Dynon transponder 262 not working

[High_Flyer]

Hello Dynon,
I am finishing the wiring of my skyview system which includes the SV-XPNDR-262 transponder.
Yesterday I tried to see if all was good but I have a transponder fail message on the initial skyview screen,
and when I go in the Transponder setup page, staus shows "NOT FOUND".
In the serial port setup I see the TX counter increasing but the RX counter stays at zero, and the group errors increasing.
I verified all the connections and couldn't find anything wrong, I have good continuity on all wires, good power input, good ground.
I tried to change serial port from port 4 to 1, reconfigured each and still the same.
What do you suggest next?
Thank you.

Fundamentally that means that SkyView isn't hearing from the transponder. The most likely issues are serial port or power wiring that is not correct. Where are you in France? If you're anywhere near Strabourg, our dealer http://www.finesse-max.com/ there may be help to help verify that the transponder module itself is operational.
