Good day all I require some help please. I had a DSD 3U decoder running on extra view from the exploria, and changed the DSD 3U to the new HD s5 but I see there is no space for the heart beat cable. If I plug the RF cable in the change it to the lmb then it works for a while then after gives me an error code. How can I resolve this problem and I did set it up on the 5s to be the second decoder.
