docedog 0 Posted April 29, 2005 I have a home CCTV configuration set up with 6 cameras, Channel Vision modulators inserting channels into my cable. I am trying to add cable modem access but when I splice it into my system using a 2-port splitter it fails. I am splitting it at the main feed for the cable and as soon as I connect my system to the splitter the cable modem goes down. Could my cable signal be that week that when I connect a third device to the splitter it drags the signal down? I also have a Channel Plus LPF470 Low-Pass filter at the cable access point that seems to block the cable modem signal that I have removed for testing. Question: does a 2-port splitter still lose 3.5db if only one device in/out is connected? Any ideas/comments on this configuration? Share this post Link to post Share on other sites
VST_Man 1 Posted April 30, 2005 couple quick things to check. is there dc voltage on the line? If so you may need a DC blcker to stop it from being split/passed? frequency of the splitter has to be correct for the signal(s). I'm guessing your grounding any dc voltage which is knocking out the signal. Share this post Link to post Share on other sites
