We just received fro Directv an HR24-500-A intended to replace an old and failing HR22-100. The HR22 requires a DCA at the input to separate the internet (Ethernet) and the satellite input signal. Does the HR24 also require a DCA??? There is an Ethernet port on the back of the HR24 but it does have an easily removable cover on that Ethernet port. So do we need the DCA on the HR24 or drop it off and just plug the sat signal directly into the input??? thanks..
