ pin of the OSD Pro is going to the negative output (ground) of the camera (the outer
connector for RCA).
•
Ensure that the 3 pin “Video Out” connector of the OSD Pro is connected to the input of your Video Transmitter or DVR, with the “S” pin connected
to the positive input (the center pin for RCA), and the “-“ pin of the OSD Pro going to the negative input (ground - the outer connector for RCA).
Issue: I have connected the OSD Pro’s “Audio Out” output to my Video Transmitter or DVR. I hear a buzzing or humming sound, or there is distortion in
the audio.
Solutions:
•
Mute the External Audio input as described in the audio setup menu above, if you are NOT using an external (microphone) audio source to hear flight
noises.
•
Make sure you have the voice volume, external volume, and variometer volume set to either 1 or 2.
•
Increase your OSD Pro “Black Level” setting to 5 or above. If this does not resolve it, reduce your OSD Pro “White Level” setting.
•
The audio input of some video transmitters require higher output impedance. Try connecting a 3K to10K ohm resistor (any type of resistor should be
fine) in series with the OSD Pro’s audio output and the video transmitter’s audio input.
Issue: The OSD Pro text is visible when my camera is turned on, but only a black screen appears when the camera is turned off.
Solution:
•
This is correct behavior. The OSD Pro will not overlay text if there is no active video source. Many functions of the OSD will not work if the video
input signal is lost during flight. RTH should still function even if the video input signal is lost, however.
