I currently have 3 HR2Xs all hardwired via ethernet (two in the same cabinet, the other next to the router), and am having a new HD IRD (H2X ?) installed in a few weeks. Because the H2X will be in a room that is remote from the router w/ 1 COAX and no CAT5, I am having DECA installed in order to be able to utilize MRV. Can I put a 2nd router/switch/other hardware between the DECA unit and the H2X so I can use the D* hardware to distribute my network? Can I use the second ethernet port on my HR21 in the same way?
