I don't have a DRX. It was sent back for credit after Rob told us it absolutely would not work despite Dynon emphatically assuring us it would. This was after I paid $4k to upgrade my 5600 to touch screen and wi-fi to use the DRX. Rob had many conversations with my avionics guy which is what got me as far as I have.
There was much gnashing of teeth about the lack of serial ports on the 5600 by my avionics guy. This is what lead to the failed DRX wi-fi excursion.
My plane has a Garmin GDL 39, Garmin Aera 500 and a Dynon D10 EMS. I've been told (no guarantee on the accuracy of this) that the 5600 gets GPS data from the Aera and Engine data from the D10. I have no idea how the ADS-B data gets to the 5600. I do know that I don't have an external GPS antenna. Apparently it is inside the consol. As part of the Aera 500 or GDL 39?
I'm trying to get ADS-B subscription free weather on the 5600.
