The Avidyne DC50 (700-00015-xxx) is no longer serviced nor supported. Aircraft with the DC50 installed having issues should talk with the aircraft manufacturer to ensure the unit can be removed.
The Datalink Coupler is a Radio Frequency (RF) device that allows two transceivers (a VHF communications radio and a datalink radio) to share a single wide-band VHF antenna. The coupler contains filters that allow the signals intended for the comm to reach the VHF comm port, while routing the ORBCOMM datalink frequencies to the ORBCOMM datalink port.
If removing or replacing the DC50, weight and balance must be followed for the aircraft.
