Getting Started
•
“IkarusOSD” takes power from the video battery, regulated at 5v. Even to set it from the
USB it's necessary to provide external power.
•
.The connection to the computer via the USB port is made only from the start menu. Once
you are on the flight screens it will require a restart to return to the main menu.
•
The main menu does not appear if motor battery is already connected. This way, if it
restarted during flight by an occasional failure in supply, it would pass directly to the flight
window.
•
Make sure you have selected the correct voltage for different cameras and video transmitter
before connecting to the OSD. Powering a 5V device at a higher voltage may make it
unusable.
•
Connect the GPS receiver to “Ikarus OSD” gps port. Note that the supply voltage is 5V in
this case. If your GPS it's working at a different voltage (typically 3.3V) it must adapt first.
•
To start using “Ikarus OSD” is only necessary to use a single channel on R/C transmitter.
Connect the receiver to the "CTRL" input. Configure the control channel modes initially to
"Slider / Dial", "Switch 2" or "Switch 3" (recommends last one).
•
The remaining ports for connecting servos can be leave unconnected initially. These servos
will be power by the voltage received by the servo "CTRL" input, and not by the internal
regulator.
•
Although not using the autopilot, you can connect the IR sensor to display the artificial
horizon and get familiar with it.
•
Pay special attention not to exchange or reverse the battery motor and video connections.
The third pin in video battery connector, connects directly to the motor. You can burn the
current sensor if you connect it to that pin. You can use this pin with the help of a jumper to
power the entire system with a single battery. This is not recommended, so you can cut it
for safety.
•
To use the telemetry signal embedded in the video, select that option in the setup menu. You
should see a bar code on the left side of the image (you may need to disconnect the USB
and restart the OSD). Set by the adjustable resistor the intensity of white bars, until you see
clearly, without actually distorting the image. If the bar code displays cut up or down,
change the starting line telemetry, to see it centered. Once on the flight screen (in the OSD
and in the PC application), click "Fix Modem." The red "led" in the console should turn
green, indicating proper decoding.
•
From the PC Application, together with the access to all OSD settings, also has some
Wizards to facilitate the tasks of calibration (intensity, RSSI, IR Signal, Servo travels, etc.).
•
If you connect too many devices to internal controller (video TX) verify that the board can
dissipate heat properly and the thermal protection don not jump after a prolonged period
(egg 20 minutes).
