DX7 not calibrating with XTR 5.03

[peter_lanius]

Hi,

using the information in this forum and after much trouble I have got to the point where my Reflex XTR 5.03 actually recognises my DX7 heli radio. What doesn't work is the calibration process. Every time I try, Reflex says that the calibration could not be completed. I have set the Trainer Mode to Normal, Swash Mode to normal and the servo display on the DX7 shows all channels as centered.

Any suggestions would be greatly appreciated.

Thanks
Peter

Hi,

I have had a look at the signal that comes out of the sim cable attached to the DX7 on my oscilloscope and it looks like a standard PPM signal. No obvious noise or any obvious deviation from what it should look like.

Below are two pictures of what the calibration process produces on Reflex XTR. The result is slightly different each time, but all along the same lines as in the 2 example screenshots.

Is there any way to test the correct functioning of the USB dongle?

Thanks
Peter
