Hi Dave,

thanks again for your assistance. After one day search and complete disassembly of the plane I found the error in the cabling: Someone forgot to connect all data wires with Flarm (at a junction under the seat). Now the communication part between Flarm device and the ILEC is working.

But now I've got the next problem: I decided to put some new airspace and airport information onto the ILEC. So I deleted both pages for the ndb files. After I started the transfer software and connected the pc to the ILEC. The connection started and the ILEC displayed a dialog. Unluckily, I was unable to chose something, as no one of the buttons did accept any input. When I unplugged the serial cable, everything worked again, but then I was unable to transfer the file. So for now, I can't install the ndb files. Did you observe something like that before? Is there a way to install the files by installing them completely by using the PC? My ILEC software version is 2.35. I also tried 2.34, but also without success.

Best regards,
Martin
