element 0 Posted March 25, 2011 An hour after I installed the 8th camera on my mux16tc multiplexer, the unit froze up completely. I reset the power and now all it does is beep continuously when plugged in, no system check, cams or no cams. Thinking the unit was just used up, I plugged in an identical multiplexer backup only to have the exact same thing happen after 30 minutes. Any ideas why this would happen? Logic says something with the new camera, but when I plug in each camera to test individually to a monitor they all seem fine. Now I am scared to try a quad backup or new dvr until I have more answers.. Share this post Link to post Share on other sites

(everything powered up) Yeah, sounds like the camera in question is throwing back some voltage to the mux, I've had that before but not with a mux - faulty cam. **SORRY GUYS MISREAD ELEMENTS ORIGINAL POST - DISREGARD** Edited March 25, 2011 by Guest Share this post Link to post Share on other sites
SEANHAWG 1 Posted March 25, 2011 The problem you are having is with the power supply that you are providing to the mux. We have the same model and if you do not use a power supply that has atleast 2.5amps, then you will have the problems that you are stating. Share this post Link to post Share on other sites
