Teach-in of your own transmitter
If you want to use your own transmitter, which you did not purchase bundled with your AscTec UAV, please follow these steps:
Connect the USB module of your wireless data link (XBee 2.4GHz or Radiotronix 868/900 MHz) or the AscTec USB-to-cable adapter to your Windows PC. If your system requires a driver for the USB chip, please download it here: http://www.ftdichip.com/Drivers/VCP.htm.
The USB module will then be recognized as a COMport and appears in the Windows device manager.
Turn on the vehicle and start the AscTec AutoPilot Control software. If you are using the USB-to-cable adapter you need to connect it to ”LL serial 0“ on the AscTec AutoPilot. Click on ”Setup“ in the top left corner of the software and select the right comport. Then click on ”Connect“ and on ”Enable Data Polling“. The red dot next to ”UART Comm“ on the right hand side of the form should turn green. If not, please check your connections and try to reinstall the FTDI driver.
While holding the "shift" button of your keyboard, click the ”Tools“-menu and select ”Parameters“ and on that form click on ”R/C Setup Wizard“. Click on ”Start Wizard“ and follow the instructions given by the program. Please note that you need six channels to control the AutoPilot vehicle: four channels for pitch, roll, yaw and throttle (all four channels should be sticks on the R/C), one channel to enable and di-sable the serial data interface (two or three position switch) and one channel to switch between Manual mode, Height mode and GPS mode (three position switch). If you have never flown a model aircraft before we would recommend the following setup for the first four channels:
Once the R/C setup wizard says ”Calibration data collected“ go back to the ”Parameters“ form and click on ”Transmit Values“. The form should briefly turn yellow (while transmitting data) and then back to grey if the data was transmitted correctly. If it doesn’t turn grey again click ”Transmit Values“ again. After that, click ”Write to FLASH“ to permanently store the new set of parameters in the vehicle’s FLASH-memory.
Now, go back to the "Status Information" window. In the field ”RC Data“ you should now see the values coming from your R/C. With all sticks and switches centered the values should be around 2048. Please verify if your stick inputs are according to the following table:
The correct function of the two switches (serial interface, flight mode) can be verified by looking at the ”Flight Mode“ field on the bottom of the form.
