D100 PC communication issue

[picca4]

Hi,
I tried to connect my D100 to my PC as I did many times to retrieve logged data but I didn't succeded. I also tried to determine the firmware version but same issue. The screen on the D100 turns yellow as usual but it stays like that untill, after few minutes, it disconnets and I get on the PC a message stating that it is unable to communicate with chip #4 and I should check the wiring or try with different PC. Fortunately my D100 reboots normally but I am unable to update the firmware to 5.6. Any idea? Thanks

That may indicate a hardware issue, but it might also be the particular PC/EFIS combination. If you can try another PC, that will eliminate the latter. If that doesn't produce better results, we'll need to see your D100 here at Dynon for repair.
